TweakTown tested the latest ATI Catalyst driver, you can check out the performance overview over here.
"This popped up a little out of nowhere. To be honest with how late we got the 11.10 Catalyst drivers from AMD last month, I'd figure we'd probably be getting these ones at the last minute as well. At the same time, it doesn't surprise me too much, though, that we're seeing them in the middle of the month.
No doubt AMD don't want to get into a pattern of releasing them at the absolute last minute of the month, especially more so with the next driver coming hopefully before Christmas next month, ideally before the 17th when I take my first holidays for the year."
