Once again, I can't really help but be careful with profile=gpu-hq since it also enables debanding.
To see which options are activated when using gpu-hq profile:
mpv.com --show-profile=gpu-hq
In my case, I have this:
Code:
scale=spline36
cscale=spline36
dscale=mitchell
dither-depth=auto
correct-downscaling=yes
linear-downscaling=yes
sigmoid-upscaling=yes
deband=yes
So if you really want to compare things, you'd better use these options individually.
