The white paper on nvidia's site http://www.nvidia.com/object/optimus_technology.html says these three automatically power on the GPU: " DX Calls: Any 3D game engine or DirectX application will trigger these calls DXVA Calls: Video playback will trigger these calls (DXVA = DirectX Video Acceleration) CUDA Calls: CUDA applications will trigger these calls "
The lack of working profiles and API seems pretty problematic. One could always run some CUDA code at startup, but it doesn't say how shutdown is determined, and this really reeks of a kludge.
