AMD has released new Catalyst 11.3 drivers for Windows XP, Vista, and 7.

The AMD Catalyst software suite 11.3 contains the following:

AMD display driver version 8.831
HydraVision™ for Windows® XP, Windows Vista® and Windows 7
Southbridge/IXP Driver
AMD Catalyst™ Control Center version 8.831

ATI Eyefinity™ technology gives gamers access to high display resolutions. As pixel count grows, the graphics horsepower required to drive the displays at a reasonable frame rate can increase dramatically. Depending on the game and system configuration, users may notice texture corruption and reduced frame rates when running games in multi-monitor Eyefinity modes.
Windows Driver Model (WDM) drivers are no longer bundled in the AMD Catalyst software suite. The WDM drivers install bundle can be downloaded independently through the AMD website
The Drag and Drop Transcoding feature is a beta level feature provided only for evaluation purposes. The Drag and Drop Transcoding feature is only supported on single and dual core CPUs, and supported on devices that support Media Transfer Protocol (MTP).
