OK, I didn't really get what you meant. My bet is that the system calls DXVA Checker use to get the device capabilities are independent of the Optimus setting in NVIDIA Control Panel.
D3D11 video decode probably doesn't respect that Optimus setting either, that's why I was suggesting to use copy-back if you want to use the Intel D3D11 decode. I understand if you'd prefer native mode, but does it work with copy-back?

Also, QuickSync decoding is a private Intel API and not a DirectX one so I guess it's not impacted by the Optimus setting in NVIDIA control panel either.
