VD2 Decoder here: avlib-1.vdplugin from 15.03.2020.
If I hide iGPU (Intel UHD750) and make the discrete nVidia GPU (RTX3080) available, dGPU will be preferred + a little bit CPU (i9-11900K)
Here playback of AVC 8bit/HEVC 10bit FHD use 30% of a RTX3080, CPU is at 6%, all 8c/16th do something.
If I make the integrated GPU (Intel UHD750) available, VD2 decoder will use all 8c/16th CPU cores plus iGPU as needed (17% i9-11900K CPU + 6% Intel UHD750) and nVidia RTX3080 sits idle.
