Sorry for 'bumping' this thread but after three months I thought I could ask again because yesterday evening I compared render times watching the Italian "SUSPIRIA"-BD.
D3d11 native: ~ 28.8 msec
DXVA2 copyback: ~ 23.8 msec
I think that is a huge difference and I really could use these 5 msec to further increase performance in MadVR !! I am of course aware that I could always change this every time
depending on the content but I think software should do these tasks for users.
I understand that a profile system might be way too much work but it would be great to have a basic setting so that LAV chooses automatically the decoder !!
Something like:
SD = DXVA2 copyback
HD = DXVA2 copyback
4K = D3D11 native
You could make also it optional so that users with enough GPU horsepower don't even have to bother. Best wishes
