I have a V7800 and when I install the driver and SDK, the only platform that I can find is the CPU platform (NO GPU). I have tried to delete all traces to previous installations of the driver and SDK (also using Driver Sweeper) with same results. Is the 7800 spported by the most recent driver and APP? Has anyone else had this problem? I would assume that the OpenCL.dll file is installed correctly, as I can see the CPU platform. I would think the problem would then be a driver type of issue.
