Nvidia caught "over optimising"

WE CALL IT optimisation these days, but what do you call it when a firm over optimises? We used to call it something different in the days of the NV30, when Nvidia had to do something to make its chip work better and do better in benchmarks but to our surprise it seems to have done it again. The chaps from 3D Center, a very talented in-depth site, spotted and tested and proved that Nvidia is using a lower anisotropic filtering quality than any other card available.

Those guys noticed a texture shimmering problem when you are using normal driver settings. This was the case with NV40 cards but you could resolve this flickering by using high quality driver settings. This won't work on G70 based cards, so the guys well known for its thorough benchmarks went digging a little deeper into the chip.
