How to fix crtsim mask scale?
I tried so much but I can’t fix that
Sorry for the “non-answer”, but crtsim doesn’t seem to scale its mask well at certain resolutions. You could try to fiddle with its mask scaling parameter, but it’s unlikely the results would be much pleasing. Why don’t you try another shader? If you need some suggestions, just post your machine’s specs and I’m sure people will advise something interesting for you.
If you just want a basic, nostalgic feel, then I suggest you trying newpixie-crt and tweaking it to your taste. Although not exactly accurate, it’s very easy to set a old-tv-style with it.
No visible scanlines gaps, some from bezel/koko-aio/Presets-4.1/tv* may fit as well.
Thank you very much for your suggestion, I will try that at soon.
