"There is another important issue here, of course, and that's trust. Yes, the API provides a little wiggle room, but NVIDIA is flaunting the situation in multiple and evasive ways in order to make its products look better than they are. All indications are that NVIDIA deceived reviewers—and by proxy consumers, investors, and PC makers—when it told them the 44.03 Quality setting would do away with the funky "lightweight" trilinear method, then enabled that method on a per-application basis anyway. They dug the hole deeper when they claimed a 30% performance increase in UT2003 on the GFFX 5600. And this all happened at the same time as they were concocting multiple methods of inflating scores in 3DMark03 while waging an all-out PR assault on 3DMark's creators. I would think twice before putting my hard-earned cash down for an NVIDIA product in the midst of all of this deception."
