As it tends to do every month, AMD has released a new driver update for its Radeon graphics cards. The Catalyst 9.5 release has popped up on the AMD Game website, and you can download it right now for Windows 7, Windows Vista, and Windows XP in 32-bit and 64-bit variants.
Speaking of Windows 7, AMD points out that this unified driver release has "full WDDM 1.1 WHQL certified support" for Windows 7—at least as far as Radeon HD 4000-, 3000-, and 2000-series GPUs are concerned. Naturally, Microsoft's Windows Hardware Quality Labs have given these drivers their stamp of approval for Vista, as well.
Otherwise, the 9.5 Catalysts are supposed to improve performance in Company of Heroes and BattleForge by up to 10%. (The gains should only manifest in CrossFire X multi-GPU configurations for the latter.) AMD also says it has resolved "a number of issues" with the ATI Video Converter, although that application still requires Windows Vista and a Radeon HD 4800- or 4600-series GPU to work.
Normally, you'd be able to learn more about bug fixes and performance improvements in the official release notes (PDF). Despite the file name, however, that PDF currently seems to include the Catalyst 9.4 release notes.
