But Intel GPU is slow for madVR
If you select the NVIDIA GPU for MPC-HC and then choose DXVA2 Copy-Back or D3D11 and select the HD 4600 in LAV, what happens? madVR still uses the Intel for rendering?

Read my first post.
D3D11 should theoretically work (see image DXVA Checker).

No. NVIDIA GPU active.

It works for me (see my signature), but I switched back to dxva2-cb, because there's no black-bar-cropping implemented with it in madvr yet.

With Optimus only one GPU is active from the perspective of the application. So if you select the NVIDIA GPU, then you can't use any functionality from the Intel one and vice versa.

No. Intel Quick Sync active.

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.

Depends!
DXVA Checker image №2 (if in the nVidia control panel selected Intel GPU).

Subtitles won't show up.

Using LAVFilters-0.70.2 and nightly build LAVFilters-0.70.2-88 with PotPlayer 1.7.7150.
When playing BD (mpls) or mkv's no subtitles show up.
Also using madVR v0.92.10
Perhaps this is a PotPlayer issue?
If not are there some settings in LAVFilters I'm missing?

With this setting I can view subtitles both embedded BD (PGS) and .srt, I can also load .sup and .srt.

With this setting there is no way to view or add any subtitles.
