I've never got MADVR to play nice with HDR movies full stop, totally hammers my i5 2400, I now play these using XPLAY through plex on my TV, scrapped the idea of getting HDR working for movies, too much of a faff having to turn on HDR first in windows, they really need sort that out properly so the HDR tag is switched on by the software and not a switch in windows.

Nvidia + madVR + LAV + MPC = UHD HDR BT2020 10bit Full Screen auto HDR mode on and off.

cheers but I find ATI cards more stable for HTPC use and MVC 3D works spot on every time, always have problems with NVIDIA 3D. While there isnt much HDR content i'll stick with my ATI card and just play what HDR stuff I have though my TV/PLEX.
