AMD has released its Catalyst 9.12 drivers, bringing DirectCompute 10.1 compatibility to Radeon HD 4700 and 4800-series graphics cards, as well as support for OpenGL 3.2 extensions, performance enhancements and more.
Performance in 3DMark Vantage has been improved by as much as 9% on Radeon HD 5700 and 5800 cards, while the game S.T.A.L.K.E.R.: Call of Pripyat will run up to 6% better on single card configurations. Other applications mentioned in the release notes include PowerDVD, WinDVD, IL-2 Sturmovik: Forgotten Battles, Resident Evil 5, and Tom Clancy's HAWX.
Additionally, AMD has pushed out a separate Catalyst hotfix that allows multi-GPU configurations to work with Eyefinity display setups, introduces DisplayPort audio output capabilities, and adds "full support for GPU acceleration of OpenCL when used in conjunction with the ATI Stream SDK v2.0." This is on top of many bug fixes that include MW2, Wheelman, and various OpenGL titles.
