VGA Testing Methodology
As of October 2009 Benchmark Reviews has discontinued testing on the Windows XP (DirectX 9) Operating System, although it is recognized that 52% or more of the gaming world still use this O/S. DirectX 11 is native to the Microsoft Windows 7 Operating System, and will be the centerpiece of our test platform for the foreseeable future. In many tests, DirectX 10 is utilized on the Windows 7 platform.
According to the Steam Hardware Survey published at the time of Windows 7 launch, the most popular gaming resolution is 1280x1024 (17-19" standard LCD monitors) closely followed by 1024x768 (15-17" standard LCD). Normally, our benchmark performance tests concentrate on the up-and-coming higher-demand resolutions: 1680x1050 (22-24" widescreen LCD) and 1920x1200 (24-28" widescreen LCD monitors). These resolutions are more likely to be used by high-end graphics solutions, such as those tested in this article.
In each benchmark test there is one 'cache run' that is conducted, followed by five recorded test runs. Results are collected at each setting with the highest and lowest results discarded. The remaining three results are averaged, and displayed in the performance charts. Due to the unique nature of this card, we're using two test applications (Crysis Warhead and Far Cry 2) to test the performance of the GTX 275 GPU, and two other applications (Batman: Arkham Asylum and the Darkest of Days demo) to evaluate the performance of the card when PhysX is used.
