Yes, (since we can't separate acceleration process from 2 cores, and my default player is assigned to nvidia), I just double checked it with few 2160p samples (on 1080p display) (I use the nvidia gpu in an underclocked state (470/800 vs 745/2000 (default))):
1. in underclocked state:
- DXVA Copyback direct can accelerate only: 24fps 33Mbitps, 25fps 16Mbitps
- CUVID can accelerate : 30fps 16Mbitps, 24fps 130Mbitps (!)
2. in default state:
- DXVA Copyback direct can accelerate only: 24fps 33Mbitps, 25fps 16Mbitps, 30fps 16Mbitps
- CUVID can accelerate : 24fps 130Mbitps (!)

(Bitrates are average bitrates according to mediainfo, bit it could get really high so that's when copyback fails.)
I understand that this is an extreme case, just wanted you to know how CUVID vs copyback behaves on my system.

Sometimes I get this, I think (it didn't happen for a month or so) a reboot solves the problem for me. Thanks for the explanation!
