AMD releases Catalyst 7.5 graphics drivers

A new set of Catalyst 7.5 drivers is now available for users of AMD's ATI Radeon graphics cards. The drivers are available for Windows Vista x86, Windows Vista x64, Windows XP, and Windows XP Pro x64. According to AMD, these drivers significantly improve OpenGL performance in Windows Vista:
OpenGL performance in Windows Vista improves on the Radeon X1950 XTX at high resolutions (1920x1200 or greater) with anti-aliasing and anisotropic filtering enabled. Doom 3 and Quake 4 improves as much as 13-18% .and Prey improves at least 15.6%. The Radeon X1950 Pro and Radeon X1650 XT also see improvements in Doom 3 and Quake 4 up to 14.1% at higher resolutions with anti-aliasing and anisotropic filtering enabled.
The Catalyst 7.5 release also brings DirectX 10 support to users of Radeon HD 2900 XT graphics cards (in either single-GPU or CrossFire configurations) running Windows Vista x86.

As always, a number of bug fixes are on the menu for these new drivers, and those are detailed in AMD's release notes. In Vista, AMD has fixed bugs in Doom 3, Quake 4, IL2 Sturmovik, Lego Star Wars II, and Serious Sam. And in Windows XP, bugs in Call of Duty and Just Cause have been chased down and resolved.
