VGA Testing Methodology
At the start of all tests, the previous display adapter driver is uninstalled and trace components are removed using Driver Cleaner Pro. We then restart the computer system to establish our display settings and define the monitor. Once the hardware is prepared, we begin our testing. The synthetic benchmark tests in 3DMark06 will utilize shader models 2.0 and 3.0, while the video games will use their own proprietary game engine. For lower-end VGA products we test at 1024x768 (15-17" standard LCD), 1280x1024 (17-19" standard LCD), and 1680x1050 (22-24" widescreen LCD). In our higher-end VGA product tests we conduct add the 1920x1200 (24-28" widescreen LCD) resolution. In some tests we utilized widescreen monitor resolutions, since more users are beginning to feature these products for their own computing.
Each benchmark test program begins after a system restart, and the very first result for every test will be ignored since it often only caches the test. This process proved extremely important in the World in Conflict and Supreme Commander benchmarks, as the first run served to cache maps allowing subsequent tests to perform much better than the first. Each test is completed five times, with the average results displayed in our article.
Our site polls and statistics indicate that the vast majority of visitors use their PC for playing video games, and practically every one of you are using a screen resolutions mentioned above. Since all of the benchmarks we use for testing represent different game engine technology and graphic rendering processes, I feel that this battery of tests will provide a diverse range of results for you to gauge performance on your own computer system. Since most gamers and enthusiasts are still using Windows XP, it was decided that DirectX 9 would be used for all tests until Microsoft offers Windows 7 to replace the Vista.
