This article provides information on the latest posting of AMD’s software suite, AMD Catalyst 11.4. This particular software suite updates both the AMD display driver, and the AMD Catalyst Control Center. This unified driver has been updated to provide enhanced level of power, performance, and reliability.

Package Content
The AMD Catalyst software suite 11.4 contains the following:

• AMD display driver version 8.841
• AMD HydraVision for Windows XP, Windows Vista and Windows 7
• Southbridge / IXP Driver
• AMD Catalyst Control Center version 8.841

Important ! Caution !

• The AMD display driver and the AMD Catalyst Control Center can be downloaded independently of each other. However, for better stability and performance AMD recommends that both components be updated from the same AMD Catalyst release.
• The AMD Catalyst Control Center requires that the Microsoft .NET Framework SP1 be installed for Windows XP and Windows Vista. Without .NET SP1 installed, the AMD Catalyst Control Center will not launch properly and the user will see an error message.

Notes

• When installing the AMD Catalyst driver for Windows operating system, the user must be logged on as Administrator or have Administrator rights to complete the installation of the AMD Catalyst driver.
• These release notes provide information on the AMD display driver only. For information on the ATI Multimedia Center, HydraVision, HydraVision Basic Edition, Remote Wonder, or the Southbridge / IXP driver, please refer to their respective release notes found at http://support.amd.com/.
• 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
