By means of the new " optimized " ATi driver this however definitely no more is given. ATi reduces simply the image quality, in order to stand there in bench mark better.A picture's worth a thousand words, and 3DCenter has a few nicely screenshot comparisons with and without ATI's optimizations. Definitely check this one out, the pictures alone make quite a compelling case. Thanks to the OCP for the tip.
Update: See this article at the FiringSquad for a detailed explanation of the issue. They're going easy on ATI, but all the evidence is there.
