What causes lag?

A number of factors contribute to what we all know as 'lag':

Your computer spec
Your broadband/internet connection speed and busy-ness
The internet (in general) busy-ness
SL busy-ness
How much is going on in the sim you are in, e.g.
- how many avatars are nearby
- how many textures are visible
- how many scripts are running in the sim

Your can't do much about how many people are using the internet or SL at the same time as you, but what you can do is help your computer to work 'smarter'.

Steps to reduce lag

Graphics Preferences

Edit Preferences (CTRL+P)
Select the "Graphics" tab
If you are runnning at 'high' or 'ultra' settings, try reducing it to 'medium' or 'low'

If this doesn't help enough:

If "custom" isn't selected (checked), tick the checkbox to show the extra settings and sliders
Reduce the "Draw Distance" slider to minimum (64m)
Reduce the "Particles" to near minimum (eg 256 or 512) - you will still see some particles, just not all
Ensure "Avatar Impostors" is on (checked) - this makes avatars further away from you appear in less detail
Reduce any other sliders that you aren't using right now

e.g. when building or shopping you might turn up "Objects" and turn everything else down
when editing appearance or trying on clothes you would turn "Avatar" and perhaps "Objects" and "Flexi" up, everything else down
when terraforming you can turn "Terrain" up
when exploring, turn "Terrain", "Trees", "Flexi" and "Objects" up

The checkbox for "local lights" will display any localised light sources (such as 'spotlights' or face lights). Turning this off may also slightly improve lag, but it is a personal preference.

Other possible steps to reduce lag

Remove any render-intensive objects your avatar is wearing (such as sculptie hair, objects with 'bling', very detailed objects) or change them for simpler accessories More information
Edit Preferences (CTRL+P)
Select the "Network" tab, then "Clear Cache"
Re-log (log out and log back in)

Turning off any music or media playing in your SL browser may also help.

Computer enhancements to improve SL performance/reduce lag

Some small adjustments or spend on your computer may improve SL performance:

Turn off any other CPU-intensive packages such as Microsoft Word or PhotoShop
Turn off any other internet-intensive programs such as internet radio or online games
Add more RAM - 2Mb is recommended for XP, 3Mb for Vista
Change your graphics card to a better one
Change your motherboard to a higher-performance one

(NB - it may be cheaper to buy a new computer than to change all the hardware above! ;-)

-First thing you can do to reduce the lag is going to 'Preferences' (CTRL+P).
-Then go to 'Graphics', lower 'Draw Distance' to 64 (minimum).
-If that doesn't help much, go to 'Network' tab, then 'Clear Cache'.
+==What causes lag?==
-After Clearing your Cache, re-log (log out and log back in).
+A number of factors contribute to what we all know as 'lag':
-Of course you can also lower some graphic options like Shaders, depends on your graphic card.
