AMD Catalyst 11.11a Performance driver is out

AMD has prepared the Catalyst 11.11a performance driver for Windows XP, Vista and 7, you can download this new release over here. Included in the update are performance enhancements for Batman: Arkham City, Rage, The Elder Scrolls V: Skyrim, and Battlefield 3.

The CrossFireX issue with Skyrim hasn't been resolved yet, instead AMD decided to disable CF in this game to prevent issues with negative scaling and image quality. Terry Makedon posted on Twitter that Skyrim CF will be fixed asap in an upcoming driver update.
