i'm testing my zen 2 right now finally some bad results.

i get 15 % CPU load on an 3700X something very odd is happening here.

1060 3700X 3200 mhz ram.
UHD 60p NGU AA mid chroma SSim d1 100 to 1080p

d3d11 copyback
CPU 15 %, GPU 19 MS
d3d11 native
CPU 11 %, GPU 14 MS
DXVA copyback
CPU 12 %, GPU 19 MS

1 core is pretty much totally loaded with and without copyback. if an 8 core CPU is loaded like this my 2 core intel shouldn't be able to do this idling...

edit: the CPU load seems to be a part of madVR...
can you guys please retest with mpcVR just for the CPU load: https://github.com/Aleksoid1978/VideoRenderer/releases
all you need to do is install and load it as an external filter.
