AMD has released a new hotfix with performance optimizations for the freshly-launched Radeon HD 6850 and 6870. Improvements have been made for the Radeon HD 6800 series in Aliens vs. Predator, StarCraft 2, and OpenGL, which provides gains in Prey, Quake Wars Enemy Territories, and Heaven v2. Additionally, CrossFire has been tweaked for Metro 2033, F1 2010 (DirectX 9), Fallout New Vegas, and Dead Rising 2 (resolves negative scaling). Other bulleted changes include support for OpenGL 4.1 beta and Morphological Anti-Aliasing.

As with every Catalyst hotfix, AMD says it hasn't completed full testing on the update, so it's not officially supported. In other words, you're on your own if catastrophe strikes. It's also worth mentioning that the hotfix is only available for Windows Vista and 7 – sorry XP users. So, if you have a recent version of Windows and the intestinal fortitude of a bull, go ahead and grab your copy here.
