Initial Impression: Owners Nv40 line of graphic cards will be quick to notice that these cards are very configurable in regards to anistropic filtering and texture filtering, The modes include, High Performance, Performance, Quality, and High Quality, Included into these modes is the ability to turn off trilinear optimizations and anistropic filtering optimizations. The purpose of this analysis is to help the Nv40 users sort out which modes are usable to them and which are not.

Conclusion: Does anyone remember the Geforce 2 days? There was one setting for anistropic filtering and thats all we used. Tweaking modern day graphic cards can be a chore. With all the buzz circling the latest trilinear optimizations going on in graphic cards Nvidia has stepped forth and allowed users the ability to disable them. Nvidia currently offers the most tweakability with its image quality settings. Die hard image quality freaks and performance enthusiasts alike will easily be able to find a setting that suits them.
