3Dmark03 measures performance by simulating games written to DirectX 9, which are contemporary games. We run this program in three resolutions, 1024x768x32, 1280x1024x32 and 1600x1200x32, first without antialiasing and anisotropic filtering, and then configuring antialising at 4x and anisotropic filtering also at 4x. This improves the video quality but lowers the performance. We were willing to see how much performance we lost by putting the VGA to run at the maximum possible image quality. It is important to notice that ATI chips can run at 6x antialiasing. Since nVidia chips cannot run at this configuration, we had to use 4x antialiasing to use a configuration that is valid to all video cards included in our bechmarks, allowing direct comparison between them.
