I stated a couple of times that the default presets are a bit “shy”, not aiming for a specific crt tv model and mostly suitable for a 1080p display. It’s so on purpose.
I guess the “kurozumi” preset could get a better tweak with the new iteration on the shader than the older guest-dr-venom, but the purpose is quite the same as the royale-kurozumi that’s to achieve a PVM crt look. But ofc. you can tweak further both if you like.
Tweaking afterglow:
- more persistence means longer trails
- if unsure persistence for different RGB values is best the same
- afterglow manifests itself on black pixels/areas (for authenticity)
And that’s not too hard i guess. Ofc afterglow looks better with some games which use black background etc.
