<videoflash>6uRC_8_jEes</videoflash> Second Life Tip of the Week #30: Graphics Preferences Guide

The following are 3 different text transcripts of the above video tutorial. These weren't edited, and there are typos. You're most welcome to correct them — your help is appreciated! — and let Torley know if you find this useful (it's currently being done experimentally via MTurk).

Version 1 - A3JBRQHOEQVDZW

Amicable salutations. It's me! Torley Linden, of course, and oh! I've gone shopping it seems, thank to Tutu Claxton who made this avatar. If you're wondering, where are the watermelons? Look closely, there's green and pink right there. And there's more melons. Ha ha! Anyway, let's get started.

In today's tip of the week, I'm going to cover the graphics preferences. What you need to know. A guided tour is showing you what just about everything does. Follow me and let's come along.

Edit menu, and preferences, and graphics. Now, by default it's a simple slider. And normally if you click recommended settings, it will optimize depending on your hardware. If you have supported hardware (and I highly do recommend that), meet the system requirements, or meet the system recommendations (even better), then you should be able to enjoy all of the graphics options in their glorious entirety. Otherwise, you may not be able to turn some of them on. I also advise you to upgrade your graphics drivers to the newest stables versions, whether you're on Invidea or ATI.

Now, enough of that talk. There's time for more show. So custom. This button, it enables all these options under here. Because normally you can one-click set it, right? Like set it to mid, for example. Set it back to low. And custom will give you more granular control. There we go, a lot of options.

And you may say, "Oh my gosh, this looks complicated." Well, there are a few simple principles which you should remember. For example, sliders to the left will mean that they are faster, the performance will be faster, and the quality will be less. Such as, mesh detail for objects. You turn to the left, it will be low. To the right, it will be high. This principle is true for all of them. Generally also, checking things will turn on options and make things slower with some exceptions. Such as avatar imposters, which I shall show you later. It one of my favorite viewer optimizations. Boosts your frame rate.

OK, so let's start right here at the shaders part. That's a nice starting place. Bump mapping and shiny. We may remove this in the future. Just about everyone can have this turned on. So, if I'm going to res a cube right here. With that off, I'll zoom in, test your shiny. It does nothing. But when I turn this on, now it has shiny. I move my camera, shiny, shiny, shiny. You can set it to shiny high.

And the bump mapping refers to this bumpiness. We don't yet have support for custom bump maps, but we will hope to in the future with materials. That's our keyword for having a versatile system for objects that can get beyond this. But right now you can add extra depth, make it look more 3D with these bump maps. So you can combine those and it looks pretty cool that way. Sort of.

The sky's not supposed to be white that way. I think there's something buggy with that. It's not supposed to blink on and off. That is, though, because I don't have even basic shaders even on. If I'm going to turn basic shaders on, then the world is going to look more beautiful. So let me just angle up there, and then turn basic shaders. There should be subtle differences and the terrain should also get sharper.

By the way, if your terrain looks splotchy, set it to high. See, crisper detail right there. This would normally be great out on higher end configurations. When I turn on the basic shaders. There we go. You see right there. Well the water I mean. I meant the water looks nicer already. See. Notice it went off. The way is like a inky. Then when it's on, ooo, it's going to get better. Things are going to get better. Getting betting all the time.

OK. Now, atmospheric shaders. If you've heard of WindLight, that's the code name for our atmospheric rendering technology, providing physically accurately modeled lighting effects, and atmospheres, and environments. Woo! So, when I turn this on, notice the sky. It will light the ground. It will have a greater dynamic range. It will just look more realistic, put it that way. And the sky will have nicer clouds and stuff.

Yeah, there we go. See. So now I've got this. It's more noticeable at some times of day. Like if I was to go to world menu, environment settings, and sunrise. OK, note how the sun looks. Ooo! Beautiful, beautiful, beautiful. And if I turn off those shaders, then it's going to look not so beautiful. The clouds have gone away, it looks anemic, and it's just fading out.

It's not supposed to turn white like that. Oh there we go. Yeah, it's kind of pale. It's flashing at me. That seems buggy. I'll just turn it back on. If you can possibly turn that on, if your card, GPU graphics card, has DirectX 9 or higher shader support, you should be able to.

And next, water reflections. This does what you think it should do. However, it is rather taxing and may cause a severe performance hit, depending on your system. On higher end systems, not so much. But the best way to find out, try it, right?

I hear the sound of dropping boxes or something.

Let me go back to midday, and I'll turn it on and off to show you. So, I'm with the waters, and we don't have reflections so the water looks nice. So I turn them on. OK, that was a subtle change. Did you notice that? If I put something over the water. Oh, this is probably very recognizable. Oh, it has levels.

So terrain and trees, this means Linden trees, not resident created ones out of prims. So notice those aren't going to be reflected. But static objects, you can move. These go up cumulatively, successively, I mean. Then you start to turn on extra details. Let me get my avatar on top of the water so you can see. And actually, what I can do here is go to world, environment settings, and environment editor. I want to change the water and make it glassy. That way you can easier see the reflections, because it's glassy, like Philip Glass.

OK. Now I will turn on all avatars and objects. And there! There you see, my avatar is a reflection. Before I was a vampire, or something like it, but now I'm not. See? Then it adds that. So, terrain, all static objects, all avatars and objects, and now everything.

Everything has a benefit, also, of, you may not have noticed a difference there, but if there were things like particles, that would've shown up. Oh! Let me show you quickly actually, there's a particle, I think there's a waterfall. Oops, not a wayerfrall, a waterfall, a waterfall particle system.

Let me just quickly do this. Don't mean to rush you, but just to show you a quick demonstration. I know you don't have a lot of time sometimes, and I want to get this information nice and quick. I'll just copy that. Just paste it in there. Oh, it's going slow. That's not my library. It's confusing. It's kind of moving slowly. There we go.

OK, so waterfalls, right? I mean waterfall particles. This is just a particle system. It's emitting a fine mist. Let me put it over the water like that. Then, as you can see, the particles are also reflected. Normally if you don't have that everything, then they're not going to be. So it adds extra detail.

Sometimes there's things like night, I think. Let me just check this to be clear. Yeah, you notice the stars, if you look very closely at the stars. They are also reflected in the water. Kind of hard to see that, but it's beautiful. That what you need to be. Beautiful!

OK. Well, before we... Avatar imposters is like the tour de force here. I'll get to that I promise.

Draw distance - how far you can see off into the distance, as it says. You turn this up higher and it will let you see further. So 64 is the lowest, and you crank it up, and you can see further. You know, so there's trees and there's going to be other things. Keep in mind, the higher you set it, the slower Second Life will be, because it needs to render all these objects. And if you're looking very far away, that going to be a lot more resource usage. It's already kind of.

You'll see there's parts of this building appearing here. Slide it back down. Usually 128-192 is typical. See how it works for you though. That's what it is though.

Max particle count. Oh, this is a good one! It says we have a particle emitter right here. You can control how many particles you see on screen at one time. Too many may be so-called laggy. So if you turn them all the way off, you're not going to have any. And you can turn them all the way up, then you're going to see more on the screen at one time. Typically you can set this about 4,096. That's the typical number. Post process quality.

OK, you're like, "What does that mean?" And by the way, there's this question mark here. You can always click this to get help. So, like it says. Sets to resolution with which glow is rendered. Now, let's have a look at glow. Right click, and I'm just going to drag this up. Now many of these graphics option are within the texture tab, and glow is too. So I can set glow. OK, the object is glowing.

I just move these little. They're called spinners, these little arrows here, spinners. And I can set it to high. Let's see if that makes a visible difference for us. It may be easier to see this in the dark, since it's glowing. Maybe not. We can set the glow higher. Let's see, glow to high. There's only two settings there. It's subtle. So, see how that goes for you.

Ah, mesh detail. So, I'm looking at a detailed mini map of sorts. Not the same as this mini map, but it's right out here in the open. It's got sculpted prims. It's got a fair amount of very small and detailed geometry. So this is a good candidate for preferences and the mesh detail objects, because when I set it to low, it will reduce the number of polygons, which means that objects will look crappier, but they wouldn't impose as much of a rendering burden.

Notice that? OK. So, now they look very, very, they don't look the same as before, and notice how the round things, they look more like hexagon platforms. If you scale it up to maximum, the high, then it gets better looking. Sometimes stuff may still look residually artifacted, I mean, degraded like that. So, move your camera in and out to adjust that. Low. High. So that's what that does.

Flexiprims. That is, OK, let me get a flexiprim here. I haven't noticed, I think there may be a bug which this, which doesn't work it is fixed. I'll create something. Let me create a flexiprim. I'll stretch up this prim. I love giving you illustrated examples of stuff. And in the features tab, you notice right here, flexible path. This makes it all wiggly. Wiggly prim! OK, I can't quite see the wiggliness yet. Let me just drag it up, and it will get wiggly when I start wiggling it. Ooo, wiggles. Now notice, it's literally a flexible prim.

This likely has an effect when there's a lot of them on the screen at once, where it should. And then it controls the smoothness of how they wiggle.

I'm going to make a few more. They're kind of like those wavy tube man guys that you see at some used car sale places. I'm just copying a whole bunch of them. I mean, I'm going to clean up after. I'm not going to be bad about this. So then we can wiggle them. Let's see if it makes a difference though. That's what I came here to show you.

So they're kind of smooth. They're moving slowly. Let's see, move to high. Does that make a difference? Low. Well, it doesn't seem to be much of an apparent difference. I'll go ahead and report it as a bug. That's still being a problem.

Let's move on. We are here at Linden World Lobby. Trees, trees, the magical food, or something like that.

Tree mesh detail controls the detail of Linden trees. And how do you know if it's a Linden tree? Well probably the easiest way is just to right click and edit. If you notice these are grayed out, then it's a Linden tree. You can't script a Linden tree, and they have a number of limits. They're strange that way. Also, it doesn't glow. Notice like other objects have a tutorial on the trouble with Linden trees.

But anyway, so you'll notice, if I move to low, from a further distance, they're probably going to look more like cardboard cutouts. And if I move it to high, they should become richer. Yeah. See. It's kind of inconsistent sometimes, but notice. Low. High. Low. They look really anemic. And they look just like flat. And then High. Of course, high will make them render slower, too, once you get closer.

Avatars. Oh, this one would probably be a good one for a crowded place. I'm just teleporting from scene to scene here. Let me go to a place with a lot of avatars, and we can see what that does, eh? Actually avatars used in correlation with avatar imposters. That will be useful. So let's save this one for a little bit later.

Terrain. Yeah, this is a good one for a bumpy place. I should show you somewhere that has... Oh, even this would do actually. Some place with curves. So when terrain mesh detail is low, terrain may look more jagged. It's not going to look as organic and flowing. But it's high, notice. High. Low. High. Low.

This becomes most apparent at mountains. Let me show you a good mountain range for that. Mountain range found and located. Notice terrain has a level of detail, meaning when you zoom in, of course it gets more detailed, more roundy. But when you're off like this and terrain is low, it looks like a 90s video game. So when I make it to high. Notice, better. Low. High. Low. High.

And by the way, I know some of you are going to ask, and I should cover this in a future video tutorial. In advanced menu and debug settings here, there are a bunch of things which one has in addition to this. Power user tweakage. So, for now, I'm just going to show the basics. If you're curious, you can watch that later. Low. High. Low. High. They're like doing the dance. I like that song.

And sky mesh detail, finally. Of all these mesh details, it just makes the sky look better, of course. If you set it to low, they're going to look blockier. This is most noticeable with some types of suns I think. If I set it to a sunset. And let's go here. Triangles in the sky. Low, so you notice. So it's not so round. It's a little bit off. High. Low. High. Low. High. And let's see here.

Let me grab a custom preset I did here. Some of my presets illustrate this really, really well. I have a lot of them here, don't I? That's crazy. OK, I think this one has this. Notice how blocky that looks? It doesn't look natural at all. Low. High. Low. High. This can be pretty taxing too, depending on your setup. So again, watch your performance. If things start to feel really slow, you can always go back. That's pretty cool.

Lighting detail. Oh my gosh! You need to know about this. This is great. This is for what they call local or point lights. These are controlled through objects that are lit in the features. Let me see here. I'll just go to a normal sort of... let me go to midnight actually. Dark.

And I'm going to res a cube again, as I often do. And in features, right here, light. This is what makes it a light prim, lit prim. Then I can zoom in, and it's not going to be lit up, because lighting detail, it's only the sun and moon. But when you turn on nearby local lights. And then it should pop open, and I mean not pop open literally, but you should see there's a light here, right? And you can change the color of the light to different things.

Important consideration, however. Only the 6 nearest lights to your avatar are you going to see. This is due to an open GL graphics protocol limit. If you've got more than that, you're not going to see the face. You'll notice theres 3, right? And then there's 3 more. We can make these, this line. You can adjust them one at a time. Well, they're all green. You can see they're clearly emanating lights, so 6. However, notice when I make another 3. See, the ones in the middle, they don't have light right now, because they're not selected. But when I deselect, only the 6 nearest to me are going to be lit. Just like that, see. And then if I move these ones closer to me, my avatar right there, then these ones aren't going to be lit.

So keep that in mind, if you're wondering... Oh darnit, I crashed. Oh my gosh. Pardon about that. After the crash, my preferences graphics here were reset. But that's OK. I can keep illustrating from various principles.

Hardware skinning. You should generally turn this on if you can. If you're on older hardware that's unsupported, this may cause problems. There's a probability of that. It's a slight acceleration for your avatar rendering. Turn it off if you think, it's doing stuff. And once that's on, notice that avatar cloth is also enabled. Avatar cloth means that you have something like notice avatar mesh.

Oh my gosh, this is a lot of boxes. Let me just turn these off. I know now I look so naked. It's not technically, you know, that's weird.

So if you're wearing mesh clothing, in appearance, keep in mind like a mesh skirt. This would be a mesh skirt right under here. Or not a shirt, I mean skirt. Then, avatar cloth, when cloth is on, it means it will ripple. Let's see if we can see an example of that.

It's off, so it's not rippling in the wind when I fly. But when I turn it on, this adds an extra touch. Maybe nice, maybe distracting. So now, avatar cloth is on. You'll now notice, look very closely, there's some rippling action there. Very subtle. Look at that. Whoa, you didn't need to see that. OK. It's kind of like my buttocks there are rippling. So, it has a good effect. It's noticeable with longer kinds of coats.

Next up. And remember, a good guideline is if you're confused, you can just click one of these. And then with custom open, it will show you all the details that went into making that. So you can say, hey, OK I know what this is roughly equivalent to and what settings, specifically, make up the high setting versus the mid setting, for example. Then you can compare and say, I want to tweak this, and this is a little bit better taste.

If you want to go all out, pig out on your graphics buffet, then ultra is the way to go. Yeesh! And speaking of ultra, in a wave, in a manner of speaking.

Hardware options. This has additional options above these, which mean increase quality even more. Click that button, and this will come up. Filtering. Anisotropic filtering. You're like, what the heck is that? You can look it up on wikipedia. The long story short, objects with textures at oblique, or not right on angles. They will look slightly sharper.

This may be kind of hard for me to show, because of the video. When I recorded video, there some deterioration that's fine details. But you can compare it on and off. Try making some objects that are in the far distance and have textures. Like say a sign with text on it. Antialiasing is more noticeable. We added this recently. This is good, because before you had to go to your graphics drivers preferences.

Now the big thing about antialiasing is it smoothes out jaggies. If you think your Second Life looks too jaggy, you can turn this up. I can go up to 16. Depends on your graphics hardware. You may not be able to attain this. Some can go even more than that. But if you disable it... Let me see if I can show you. This is one of the biggest determinants. Especially if you take photographs, a lot of snapshots in Second Life. This will impact the quality of those.

So, let's see here. You can see the edges. Look at the fine edges of this hutch thing. And let me turn off. So when I disable it, the screen will blank for a while, and it will just take a moment to switch resolution, as it says. OK, just give that some time. And I hope it doesn't kill me. There we go. And notice, I'm going to zoom in obviously on this, it's jaggier. You can see it's jaggier.

Hardware options and make it back to 4. OK. And now, smoother. So play with that. The higher, the better. What antialiasing, it renders a scene the number of multiple times it is actually shown, and it scales it down. So it obviously, it's more, it can slow things down, but for the price you're paying, it can look very nice. Make Second Life look nicer.

OK. Gamma. This and fog distance ratio are grayed out. Now the reason why is because, let me go back here. Atmospheric shaders overrides them with control of its own. If I were to disable the atmospheric shaders again. Hardware options. You'll notice I can set my gamma.

I don't find it too useful. And fog distance ratio, this contains basically how much fog is. If you set it low, then things should look foggier. But it doesn't really work too well. You'll notice, only the trees are foggier there. I think that's kind of broken. It's not working the way it should. So, I don't really bother with that. I just keep atmospheric shaders on. And you'll probably want to keep it, usually far so that things don't look weird like that.

Texture memory. This is normally auto detected to how much you have on your graphics card. If you have like SLI or ATI's crossfire, this sometimes, some occurrences may auto detect wrong. In which case you can override it. I personally have not noticed a big difference between setting it, say, lower and higher.

That much, you don't want to set it tremendously low, because you're probably going to end up with flickering textures, because they all can't get loading memory. I'd say set it to 128 and up, typically, but see what works best for you. This really depends on your specific hardware. This is why we let you override it. In the past, we didn't. Ah yes,

OK. We've got to get to avatar imposters. So let me find a club with a lot of people. T-Dub in the club, for shizzle. Haha. We are here!

Now, notice how some of these avatars, they are animating less smoothly, and they look like they have sort of fringy edges. This is because avatar imposters is on. Avatar imposters is a pretty cool feature. You may ask, "Why would you want to imposter someone? What does it literally mean to fake someone out like that?" It means avatars in the distance are going to be drawn representationally like a 2D cardboard cut-out. Think of old Nintendo games, right? Where someone had a two cycle walk.

So it means they're going to be animated and look somewhat less smooth. The tradeoff is a performance boost. I can exhibit this, and I've shown this before, but let me show you here today, since you're watching this. View menu and statistics bar. Let's compare this basic frames per second. This is 10. It's OK. If I turn avatar imposters off. Now, it should slow down noticeably.

Yes, notice how there's a slight performance hit. Now, if I turn avatar imposters back on, it raises back up. This is because, by having to render these further avatars, and thank you to Renetay Linden for the explanation. Then having using less cycles like that results in the performance gain. And if you think avatars are becoming blocky too close, this is precisely because avatar mesh detail, it correlates. So, by high, it means avatars become imposters at further distances.

If you want a greater performance boost, set avatar mesh detail to low, and avatars will become imposters at nearer distances. So again it's a tradeoff. Do what's best for you. Notice now that the avatars that are nearer, they look somewhat blocky. However, I'm experiencing a performance gain. And then remember, turning it off will slow down performance. This works great on a lot of systems. However, if you an have older, unsupported Intel integrated graphics card, it would probably be best to turn it off. You may experience some artifacts or other weirdness. And that's in line with what I recommended before.

There's a lot of crazy sounds here! So remember, the power is really in your hands. Avatar imposters is great with crowd scenes. Keep it on, and if you want people to become imposters at further distances, then set it to high. Let me go back to when we were in the club to demonstrate.

You can tweak any of these just about any time you want. If custom is off, of course it's simple. But it's good to gain an understanding of what each one of these does. Then you can fine tune your experience and maximize your enjoyment of Second Life. If you consider all these options and what each of them does, and you learn through by observation, just by seeing what each one does, and of course watching this video, thanks for watching. You'll clearly gain a better knowledge and feel more confident about using stuff.

So, that's the graphics preferences in Second Life for you. I hope you've had a good time. There's certainly more things to cover. Like I mentioned, in Advanced, there's additional hidden options. And over time we've optimized this. Like before, it used to be 3 tabs, and now it's one, making it simpler. I'm Torley Linden. I'm going to see what else is going on here. I see they're using some glow and some other techniques. All these things put together comprise what you see and enjoy and experience in Second Life.

Thanks for watching this video tutorial. Please rate, comment, favorite, and subscribe to my videos on youtube if you like them. It helps them gr-gr-grow! And if you have any questions or comments for me, go ahead and email me: torley@lindenlab.com. I'd be glad to hear about your video tutorial curiosities and inquisitions, not in the bad sense. Queries.

And I have stepped into the glow, and I'm going to, so-called, duck out for now. Stay tuned for more video tutorials.

Version 2 - ARQ4J4TLTPBNC

Amicable salutations. It’s me, Torley Linden of course. I’ve gone shopping it seems, thanks to [ ??? Clacksen ] who made this avatar. If you’re wondering, where are the watermelons? Look closely. There’s green and pink right there. And there’s more melons… Anyway let’s get started. In today’s Tip of the Week I’m going to cover the Graphics Preferences. What you need to know, a guided tour showing you what just about everything in there is. Follow me and let’s come along. Edit Menu and Preferences and Graphics. Now by default it’s a simple slider and normally if you click it, recommended settings it’ll optimize, depending on your hardware. If you have supported hardware, and I highly do recommend that, meet the system requirements or meet the system recommendations, even better, then you should be able to enjoy all of the graphics options in their glorious entirety. Otherwise you may not be able to turn some of them on. I also advise you to upgrade your graphics drivers to the newest stable versions, whether you’re running Videa or ATI. Now enough of that talk. There’s time for more show. So custom. This button, it enables all these options under here. Because normally you can one-click set it, right? Like set it to mid, for example, set it back to low. And custom will give you more granular control. There we go. A lot of options. And you may say, “Oh, my gosh! This looks complicated.” Well there are a few simple principles which you should remember. For example, sliders to the left will mean that they are faster, the performance will be faster and the quality will be less. Such as Mesh Detail for Objects, you turn to the left, it’ll be low, to the right, it’ll be high. This principal is true for all of them. Generally also checking things will turn on options and make thing slower, with some exceptions. Such as Avatar Imposters, which I shall show you later, it’s one of my favorite viewer optimizations. Boosts your frame rate. Okay. So let’s start right here in the shadiest part. That’s a nice starting place. Bump mapping and Shiny. We may remove this in the future, just about everyone can have this turned on, okay? So if I’m going to rez a cube right here, with that off, zoom in, texture shiny. See? Does nothing. But when I turn this on, now it has shiny. I move my camera. Shiny, shiny, shiny and the Bump Mapping refers to this bumpiness. We don’t yet have support for custom Bump Maps in normal maps but we will hope to in the future with materials, that’s our key word for having a versatile system of objects that can get beyond this. But right now you see you can add extra def, make it look more 3-D with these Bump Maps. Okay? So you can combine those and it looks pretty cool that way. Sort of. The sky’s not supposed to be white that way. I think there’s something buggy with that. Not supposed to blink on and off. That is though because I don’t have Basic Shaders even on. If I’m going to turn Basic Shaders on – let me turn that off – then the world is going to look more beautiful. So let me just angle up there. And then turn Basic Shaders. There should be subtle differences and the terrain should also get sharper. By the way, if the terrain looks splotchy set it to high. See? Crisper detail right there. This would normally be grayed out on higher-end configurations. When I turn on the Basic Shaders, there we go, see right there? I meant the water looks nicer already. Notice with it off? Ew. The water’s like inky and, with it on, it’s going to get better. Now. Atmospheric Shaders. If you’ve heard of WindLight, that’s the code name for our atmospheric rendering technology providing physically accurately modeled atmospheres and environments. So, when I turn this on, notice the sky, it’ll light the ground. It’ll have a greater dynamic range. It’ll just look more realistic, put it that way. And the sky will have nicer clouds and stuff. It’s more noticeable at some times of day. Like if I was to go to World Menu, Environment settings and Sunrise. Note how the sun looks. Beautiful, beautiful, beautiful. And if I turn off those Shaders then see. Now look. They look not so beautiful the clouds have gone away it’s just fading out, it’s kind of pale. It’s flashing at me. that seems buggy. If you can possibly turn that on, if your card GPU graphics card has X-9 or higher shader support, you should be able to. And next. Water reflections. This does what you think it should do however, it is rather taxing and may cause a severe performance hit. This does what you think it should do depending on your system. On higher-end systems not so much, but the best way to find out? Try it, right? I hear the sound of dropping boxes or something. Let me go back to mid-day and we don’t have reflections over the water so it looks quite nice. So I turn them on. That was a subtle change. Did you notice that? If I put something over the water. Oh, this is probably very recognizable. It has levels, okay? So terrain and trees, this means linden trees not resident created ones out of prims so notice those aren’t going to be reflected. But static objects, you can move these go up and cumulatively, successively I mean then you start to turn on extra details. Let me get my avatar on top of the water so you can see. And actually, what I can do here is I can go to World Environment settings in Environment Editor, I want to change the water and make it glassy. That way you can easier see the reflections. Because it’s glassy. Like Philip Glass. Now I will turn on all avatars and objects. And there. There you see, my avatar’s a reflection. Before I was a vampire or something like it and now I’m not, see? Then it adds that. Terrain. All static objects. All avatars and objects. And now everything. Everything has a benefit also of, you may not have noticed a difference there but if there were things like particles that would have shown up…oh, let me show you quickly actually, there’s a particle…I think there’s a Waterfall…A Waterfall Particle System. Just quickly do this. Don’t mean to rush you. But just to show you a quick demonstration, I know you don’t have a lot of times sometimes and want to get this information nice and quick. Let me just copy that, just paste it in there. Oh, it’s going slow. That’s not my library. It’s confusing. It’s kind of moving slowly. There we go. Okay. So Waterfall Park, this is just a particle system. It’s emitting a fine mist. Let me put it over the water like that. And then, as you can see, the particles are also reflected. Normally if you don’t have that everything, then they’re not going to be. So it adds extra detail. Sometimes adds things at night, I think. Let me just check this. You notice the stars? If you look very closely the stars are also reflected in the water. Kind of hard to see that, but it’s beautiful. That’s what you need to be. Beautiful. Okay. Well before we…Avatar Imposters is the tour de force here. I’ll get to that, I promise. Draw Distance. How far you can see off into the distance as it says. You turn this up higher and it will let you see further. So 64 is the lowest and you crank it up and you can see further. You notice there’s trees and there’s going to be other things. Keep in mind the higher you set it, the slower Second Life will be because it needs to render all these objects and if you’re looking at a very far way away that’s going to be a lot more resource usage but you see there’s parts of this building appearing here. Slide it back down. Usually 128, 192 is typical, see how it works for you though. That’s what it is though, right? Max Particle Count. Oh this is a good one since we have a particle emitter right here. You can control how many particles you see on screen at one time. Too many may be so-called laggy. So if you turn them all the way off you’re not going to have any. And you can turn them all the way up then you’re going to see more on the screen at one time. Typically you can set this about 4096, that’s the typical number. Post Process Quality. Okay. You’re like, “What is that?” And by the way, there’s this question mark here. You can always click this to get “help”. So, like it says “sets the resolution with which glow is rendered”. Now let’s have a look at glow. Right click and just going to drag this up. Now many of these graphics options are within the texture tab. And glow is too. I just move these little spinners, these little arrows here, spinners. And then I can set it to high, see if that makes a visible difference for us. May be easier to see this in the dark since it’s glowing. Or maybe not. We can set the Glow higher. Let’s see. Glow to high. There’s only two settings there. It’s subtle, so see how that goes for you. Mesh Detail. So I’m looking at a detailed mini-map of sorts, not the same as this mini-map, but it’s right out here in the open. It’s got sculpted prims. It’s got a fair amount of very small and fairly detailed geometry. So this is a good candidate for Preferences and the Mesh Detail Objects because when I set it to low it will reduce the number of polygons, which means objects will look crappier but they won’t impose as much of a rendering burden. Notice that? So now they look very, very…they don’t look the same as before and notice how the round things they look more like hexagon platforms. When we scale it up to maximum, the high, then it gets better looking. And sometimes stuff may still look residually artifacted, I mean degraded, like that. So move your camera in and out to adjust that. Low. High. So that’s what that does. Flexiprims. That is…okay, let me get a flexiprim here. I think there may be a bug with this which it doesn’t work unless that was fixed. If I create something. Let me create a flexiprim, stretch out this prim. I love giving you illustrated examples of stuff and in the features tab, you notice right here, flexible path -- this makes it all wiggly. Wiggly prim. Okay, we can’t quite see the wiggliness yet. Let me just drag it up and it will get wiggly when I start wiggling it. Wiggles. Now notice it’s literally a flexible prim. This likely has an effect when there’s a lot of them on the screen at once where it should and then it controls the smoothness of how they wiggle. I’m going to make a few more. They’re kind of like those wavy tube men guys you see at some used car sale places. I’m just copying a whole bunch of them. I mean I’m going to clean up after! I’m not going to be bad about this. A lot of them. Let’s see if it makes a difference though. That’s what I came here to show you. They’re kind of smooth. They’re moving slowly. Let’s see if we move it to high does it make a difference. Low. High. Hmm. Well doesn’t seem to be much of an apparent difference. [ ??? } reported it as a bug. May still be a problem. Let’s move on. We are here at Linden World Lobby. Trees, trees the magical food or something like that. Tree mesh detail controls the detail of linden trees. And how do you know if it’s a linden tree? Well, probably the easiest way is just to right click and edit and if you notice these are grayed out then it’s a linden tree. You can’t script a linden tree and they have a number of limits. They’re strange that way. Also it doesn’t glow notice like other objects. I have a tutorial on the “Trouble with Linden Trees”. But anyway, so you’ll notice if I move it to low from a further distance they’re probably going to look like cardboard cutouts and if I move it to high they should become richer. Yeah, yeah. See? It’s kind of inconsistent sometimes. But notice: high. Low. They look really anemic. They look just like flat. And then high. Of course high will render slower too as you get closer. Avatars. Oh this would probably be a good one for a crowded place. I’m just teleporting from scene to scene here. Let me go to a place with a lot of avatars and see what we can show you that that does, eh? Actually avatars used in correlation with Avatar Imposters, that’s a good one. So let’s save this one for a little bit later, okay? Terrain Mesh Detail. This is a good one for a bumpy place. I should show you somewhere with…even this would do actually. Someplace with curves, okay. So when Terrain Mesh Detail is low, terrain may look more jagged, it’s not going to look as organic and flowing. When it’s high, notice: high. Low. High. Low. This becomes most apparent at mountains. Let me show you a good mountain range for that. Mountain range found and located. Notice terrain has a level of detail meaning when you zoom in of course, it gets detailed, more roundy. But when you’re off like this and terrain is low…It looks like a ‘90’s video game. So when I make it to high, notice? Better. Low. High. Low. High. And by the way I know some of you are going to ask, and I should cover this in a future video tutorial, an advanced menu and debug settings here there are a bunch of things which will enhance your quality in addition to this. Power user tweakage. So for now I’m just going to show the basics. If you’re curious you can watch that later. Low. High. Low. High. They’re like doing the dance… And Sky Mesh Detail, finally, of all these mesh details it just makes the sky look better of course. If you set to low they’re going to look blockier. This is most noticeable with some types of suns I think. If I set it to a sunset. Let’s go here. Triangles in the sky with the low, see, notice? So it’s not so round, it’s a little bit off. And high. Low. High. Low. High. And let’s see here. Let me grab a custom pre-set I did here. Some of my pre-sets illustrate this really, really well. I have a lot of them, don’t I? I think this one has this. Notice how blocky that looks? Doesn’t look natural at all. Low. High. Low. High. Low. High. Low. High. This can be pretty taxing too depending on your setup so again watch your performance; if things start to feel really slow you can always go back. That’s pretty cool. Lighting Detail. Oh my gosh! You need to know about this. This is great. This is for what they call local or point lights. These are controlled through objects that are lit in the features. Let me see here. I’ll just go back to a normal sort of…let me go to midnight actually. It’ll be dark. And I’m going to rez a cube again, as I often do, and it features right here, light. This is what makes it a light prim. Okay? And I can zoom in. And it’s not going to be lit up because lighting detail is only the sun and moon but when you turn on nearby local lights and then it should pop open, I mean not pop open literally, but you should see there’s a light here. And you can change the color of the light to different things. Important consideration, however, only the six nearest lights to your avatar are you going to see. This is due to an open GL – graphics protocol limit – if you’ve got more than that you’re not going to see them. So notice there’s three. Right? We can make this line. You can adjust them one at a time. Well, they’re all green, you can see they’re clearly emanating light. So six. However notice, if I make another three, see? The ones in the middle they don’t have light right now because they’re not selected but when I deselect only the six nearest to me are going to be lit. Just like that, see? And then if I move these ones closer to me, my avatar right there, then these ones aren’t going to be lit. So keep that in mind if you’re wondering…Oh! Darn it! I crashed! Pardon about that! After the crash my preferences graphics here were reset. But that’s okay I can keep illustrating various principles. Hardware skinning. You should generally turn this on if you can. If you’re on older hardware that’s unsupported this may cause problems. There’s a probability of that. What it does is a slight acceleration for your avatar rendering. Turn it off if you think it’s doing stuff. And once that’s on notice that Avatar Cloth is also enabled. Avatar Cloth means that we have something like, notice…my gosh, this is a lot of boxes. Let me just turn these off. I know now I look so naked. It’s not technically, you know… that’s weird. So if you’re wearing mesh clothing in appearances, keep in mind like a mesh skirt, this would be a mesh skirt right under here… or not a shirt, I mean skirt. Then Avatar Cloth, when Cloth is on, it means it’ll ripple. Let’s see if we can see an example of that. It’s off, so it’s not rippling. It’s not rippling in the wind when I fly. But when I turn it on, this adds an extra touch. May be nice, may be distracting. So now Avatar Cloth is on. And now notice. Look very closely. There’s some rippling action there. Very subtle. Look at that. You didn’t even see that. Okay. See? It’s kind of like my buttocks there are rippling. So, it has a good effect. It’s noticeable with longer kinds of coats. Next up. And remember a good guideline is if you’re confused, you can just click one of these and then with Custom Open it’ll show you all the details that went into making that. So you can say, “Hey, okay. I know what this is roughly equivalent to and what settings, specifically, make up the high setting versus the mid setting”, for example. then you can compare it and say “hmm... I want to tweak this. And this is a little better to taste.” If you want to go all out, pig out on your graphics buffet then Ultra’s the way to go. And speaking of Ultra, in a manner of speaking, Hardware Options. This has additional options above these which may increase quality even more. Click that button and this will come up. Filtering. Anisotropic Filtering. You’re like “what the heck is that?” You can look it up on Wikipedia. The long story short, objects with textures at oblique, or not right on angles, they will look slightly sharper. This may be kind of hard for me to show because of the video, when I record the video there’s some deterioration, it’s fine details. But you can compare it on and off. Try making some objects that are in the far distance and have textures. Like say a sign with text on it. Antialiasing is more noticeable. We added this recently. This is good because before you had to go to your Graphics Drivers Preferences. Now the big thing about Antialiasing is it smoothes out jaggies. If you think Second Life looks too jaggy, you can turn this up. I can go up to 16, depends on your graphics hardware. You may not be able to attain this, some can go even more than that. This is one of the biggest determinants especially if you take photographs, a lot of snapshots in Second Life, this will impact the quality of those. So let’s see here. You can see the edges, look at the fine edges of this hut thing. And let me turn off, okay, so when I disable it and, okay, the screen will blank for a while, and it will just take a moment to switch resolution, as it says, just give that some time and there we go. And notice, look. I’m going to zoom in obviously on this, you can see it’s jaggier. You can see it’s jaggier. Hardware Options and make it back to four. Okay. And now, smoother. So play with that. The higher the better. What a does it renders a scene the number of multiple times it’s actually shown and it scales it down. So it obviously can slow things down but for the price you’re paying it can look very nice. Make Second Life look nicer. Okay. Gamma. This and Fog Distance Ratio are grayed out. Now the reason why is because, let me go back here, Atmospheric Shaders overrides them. If I were to disable that, Atmospheric Shaders, again, Hardware Options, you’ll notice I can set my Gamma, I don’t find it too useful. And Fog Distance Ratio this contains basically how much fog, if you set it low then things should look foggier. But it doesn’t really work too well. You notice only the trees are foggier there. I think that’s kind of broken. It’s not working the way it should. So I don’t really bother with that. I just keep Atmospheric Shaders on. You probably want to keep it usually far so that things don’t look weird like that. Texture Memory. This is normally auto-detected to how much you have on your graphics card. If you have like SLI or ATI’s Crossfire sometimes some occurrences may auto detect wrong in which case you can override it. I personally have not noticed a big difference between setting it, say, lower than higher. That much. You don’t want to set it tremendously low because then you’re probably going to end up with flickering textures because they all can get low in memory. I’d say set it to 128 and up typically but see what works best for you. This really depends on your specific hardware. This is why we let you override it. In the past we didn’t. Ah, yes. Okay. We’ve got to get to Avatar Imposters. So let me find a club with a lot of people. We’re here now. Notice how some of these avatars, they’re animating less smoothly and they look like they have sort of fringy edges. This is because Avatar Imposters is on. Avatar Imposters is a pretty cool feature. You may ask, “Why would you want to imposter someone?” Well it doesn’t literally mean you’re going to fake someone out like that. It means avatars in the distance are going to be drawn representationally like a 2-D cardboard cutout. Think of old Nintendo games right, where someone had a two-cycle walk. So it means they’re going to be animated and look somewhat less smooth. The trade off is a performance boost. I can exhibit this, and I’ve shown this before, but let me show you here today since you’re watching this, View menu and Statistics Bar. Let’s compare this basic frames per second, okay? And if I turn Avatar Imposters off, now, it should slow down noticeably. Yes. Notice how there’s a slight performance hit? Now if I turn Avatar Imposters back on, it raises back up. This is because by having to render these further avatars, and thank you to [INAUDIBLE] for the explanation, then using less cycles like that results in a performance gain. And if you think avatars are becoming blocky too close, this is precisely because Avatar Mesh Detail it correlates. So by high it means avatars become imposters at further distances. If you want a greater performance boost set Avatar Mesh Detail to low and avatars will become imposters at nearer distances. So again it’s a trade off. Do what’s best for you. Notice now he avatars that are nearer look somewhat blocky, however I’m experiencing a performance gain. And then remember, turning it off will slow down performance. This works great on a lot of systems, however if you have older, unsupported Intel integrated graphics card, it’s probably best to turn it off. You may experience some artifacts or other weirdness. And that’s in line with what I recommended before. There’s a lot of crazy sounds here. So remember, the power is really in your hands. Avatar Imposters is great with crowd scenes. Keep it on and if you want people to become imposters at further distances then set it to high. Let me go back in there to the club to demonstrate. You can tweak any of these just about any time you want. If custom is off, then of course it’s simple but it’s good to get an understanding of then you can fine tune your experience and maximize your enjoyment of Second Life. If you consider all these options and what each one of these does, and you learn time by observation just by seeing what each one does and of course, watching this video, thanks for watching, you’ll clearly gain a better knowledge and feel more confident about using stuff. So that’s the Graphics Preferences in Second Life for you. I hope you’ve had a good time. There’s certainly more things to cover, like I mentioned in Advanced there’s additional hidden options, and over time we’ve optimized this. Like before it used to be three tabs and now it’s one, making it simpler. I’ve been Torley Linden. I’m going to see what else is going on here. I see they’re using Glow and some other techniques. All these things put together comprise what you see and enjoy in Second Life. Thanks for watching this video tutorial. Please rate, comment, favorite and subscribe to my videos on YouTube if you like them. It helps them grow. And if you have any questions and comments for me, go ahead and email me. torley@lindenlab.com I’d be glad to hear about your video tutorial curiosities and inquisitions, not in the bad sense, and queries. And I have stepped into the glow and I’m going to, so-called, duck out for now.

Version 3 - A3UI2KBKDG6U3K

Torley Linden: Amicable salutations! It's me, Torley Linden, of course! And, oh, I've gone shopping it seems, thanks to Tutu Clarkson [sp],who made this avatar. If you're wondering where are the watermelons? Look closely, there's green and pink right there and there's more melons. Anyway, let's get started. In today’s Tip of the Week, I'm going to cover the Graphics Preferences, what you need to know. A guided tour showing you what just about everything in their desk. Follow me, let's come along. Edit Menu and Preferences and Graphics - now by default, it's a simple slider and, normally, if you click at Recommended Settings, it will optimize depending on your hardware. If you have supported hardware--and I highly do recommend that--meet the system requirements or meet the system recommendation is even better, then you should be able to enjoy all of the Graphics Options in their glorious entirety. Otherwise, you may not be able to turn some of them on. I also advise you to upgrade your graphics drivers to the newest stable versions, whether you're an Invidia or ATI. Now, enough of that talk, there's time for more show. So Custom, this button, it enables all its options under here because, normally, you can one-click set it. Like you set it to mid, for example; set it back to low, and Custom will give you more granular control. There we go, a lot of options, and you may say, “Oh, my gosh! This looks complicated.” Well, there are a few simple principles which you should remember. For example, slide your [xx] to the left will mean that they are faster, the performance will be faster and the quality will be less. Such as Mesh Detail Objects, you turn left, it will be low; to the right, it will be high. This principle is true for all of them. Generally also, checking things would turn on Options and make things slower with some exceptions such as Avatar Impostors--which I'll show you later, it's one of my favorites--Viewer Optimizations boost your frame rate. OK, so let's start right here at the Shaders part, that’s a nice starting place. Bump Mapping and Shiny - we never move this in the future just so that everyone can turn on. So if I'm going to res [sp] a queue right here, with that off, Zoom in, Texture, Shiny. See? It does nothing. But, when I turn this on, now it has shiny…I move my camera, shiny, shiny, shiny. You can set the shiny high and the bump mapping refers to this bumpiness. We don’t yet have support for Custom bump maps, normal maps, but we will hope to in the future with Materials. That’s our keyword for having a versatile system of objects that can--woo!--get beyond this. But right now, you see, you can add extra depth; make it look more 3D with this bump maps. OK, so you can combine those and it looks pretty cool that way. The sky is not supposed to be white that way. I think there's something buggy with that. That supposed to blink on and off. That is, though, because I don’t have Basic Shaders even on. If I'm going to turn Basic Shaders on, then the world--let me just close that--it’s going to look more beautiful. So let me just angle up there and then turn Basic Shaders. OK, there should be subtle differences and the terrain should also get sharper. By the way, if the terrain looks blotchy, set it to high. See? Crisper detail right there. This would normally be great out on high ranking configurations. When I turn on the Basic Shaders, there we go, you see right there where the water. The water looks nice already. See? Notice when it's off, ooh, the water is like inky, then when on, oh, it's going to get better. Things going to get better and better all the time. OK, now, Atmospheric Shaders - if you’ve heard of Windlight, that’s the codename for our atmospheric rendering technology providing physically, accurately modeled lighting effects and atmospheres and environments. Woo! So, when I turn this on, notice the sky. It’ll light the ground. It will have greater dynamic range. It’ll just look more realistic. Put it that way and the skies will have nicely clouds and stuff. Yes! There we go. See? So now, you got this. It's more noticeable at day and sometimes [xx] was to go to World Menu, Environment Setting and Sunrise. OK, note how the sun looks. Woo, beautiful, beautiful, beautiful. And if I turn off those shaders, then it’ll look more beautiful. The cloud has gone away, I mean, it’s just fading out. Ah, it's not supposed to turn like a white like that. Oh, there we go. Yes, it's kind of pale. Hm, it's flashing at me. That seems buggy, but I will just turn it back on. If you can possibly turn that on, if your GPU graphic card has DirectX9 or higher, the Shaders support, you should be able to. And next, Water Reflections - this does what you think it should do. However, it is rather taxing and may cause a severe performance hit depending on your system. On higher systems, not so much, but the best way to find out, try it. Ooh, I hear the sound of dropping boxes or something. Let me go back to midday and I'll turn it on and off to show you. So I'm with the waters, and we don’t have reflections over the water, it looks quite nice. So I turn them on. OK, that was a subtle change. Did you notice that? If I put something over the water--oh, this is probably very recognizable. OK. Oh, it has labels. OK, so terranian trees, this means Linden trees, not Resident created ones out of prims. So notice those can be reflected. But static objects, you can move these go up successively and then you start to turn on extra details. Let me get my avatar on top of the water so you can see. And actually, what I can do here is I can go to World Environment Settings in Environment Editor. I want to change the water and make it glassy. That way, you can easier see the reflections, that’s glassy, like feel of glass. OK. Now, I would turn on all avatars and objects and there, there you see? My avatar reflections, before I was a vampire or something like it, but now I'm not. See? Then it adds that. So terrain, all static objects, all avatars and objects, and now everything. Everything has a benefit also of--you may not have noticed the difference there, but if there were things like particles, that would have shown up. Oh, let me show quickly, actually there's a particle. I think there's a waterfall, not a wayfall; waterfall particle system. We just quickly do this, don’t mean to rush you but just to show you a quick demonstration. I know you don’t have a lot of time sometimes and want to get this information nice and quick. Let me just copy that, just paste it in there. Oh, it's going slow. That’s not my library. It's confusing (hums). It's kind of moving slowly. There we go, there we go. OK, so waterfalls. Right? I mean, waterfall particle, this is just a particle system. It's a [xx], it's a fine mist and we put it over the water like that. OK. And then as you can see, the particles were also reflected. Normally, if we don’t have that [xx] thing, then they're not going to be. So that’s extra detail. Sometimes there's things like night, I think, let me just check this to. Yes, you notice the stars, if you look very closely, the stars were also reflect in the water. It's kind of hard to see that but it's beautiful! That's what you need to be, beautiful. OK, well, before we--Avatar Impostors is right there, the tour of force here. I’ll get to that, I promise. Draw Distance - how far you can see off in the distance as it says. You turn this up higher and it’ll let you see farther. So 64 is the lowest, and you crack it up and you can see farther. You know, there's these trees and there's going to be other things. Keep in mind, the higher you set it, the slower Second Life will be because it’ll need to render all these objects. And if you're looking very far way away, that’s going to be a lot more resource usage--oh, it's [xx]--but you see, there's these parts of buildings appearing here. Slide it back down. Usually, 128, 192 is typical. See how it works for you, though. That’s what it does, though. Max. Particle Count - oh, that’s a good one because we have a particle in the middle right here. You can control how many particles you see on screen at one time, too many maybe so called “laggy.” So if you turn them all the way off, you're not going to have any. And if you turn all the way up, then you're going to see more on the screen at one time. Typically, you can set this at about 4,096, that’s the typical number. Post Process Quality - OK, what is that? And by the way, there's this question mark here. You can always click this to get help. So like it says, “Sets the resolution with which Glow is rendered.” Now, let's have a look at Glow. Right click and I'm just going to drag this up. Now many of these graphics options are within the Texture tab, and Glow is, too. So I can set Glow. OK, you can see it's glowing. I'll just move this little card spinner, this [xx] here, and then I can set it to high. Let's see if that makes a visible difference for us. Maybe it's easier for us to see this in the dark since it's glowing, OK, or maybe not or we can set the glow higher. Let's see, Glow to high. There's so many settings there. Yes, there's a saddle [sp], it's the saddle. So see how that goes for you. Mesh Detail - so I'm looking at a detailed mini-map of sorts. It's not the same as this mini-map but it's right out here in the open. It's got a sculpted prim. It's got a fair amount, a very small and detailed geometry. So this is a good candidate for Preferences and the Mesh Detail Objects because when I set it to low, it will reduce the number of polygons. Which means objects will look crappier but they won't impose as much of a rendering burden. Notice that? OK, so now, they look very, very--they don’t look the same as before, and notice how the round things, they look more like kind of hexagon platforms. When we scale it up to maximum, to high, then it gets better looking. And sometimes, stuff may still look residually artifacted. I mean, they're created like that, so move your camera in and out to adjust that. Low, high. So that’s what that does. Flexy Prims - that is--OK, let me get a flexy prim here. I haven’t noticed, I think there may be a bug with this which she doesn’t work unless that was fixed like create or something. Let me create a flexy prim. Stretch out this prim. I love giving you illustrated examples and stuff. And in the Features tab, you know, it's right here, Flexible Path. This makes it all wiggly, wiggly prim. OK, we can quite see the wigglyness yet. Let me just drag it up and I'll get wiggly, when I start wiggling at, oh, wiggles. Now, notice it's literally a flexible prim. This likely has an effect when there's a lot of them on the screen at once where it should and then it controls the smoothness of how they wiggle. I'm going to make a few more. They're kind of like those wavy tube men guys you see at some used car sale places. OK, let's see. I'm just cropping a whole bunch. I mean, I'm going to clean up after. I'm not going to be bad about this. A lot of this. OK. So then we can wiggle them. Let's see if makes a difference though, that’s what I came here to show you. OK. So they're kind of smooth, they're moving slowly. Let's see if we move to high if that makes a difference. To low. Well, it doesn’t seem to be much of an apparent difference [xx] reported as a bug, this will be a problem. Let's move on. We are here at Linden World Lobby. Trees, trees, the magical fruit or something like that. Tree Mesh Detail controls the detail of Linden trees. And how do you if it's a Linden tree? Well, probably the easiest way is just to right click and edit. And if you notice, these are grayed out, then it's a Linden tree. You can't script a Linden tree and they have a number of limits. They're strange that way. Also, it doesn’t glow, notice like other objects. At the tutorial, on to trouble with Linden trees. But anyway, so if you notice, if I move to low, from farther distance, they're probably going to look more like cardboard cutouts and when I move it to high, they should become richer. Yes, yes, see? It's kind of inconsistent sometimes, but notice, “Low,” “High.” Low, they look really anemic, they look just like flat. And then high, and of course, high will make them render slower, too, as you get closer. (Hums). Avatars - this would probably be a good one for crowded place. I'm just teleporting from scene to scene here. Let me go to a place where there's lot of avatars and see if what we can show you what does that. Actually, avatars used in correlation with Avatar Impostors, that will be useful. So let's save this one for a little bit later. Terrain - yes, this is a good one for a bumpy place. I should show you somewhere that has--even this would do actually, some place with curves. So when Terrain Mesh Detail is low, the terrain may look more jagged; it's not going to look as organic and flowing. When it's high, notice, do you high or low, high or low, this becomes most apparent at mountains. Let me show you a good mountain range for that. Mountain range, found and located. OK. Notice terrain has a label of details, meaning when you zoom in, of course, it gets more detailed, more roundy. But when you're off like this and Terrain is low, it looks like a Noddy’s video game. So when I make it to high, notice? Better. Low, high; low, high. By the way, you going to ask and I should cover this in the future video tutorial, in Advanced Menu and Debug Settings here, there are a bunch of things which will enhance the quality in addition to this power user tweak it. So for now, I'm just kind of show you the basics. Of course, you can watch that later. Low or high, low or high, they're like doing the dance. Oh, I like that song. Sky Mesh Detail - finally, of all these mesh details, it just makes the sky looks better, of course. If you set it to low, they're going to look blockier. This is most noticeable with some types of suns, I think. If I set it to sunset--then let's go here. Triangles in the sky, low. See? Notice? So it's not so round, it's a little bit off. Then high; low, high; low, high. And let's see here. Let me grab a custom pre-setted. Some of my presets illustrate this really, really well. OK, I have a lot of them, don’t I? Oh, it's crazy. OK, I think this one has, yes. OK, notice how that blocky looks? It doesn’t look natural at all. Low, high; low, high; low, high. This can be pretty taxing, too, depending on your set up. So again, watch your performance. If things start to feel really slow, you can always go back. That’s pretty cool. Lighting Detail - oh, my gosh, you need to know about this. This is great. This is for what we call local or point lights. These are controlled through objects that are lit in the Features. Let me see here, I'll just go back to a normal--let me go to midnight, actually, that will be dark. And I'm going to raze [sp] a cube again as I often do and it features right here “Light.” This is what makes it a light prim. OK? And then I can zoom in, and it's not going to be lit up because lighting details only the sun and moon. But when you turn on “Nearby Local Lights,” and then it should pop open, I mean not pop open literally but you should see there's a light here. And you can change the color of the light to different things. Important consideration, however, only the six nearest lights to your avatar you're going to see. This is due to an open geographics [sp] protocol limit. If you’ve got more than that, you're not going to see them in case. So if you notice, there's three. And then there's three…I wonder if we can make this line, just one at a time. Well, they're all green. You can see they're clearly emanating lights, so six. However, notice if I make another three--oh, see? The ones in the middle, they don’t have lights right now because they're not selected. But when I deselect, only six nearest to me are going to be lit. Just like that, see? And when I move these ones closer to me--my avatar right there--then these ones aren’t going to be lit. So keep that in mind, if you're wondering, Oh, darn it, I crashed. Oh, my gosh. Pardon about that. After the crash, my preferences and graphics here were reset, but that’s OK. I can keep illustrating various principles. Hardware Skinning - you should generally turn this on if you can. If you're on an older hardware that’s unsupported, this may cause problems. There's a probability of that. What it does is it's a slight acceleration for your avatar rendering. Turn it off if you think you're doing stuff, and once that’s on, notice that Avatar Cloth is also enabled. Avatar Cloth means that you have something like--notice Avatar Mesh? Let me--my gosh, this is a lot of boxes, let me just turn these off. Now, I look so naked. It's not technically, you know. That’s weird. So if you're wearing mesh clothing and your appearance is--keep in mind like a mesh skirt--this will be a mesh shirt right under here. Or not a shirt, I mean, skirt. Then Avatar Cloth, when Cloth is on, it means it will ripple. OK, let's see. Let's see an example of that. It's off, so it's not rippling. It's not rippling in the wind when I fly. But when I turn it on, this has an extra touch--maybe nice, maybe this graphic. So now, Avatar Cloth is on. And now notice, look very closely, there's some rippling action there. Very subtle, look at that. Oh, you didn’t mean to see that. OK, see? It's kind of like my buttocks there are rippling. (laughs) It has a good effect. It's noticeable with longer kinds of coats. Next stop--and remember, a good guideline is if you're confused, you can just click one of these and then with Custom open, it will show you all the details that went into making that. So you cay say, “Hey, OK, I know what this is roughly equivalent to in what settings specifically make up the high setting versus the midsetting,” for example. Then you can compare and say, “Hm, OK, I want to tweak this. This will be better to taste.” If you want to go all the way pig out on your graphics buffet, then Ultra is the way to go. And speaking of Ultra, in a way and a matter of speaking, Hardware Options. This has additional options above this which may increase quality even more. Click that button and this will come up. Filtering, Anisotropic Filtering. You're like, “What the heck is that?” You can look it up on Wikipedia, the long story short, objects with textures at oblique or not right on angles, they will look slightly sharper. This may be kind of hard for me to show because of the video, when I recorded the video, there's some deterioration in it's fine details. But you can compare it on and off. Try and make some objects that are in the far distance and have textures like see a sign with text on it. Antialiasing is more [xx], we added this recently. This is good because before, you had to go to your Graphics Drivers Preferences. Now, the big thing about antialiasing is it smooths out jaggies. If you think Second Life looks jaggy, you can turn this up. I can go up to 16, it depends on your graphics hardware. You may not be able to attain this, some can go even more than that. But if you disable--let me see if I can show you this. This is one of the biggest determinants especially if you take photographs--lots snapshots in Second Life--this will impact the quality of those. So let's see here. OK, you can see the edges. Look at the fine edges of this [xx] thing, and let me turn off. OK. So when I disable it and OK, the screen will black for a while and it will take just a moment to switch resolution as it says. OK, just give that some time and hope it doesn’t kill me. There we go. And notice--look, I'm going to zoom in obviously on this, there's jag here. You can see its jaggy here. Hardware Options and make it back to four. OK. And now, smoother, so play with that, the higher the better. What antialiasing does, it renders a scene the number of multiple times than it actually shown and it scales it down. So obviously, it can slow things down, but for the price you're paying, it can look very nice, make in Second Life look nicer. OK, now Gamma, this and Fog Distance Ratio are great out. Now, the reason why is because--let me go back here--Atmospheric Shaders overrides them, with controls of its own. If I were to disable that Atmospheric Shaders again in Hardware Options, you'll notice I can set my Gamma. I don’t find it too useful. And Fog Distance Ratio, this contains basically how much fog is. If you set it to low, then things should look foggier. Yes. But it doesn’t really work too well. It's only the trees are foggier there. I think that’s kind of broken, it's not working the way it should. So I don’t really bother with that, I just keep Atmospheric Shaders on. You probably want to keep it usually far so that things don’t look weird like that. Texture Memory - this is the one we autodetected to how much you have on your graphics card. If you have like SLI or ATI’s Crossfire, there's sometimes, some occurrences may autodetect wrong. In which case, you can override it. I personally have not noticed a big difference between setting it, say, lower and higher that much. You don’t want to set it tremendously low because then, you'll probably going to end up with flickering textures because they all can't get loaded in memory. I'd say, you set it to 228 and up, typically, but see what works best for you. This really depends on your specific hardware. This is why we let you override it. In the past, we didn’t. Ah, yes, OK. We got to get to Avatar Impostors. So let me find a club with a lot of people. To the club [xx] club we’re here. Now, notice how some of these avatars, they're animating less smoothly and they look like they have sort of fringy edges. This is because Avatar Impostors is on. Avatar Impostors is a pretty cool feature. You may ask, “Why would you want to impostor someone? What does it literally mean to fake someone out like that?” It means avatars in the distance are going to be drawn representationally like a 2D cardboard cutout. Think of old Nintendo games where someone had a two-cycle walk. So it means they're going to be animated and look somewhat less smooth. The trade off is a performance boost. I can exhibit this--and I've shown this before--but let me show you here today since you're watching this, View Menu as Statistics Bar. Let's compare this basic frames per second. This is 10, it's OK. If I turn Avatar Impostors off, now it should slow down noticeably. Yes. Notice how there's a slight performance hit? Now I turn Avatar Impostors back on, it raises back up. This is because by having to render these further avatars--and thank you to [xx] Linden for the explanation--then using less cycles like that results in the performance gained. And if you think avatars are becoming blocky too close, this is precisely because Avatar Mesh Detail, it correlates. So by high, it means avatar has become impostors at farther distances. If you want a greater performance boost, set Avatar Mesh Detail to low and avatars would become impostors at nearer distances. So again, it's a trade off. Do what is best for you. Notice now avatars that are nearer, they look somewhat blocky. However, I'm experiencing a performance gain and, remember, turning it off will slow down performance. This works great on a lot of systems. However, if you have older, unsupported Intel integrated graphics card, it probably best to turn it off. You may experience an artifacts where other weirdness and that’s in line with what I recommended before. There's a lot of crazy sounds here! So, remember, the power is really in your hands. Avatar Impostors is great with crowd scenes, keep it on. If you want people to become impostors at farther distances, then set it to high. Let me go back in there in the club to demonstrate. You can tweak any of these, just about anytime you want. If Custom is off, of course, it's simple, but it's good to gain understanding of what each one of these does. Then you can fine tune your experience and maximize your enjoyment of Second Life. If you consider all these options and what each one of them does, you learn to by observation just by seeing what each one does and, of course, watching this video--thanks for watching--you'll clearly gain a better knowledge and feel more confident about using stuff. (laughs) So that’s the Graphics Preferences in Second Life for you. I hope you had a good time. There's certainly more things to cover like I mentioned in [xx] additional hidden options and overtime, we've optimize this. Like before, you use three tabs and now it's one, making it simpler. I've been Torley Linden. I'm going to see what else is going on here. I see they're using some glow and some other techniques. All these things put together comprise what you see and enjoy and experience in Second Life. Thanks for watching this video tutorial. Please rate, comment, favorite, and subscribe to my videos on YouTube if you like them, it helps them grow. If you have any questions and comments for me, go ahead and email me, Torley@LindenLab.com. I'd be glad to hear about your video tutorial curiosities and inquisitions--not in the bad sense--inquiries. Woo, and I have stepped into the glow and I'm going to so called “duck out” for now. Stay tuned for more video tutorials.
