I can't confirm how much this affects frame rates, but to some extent it must help with even a few FPS in benchmarks. It was odd to notice that they tested these results using American McGhee's Alice. I wonder how an updated OpenGL engine would be affected.

The Control Panel allows the user to disable all the "optimizations” concerning the anisotropic filter - but now it's obvious that these options only affect Direct 3D and not Open GL. Disabling the "optimizations” and setting "High Quality” still results in shimmering textures in our tested games (American McGee's Alice and Prey). The Riva Tuner shows why: the OGL filtering restrictions are still active, as shown on the pictures beneath.
After deeper testing we came to the conclusion that the Forceware 93.71 WHQL is the last official driver whose Control Panel affects Open GL. Starting from version 101.09 (unofficial beta) up to 169.2x the "optimizations” stay alive, no matter what's set in the CP. If you want your Geforce to filter properly, you have to use 3rd-party tools like the Riva Tuner or Nhancer.
Nvidia is informed, we're currently waiting for a statement.
