The Windows XP desktop was set to 1280x960 with a 32bit color depth and 85Hz refresh rate for all tests. Refresh rate locks for 3D graphics modes, as supported by both NVIDIA and ATI graphics control panels, was not enabled. V-Sync was forced off via the graphics card control panel as well. For the NVIDIA cards "High Image Quality" was enabled. All other graphics card control panel settings for the ATI cards were left to their default settings.

Anti-Aliasing and Anisotropy were applied in the game engine where the options existed. For games that did not support those options natively, the graphics card control panel was used.

Custom batch files were used when possible for automated benchmarking, which are available upon request. When manual benchmarking was necessary Fraps was used.

Benchmarking was done with Windows set to the "Adjust for best performance" profile and all unnecessary Windows services and hardware devices were disabled. The latest drivers for each necessary hardware component were installed prior to testing and kept consistent throughout.

Sound and networking interfaces were enabled for all tests.

Windows XP was installed fresh on two seperate but identical hard-drives prior to testing (one for the ATI system, one for the NVIDIA system).
