But on separate linesscale=ewa_lanczos scale-radius=2.0
Yea I figured that out.
To narrow things down, I now have just been working with mpv itself the standalone player to see if the conf file is actually doing anything and direct playing the media file via mpv.exe just to mess wiht things and learn how to tweak it.
I see no sharpening happening at all even set to the max value 16.0.
However, it is processing or doing something, as, when i set a high value, when i go full screen with the vid, it freezes for a bit then is very laggy when it plays.
Setting lower value, no freezing when go full screen.
