   Execution time of Cg programs (GPU)
  Hi All,Does anyone know how to measure performance of executing Cg program on GPU?I don't want to get FPS but I want to get the execution time of Cg program on GPU.In Microsoft DirectX is some technique called "Queries" which return information when GPU is idle and force to execute all instruction hold by buffer on driver (to execute by GPU).My question is: is there (in OpenGL) similar technique to this in DirectX "queries" which return me when GPU is idle (after executed Cg program and other instruction)?Thanks,RK.
