    Nvidia inspector measures VPU usage and GPU usage. What does VPU usage measure ? And how does VPU usage relate to GPU usage ?

    VPU=video processing unit

    vpu usage doesnt relate to gpu usage..
    vpu shows usage when playing videos..the higher the resolution the more usage, eg bluray has higher usage than HDTV, which has higher usage than DVD
    also stuff like wmv (and some other formats) is decoded on the vpu (depending on the app)
