    Cannot use GPU acceleration with 64 bit CS5 under 64 bit Windows 7 with two cards ATI & nVidia

    GT-Force Level 1

      Subject sums up the problem, but here are the details:

       

      My ATI is a 5850, and I have drivers 10.6 installed. That's my primary card connected to my main monitor.

       

      The second card is an nVidia GTS 250 connected to my second monitor with 258.96 drivers.

       

      CS5 does not detect my GPU(s), hence, does not enable GPU acceleration. It says:

       

      "Graphics hardware acceleration is unavailable. You will need to upgrade your video driver and possibly your video card" both of which are obviously wrong, since I have the latest CS5 supporting drivers installed for two cards that can run GPGPU applications!

       

      Any suggestions?

       

      Thank you.
