A few days ago we received word from ATI about their new Catalyst 7.10 drivers which are supposed to bring a list of performance optimizations to the table. The drivers are available for both Windows XP and Vista in 32-bit and 64-bit flavors. There is no mention whether the optimizations are OS specific but looking at the list of games that are supposed to get dramatic speed-ups, there is a mix of everything from DirectX9 titles, DirectX10 and OpenGL.

Popular titles like Bioshock, Battlefield 2142, Company of Heroes, Enemy Territory: Quake Wars, FEAR, World in Conflict, are all getting substantial performance bumps according to ATI's release notes, from 10% to up to 80% improvements for both single card and Crossfire performance.

Should we even say you must try these? Just pick your OS and download:
