I've downloaded the latest App SDK (version 2.7) and installed it on Windows 7. I built and executed a couple of example apps like BoxFilter and NBody in Visual Studio 2010. The problem is that those example apps don't see my NVIDIA GeForce GTX 460, even though it's OpenCL compliant, and it just defaults to the CPUs. Here's the output of BoxFilter. Am I missing a setting somewhere (like extra VS2010 project settings)? If you need more info, please let me know.
Thanks,
