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
