Important for INTEL iGPU users.
Since ever, enabling dx11 option in lavfilters decoder was causing slowdown in video decoding, much much worse performance was noticable than dxva native, especially with highest resolutions. It was a few versions of Win10 and intel drivers back.

Now, dont know why, but enabling dx11 automatic, makes possible normal playing even with 8k videos. It does not drop any frame with nightly 2.1 MPC video decoder. It drops some frames with Madvr but its not so noticable. Madvr consumes much shared memory (intel igpu video ram) and it is almost filled at 8k (i see it in process manager). And finally, video playback crawls with EVR Custom presenter. This renderer does not convert HDR>>SDR tones, so it's the least featured among possible renderers now. Need to switch to another renderer finally on daily basis.

Take note, enabling dxva2 CB makes video slow. It must be some dx11 compatibility chain between decoder and renderer making dx11 playback better performance.

I didnt watch CPU usage, Not so important right now for me.
