Torley's benchmarks

Context: In response to "Does the Viewer run faster on Mac OS X or Windows?", I knew one way of getting close is to have a similar setup on the same Mac hardware, then use Boot Camp. I had previously done anecdotal comparisons, but decided to followup with something more in-depth. Usual disclaimer applies that this is only my experience, YMMV but I've observed similar results on four Macs now. Keep in mind Second Life is ever-evolving and my conditions can't exactly be replicated because of how content will change and avatars will move in and out of a scene, but between reboots, I got similar enough situations to make this a more worthwhile comparison than nothing at all.

Config:

  • Second Life 2.1.0 (207030) Jul 16 2010 12:08:58 (Second Life Release)
  • CPU: Intel(R) Core(TM) i7 CPU 860 @ 2.80GHz (2793.03 MHz)
  • Memory: 8182 MB
  • OS Version: Microsoft Windows 7 64-bit (Build 7600) and
  • OS Version: Darwin 10.2.0 Darwin Kernel Version 10.2.0: Tue Nov 3 23:08:29 PST 2009; root:xnu-1486.2.11~3/RELEASE_I386 i386
  • Graphics Card Vendor: ATI Technologies Inc.
  • Graphics Card: ATI Radeon HD 4850
    • Windows Graphics Driver Version: 8.14.0010.0700
    • OpenGL Version: 2.1.9026
    • On Mac, OpenGL Version: 2.1 ATI-1.6.6

Setup notes:

  • Screen resolution is 2560x1440, iMac running in a maximized window.
  • On Windows 7, I installed Catalyst 10.7 drivers but had to roll back the Boot Camp 3.1 graphics drivers due to a color banding issue.
  • The iMac is still on 10.6.2 because 10.6.4 has known, sporadic freezing issues.
  • I chose the City Female Avatar from the Library.
  • I waited 5-10 min. for a scene to rez and the Statistics to stabilize. There's the known issue that textures don't always rez unless you move your cursor over them, but

Graphics Hardware

The usual recommendation is to use nVidia hardware for the best OpenGL support. This is a combination of the actual OpenGL functions, and the utilities to adjust the display. The DirectX labelling is mostly a guide to the available GPU power for the purposes of OpenGL use.

Many motherboards have built-in graphics hardware, which is, frankly, barely adequate. If your cash-flow is a problem, it's good enough to run SL, and you can add a graphics card later. Don't expect to get a high frame rate. The Viewer 2.x family seem to be setting graphics to get a higher frame rate, and if you're following this approach, you could find detail settings are low enough to be ugly--circles appearing as hexagons--and trading frame rate for a slightly higher detail setting may be worth it.

For an enjoyable experience, I holistically agree about skipping integrated (usually Intel) graphics and opting for a dedicated graphics card. I see a lot of GPUs that cost US$25-50 and more than exceed our System Recommendations — it's a worthwhile investment. - Torley-favicon.png on 2010-07-26 @ 1:11 PM Pacific
