Quake 4

Quake 4 is another game that lowers performance because of high-quality AF noticeably. At the same time, the GeForce 7950 GX2 does not lose any significant amount of frames per second because of the lack of texture filtering optimizations.

Serious Sam 2

Given that Serious Sam 2 is very dependent on performance of texture units, disabling trilinear filtering optimizations decreases performance of Nvidia hardware by up to 24%, bringing the speed of the GeForce 7950 GX2’s 48 texture units to in-line with Radeon X1950 XTX’s 16 texture units. It is interesting to note that high-quality anisotropic filtering does not cause performance declines
