ATI has released ATI Catalyst 10.9 drivers (release notes) for Windows 7, Vista, XP and Linux. The drivers are also available via Steam. Catalyst 10.9 offers performance improvements for S.T.A.L.K.E.R.: Call of Pripyat and Chronicles of Riddick: Assault on Dark Athena for certain 4000 and 5000-series cards. There are also new or updated Catalyst profiles for Aliens vs. Predator, Battlefield: Bad Company 2, F1 2010, and Kane & Lynch 2. Catalyst 10.9 also brings official support for hardware acceleration in the Internet Explorer 9 beta (which is now available).

Update: This hotfix-driver solves the HDMI overscan-problem. It also contains a new HDMI audio-driver. If you have an AMD system, look also for the latest updated AHCI-driver that are available now.
