Optiums is built for Intel's new Core i cpu's, where the cpu has a moderately capable gpu integrated on the same die. What I've read indicates that Nvidia is using a database of application profiles to determine if the dedicated gpu should be activated. edit: I just read that the drivers will use heuristics so that application profiles won't be needed in most cases. Basically, if an application initializes DirectX, CUDA or OpenGL, the dedicated gpu will be activated by the drivers. http://blogs.nvidia.com/ntersect/2010/02/world-meet-optimus.html http://blogs.nvidia.com/ntersect/2010/02/world-meet-optimus....
