Even though contemporary visual processing unit offer truly admirable performance and capabilities, benchmarking wars sometimes force designers of graphics chips to perform certain tweaks to get additional speed. Sometimes those tweaks degrade image quality, and while the majority of users never notice those slight degradations, demanding customers complain about them.

3DCenter and nV News web-sites have found that NVIDIA’s latest GeForce 7800-series graphics processor has lower quality anisotropic filtering (AF) compared to predecessors, which contradicts to what NVIDIA said about its latest chip.

“The G70, delivering a texel power of more than 10 Gigatexels, but using 2x AF for some angles only–while the user enabled a mode called "16xAF"; plus the tendency to have textures which tend to shimmer, is an evidence of the G70's incapacity,” 3DCenter web-site notes.

NVIDIA has admitted the problem and said it would fix it. By now NVIDIA has posted a beta driver that may fix the issue for at least certain games.

“We have isolated the problem and we are working on the fix. We will also be working on a fix for the application profile problems that some users were experiencing. We hope to have a fix soon,” said Brian Burke, a spokesman for NVIDIA Corp.
