The system is rendering Windows Aero without the NVIDIA GPU being enabled. That means there must be another DirectX-capable integerated GPU in the system that is on when the NVIDIA GPU is disabled.
How does the system decide when to switch over to the second GPU?
- erik 17y agoOptiums 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....
