    Apple and Windows Drivers, it just don't matches. AMD sells many more GPU's thanks to Apple, but when it comes to iMac driver support, it's seems that it's not that important for AMD. You've probably noticed by know that by default, you get the ATI 10.4 driver. Since Apple is using so called "custom" cards in certain iMacs ( example: the 5750 in the 2010 iMac is a 5850 Mobility Radeon ) it's not always easy to install the latest update.
    Follow these simple steps:

    1. Uninstall the current ATI bootcamp driver completely and reboot your iMac.
    2. Download and install the latest "notebook graphics" driver:
    http://support.amd.com/us/gpudownload/Pages/index.aspx

    ATTENTION: If you're upgrading from 11.x to 11.6, skip step 1!

    This small driver update from 10.4 to 11.6 will add the following improvements:
    - GPU acceleration of H.264 video content using Adobe Flash Player 10.1 ( or higher )
    - Video De-blocking support ( Reduces blocking artifacts seen in low-bit rate video during playback )
    - Mosquito noise reduction ( Reduces mosquito noise seen in highly compressed progressive video, during playback )
    - Official support for OpenGL 4.0 and OpenGL 3.3
    - Support for OpenGL 4.1
    - OpenGL ES 2.0 support
    - Enhanced Pull-down detection
    - ATI Radeon GPU acceleration of VLC 1.1.1 ( or higher ) Media Player
    - Video accleration for HD WMV video content
    - Enahnced Dynamic Contrast video controls
    - Enhanced Video Quality default options
    - Catalyst AI Texture Filtering updates
    - Tessellation Controls
    - Morphological Anti-Aliasing support
    - Stereo 3D gaming support
    - Performance increase in 3DMark11/Vantage and many games!
    - A lot more Catalyst™ Application Profiles
    - Many bugfixes/resolved stability issues and enhancements for Windows 7!
    - And a lote more I probably forgot to mention...

    I can't get this to work. I uninstalled my AMD driver via Device Manager then did a restart, but I still get the same "Your computer does not contain a proper graphics adapter" when I tried to run the AMD Catalyst installer from here. What am I doing wrong?

    Using a 2011 iMac 27" with AMD 6970M 2GB

    Can you run GPU-Z and take a look at the Device ID that is mentioned there?

    For example:
    [​IMG]

    My card is supported because it's included in the 11.6 inf:
    "ATI Mobility Radeon HD 5800 Series " = ati2mtag_Manhattan, PCI\VEN_1002&DEV_68A1

    Your GPU-Z should show "1002 6720". If it doesn't show that, let me know.

    Please post a screenshot of GPU-Z.

    Well, something is rong here, because you told me that you've removed the drivers, while GPU-Z is still showing 11.2. So you did not remove them correctly.

    No, I did remove them, then I put them back on when the AMD driver installer didn't work.

    Did you want a screen with the drivers removed?

    Just one. With bootcamp drivers it shows "AMD Radeon HD 6970M", when I unistalled them it shows "Generic VGA Adaptor" or something to that effect.
