Thank you, many of which we dwell, perhaps, even some direct experience of any holder GTX 980 / madVR would like, I see you are using Cuvid as video codec instead of DXVA2 Copy for its GTX 970, it is as good as choice Cuvid primarily of DXVA2 Copy?

In my experience with NVidia card, I found DXVA2 copy-back is better than CUDA . Sometimes using CUDA leads to freeze / crash especially when using with SVP.
