Adding 240p or 480p scanlines to upscaled 3d games

RetroArch Additions Shaders

Hi guys,

I’ve created my own preset of CRT-Royale that I really like, and it works great for 2d games.

I really like to upscale 3d graphics via core options to 4k as I have a 4k TV and really like the modern remastered look it gives to 3d games.

By doing so scanlines become invisible, after increasing the triad size to be compatible with the higher resolution I was looking for settings to increase scanline size as well but couldn’t do so.

I found a shader called res-independant-scanlines which allows me to insert 240p scanlines and it looks great for the PSX, however it looks like the max size is 288p, so that wouldn’t be good for 480p consoles.

I’ve tried Megabezel which I absolutely love and has this option, however upscaled to 4k it crashes, and I don’t like to downsampled look.

2 questions:

  1. Is there settings within CRT-Royale to insert fake scanlines of 240p and 480p size on a 4k screen?
  2. Is there another shader (or another method) I can append to my preset that allows me to introduce 480p scanlines?

  1. no
  2. yes, in the shaders, look in downsample/drez. there are 240p and 480p variants that you can prepend to force the res you want.

You can just open the res-independent scanlines shader file (.slang) with a texteditor and increase the limit beyond 288p.
