3DMark2001 SE Gaming Tests
The tests ran at 32-bit texture color and frame-buffer depths; Z-buffer color depth equaled 24 bit. We used dual buffering and Pure Hardware T&L mode.
Game 1: Car Chase
There is a certain element of randomness in Game 1 scene that is why the results are quite diverse. The situation is aggravated by the fact that the CPU and the overall system performance do affect the results in car Chase a lot. Nevertheless, the tests with forced full-screen anti-aliasing allowed us to make a few conclusions.
First, NVIDIA GeForce FX 5900 Ultra is enormously faster than GeForce FX 5800 Ultra when tested with enabled anti-aliasing. ATI chips also outperform GeForce FX 5800 Ultra though not that greatly, because of a little bit lower memory bus bandwidth than by NVIDIA GeForce FX 5900 Ultra.
Second, the results gave us to understand that all Direct3D anisotropic filtering optimizations work for NVIDIA GeForce FX family only in Performance mode, and these are most likely to be the optimizations based on scene geometry analysis. Replacing tri-linear filtering with a combination of bi-linear and tri-linear filtering doesn’t make much sense in 3DMark2001, because this test set doesn’t use any tri-linear filtering at all, and textures clearness analysis works only in OpenGL so far.
