Anisotropic Filtering: Angle Off

To check out the best anisotropic filtering ATI’s and Nvidia’s solution can provide, we used the same screenshots from 3DMark as in the test of tri-linear filtering:

ATI Radeon X1950 XTX vs. Nvidia GeForce 7950 GX2 Trilinear Filtering Comparison

ATI Radeon X1950 XTX,
Catalyst AI: Advanced

ATI Radeon X1950 XTX,
Catalyst AI: Standard

ATI Radeon X1950 XTX,
Catalyst AI: Disabled

Nvidia GeForce 7950 GX2,
Texture Filtering: Quality

Nvidia GeForce 7950 GX2,
Texture Filtering: High Quality

Easy to see, the ATI High Quality AF algorithm is beyond competition here. It provides the best anisotropic filtering available today, which you can’t have on an Nvidia GeForce 7-series card.


Half-Life 2, ATI Radeon X1950 XTX on the left and Nvidia GeForce 7950 GX2 on the right.
The difference in anisotropic filtering quality on various angles is pointed at with arrows.

For your convinience we have included several clips too:

  • Battlefield 2 movie (download here)
  • Half-Life 2 movie 1 (download here)
  • Half-Life 2 movie 2 (download here)

    ATI High Quality AF ensures higher sharpness of textures at a long distance irrespective of the angle of inclination of a surface. This is most conspicuous in the first Half-Life 2 clip.
