AMD apparently chose to wait until Windows 7's launch to release its latest batch of Catalyst graphics drivers. The Catalyst 9.10 driver set is now available from AMD's Game website for Windows XP, Windows Vista, and Windows 7 in their 32-bit and 64-bit variants.
According to the official release notes (PDF), that's pretty much all you can look forward to—well, that and bug fixes. AMD does note that the drivers support the Radeon HD 5000 series' new supersampling antialiasing mode, too, but that functionality was also available in beta Evergreen drivers.
Catalyst 9.10 bug fixes cover AMD's Catalyst Control Center, Tiger Woods PGA Tour 08, Ghostbusters: The Video Game, The Chronicles of Riddick: Assault on Dark Athena, Combat Mission: Shock Force, and other miscellaneous little issues. See the full release notes for details.
Update: As far as we can tell, these drivers don't support Radeon HD 5750 and 5770 graphics cards—only the Radeon HD 5800 series and older products.
