100% GPU Utilisation with MPC-HC using CUVID

Question

I'm using MPC-HC 1.7.8 that came from a K-Lite pack using the LAV (0.64) splitters and so on. On windows 7 64bit, with a Nvidia GTX 770. I want to use madVR and CUVID for the best playback, however having CUVID selected in MPC -> Internal Filters -> Video decoder causes my GPU to use its maximum clock all the time which uses a tremendous amount of electricity (and heat and so on). When DXVA2 is used the load goes up and down during playback, it's more on 1080p videos that is, its using as much as it needs. Changing to EVR-CP makes no difference in either case.

How to configure all these tools so that I can use CUVID without causing it to take full control of the GPU constantly?

Answer 1

The NVIDIA driver does this automatically when using CUVID, CUDA, or OpenCL.

With a tool called NVIDIA Inspector you can force the GPU in a desired powerstate for specific applications (such as MPC-HC).
