AMD has released the latest version of its Catalyst graphics driver package for 32-bit and 64-bit versions of Windows XP, Vista, and 7. This version of the drivers introduces support for the Radeon HD 7800 series under Windows Vista and 7 - the 7700 and 7900 series cards were added in the last release, meaning that the Catalyst drivers now support the complete lineup of 7000-series cards. Windows XP support for these cards is slated to be introduced next month in Catalyst 12.4.
The new drivers also fix issues in a number of games, including a texture corruption bug in Skyrim that some of you mentioned was a problem with the 12.2 drivers. Other resolved issues include bugfixes in games like HAWX, Quake 4, XPlane, Alan Wake, and Far Cry 2, a crashing bug in the Furmark benchmark, and startup issues with the Catalyst Control Center.
The drivers support all Radeon HD 2000, 3000, 4000, 5000, 6000, and 7000 series graphics cards, IGPs, and APUs except where otherwise noted in the release notes, which are linked below. Support for the mobile versions of these cards is provided only to Windows Vista and 7 users.
