    Quad Buffer SDK on 7970M with switchable GPU

    archy

      Stereo output is not working on my 7970M. Both 120Hz frame sequential using Display Port and HDMI 3D modes do not work. The switchable graphics is set to the amd card. I'm using a Samsung S27A950D.

       

      It fails when calling CreateOffscreenPlainSurface to create the FOURCC_AQBS command surface. It looks like the driver does not support this or the switchable graphics interferes somehow? To my understanding this call should succeed even when no 3d display is connected?

      HD3D enabled games that work on my desktop system do fail too.

       

      Should the Quad Buffer SDK work with the current drivers on laptops having switchable graphics?

       

      Thanks
