1 core is pretty much totally loaded with and without copyback.

Using my Power Plan (CPU@1.53 - 1.56 GHz), UHD SDR 10bit 59p sample + NGU Sharp Low chroma + SSim d1 100 to 1080p:
2160p_59fps_hevc-LG_2_DEMO_4K_L_N_06_Slam Dunk.mkv
d3d11 native (madVR / mpcbeVR):
CPU MPC-BE: ~1.8 % / ~1.8 %
d3d11 copyback - no zoom control/black bar detection (madVR / mpcbeVR)
CPU MPC-BE: ~5.8 % / ~3.8%
d3d11 copyback + zoom control and black bar detection (only madVR)
CPU MPC-BE: ~9.2 %
Load is equally distributed between threads (3-4 threads having load <20% out of 12).
Edit:
I added mpc-be video renderer as well. The diff between madvr and mpcbeVR is 2% using d3d11 copyback, while there's no difference using d3d11 native.
