Ati Drivers: Performance
built 614 days ago
Disagree: ATi's new drivers (5.1) are massively buggy, and Nvidia still leads by a mile and a half in Doom 3. ATi's optimisations have been to use brilinear filtering - basically lower image quality, better performance. Considering that Nvidia got labelled cheats for doing that (and now no longer do it) that's a bit rich from ATi, who've now lost moral high ground both in dual-slot coolers and image quality.

Tweaktown has a couple of comparison benchmarks of the ATI catalyst drivers, which show very little difference between 7.5 and 7.6 in terms of performance. To be honest with you though, I don’t trust their figures that much so I would take whatever you see there with a grain of salt, but apparently the bug fix list includes a fix for dual monitors, so you should probably give it a shot Richard.
