That file is probably HDR, which means extra work needs to be done in the renderer (HDR tonemapping) if your system does not support HDR passthough (which it probably doesn't).

VLC has pretty much same decoder as MPC-BE and LAV. So that is not the issue. VLC does not do HDR tonemapping afaik, so that is why it performs better. Colors will look dull as well...

In MPC-BE do this:
1) Disable 10-bit/16-bit output in its video decoder settings. This saves bandwidth when copying data to GPU.
2) Install MPC Video Renderer and disable HDR conversion in its settings. I don't think EVR-CP in MPE-BE has an option to disable HDR tonemapping.
It worked! Even with madVR selected. No more stuttering. There's just one issue left: subtitles are gone if you enable MPC Video Renderer. Once you block and use any other decoder they will be displayed again.

Do I have to add another external filter?
