Since DXVA2 scaling seems to equal some kind of bicubic on Nvidia, it's actually not too bad afterall and dimensions better than bilinear.
There don't seem to be any other quality drawbacks with recent madVR version on Windows 10 Creators Update, no banding problems.

New DX11 decoding API btw. isn't called DXVA anymore, afaik, but D3D11VA.
doing a short test:

dxva: https://abload.de/img/dxvaoeob0.png
bilinear: https://abload.de/img/bilineary8of4.png
bicubic: https://abload.de/img/bicubicz8qci.png
they are all the same frame the shift comes from the scaler.
it is as bad as ever and bilinear is doing better.
