If CPU usage comes mainly from displaying video in TRVCamView, try assigning vCam.FrameScaleQuality = rvmfscLow (requires RVMedia 9+)

With the above parameters, the CPU usage is still very high. The decoding does not use hardware decoding. It should be that FMPEG does not open hardware decoding. Can you open FMPEG hardware decompression?

By default, RVMedia uses codecs auto-chosen by FFmpeg. Usually these are software codecs that do not require special hardware and thus can work on any computer.
You can assign the specific codec name to TRVCamera.FFmpegProperties.DecodeVideoCodecName. But you need to know that this codec can decode your video format and it is compatible with your hardware.
