AMD released its latest "performance driver" for Radeon graphics cards, the Catalyst 11.11a. With this release, AMD is using the term "performance driver" to refer to performance-enhancing Hotfix updates it launches between its scheduled monthly WHQL-signed updates. Catalyst 11.11a fixes some outstanding game-related bugs and improves performance and resolves driver-related bugs for a variety of recently-released titles such as Batman: Arkham City, Rage, The Elder Scrolls: Skyrim, and Battlefield 3. The rest of the driver is based on Catalyst 11.11.

A list of changes follows.

AMD has now released the CrossFireX Catalyst Application Profiles 2 for their latest 11.11 WHQL drivers. The improvements apply to just two games:

New profiles added to this release:

- Saints Row 3: Resolves stuttering seen when playing in CrossFireX mode. Also provides Single GPU and CrossFireX performance improvements when running in lower resolution configurations
- Gothic 4 Arcania: Fall of Setarrif: Improves CrossFire performance

There's nothing yet for hit game The Elder Scrolls V: Skyrim in this release, unfortunately. CAP 2 can be downloaded here.

Well, this 11.11 release doesn't list any performance improvements unfortunately. It contains just one new unexciting feature and a few fixes, but still has quite a long list of known issues. The new feature is Adobe Flash Player 11 hardware accelerated graphics support, including the A-series and E-series APUs. Fixes include things like Rage texture corruption, bezel compensation working correctly in Far Cry 2 and a screen tearing fix for displays in clone mode. Therefore, if your setup is working fine, there's no rush to update to this driver in case it breaks something. Note the following CAP 1 profile updates added to this release:

- Battlefield 3: Tweaks to the CrossFire profile
- Global Ops: Commando Libya: Improves CrossFire performance
- Driver San Francisco: Disables CrossFire
