Add custom metal shaders as video filters (+ support for slang shaders) #4825
Description

Huhh. This would be fun indeed. Maybe I'll get there one day. Added as enhancement request. :)

[-]Add slang shaders as filters[/-][+]Add custom metal shaders as video filters (+ support for slang shaders)[/+]on Nov 12, 2025 I second this. I often play old games thru emulators and all have their own shaders to varying qualities. Check out OpenEmu, public code and they do a great job as they are macOS only. But having that effect globally is the dream. No one has even done anything like it and I’ve looked it. 😬

this would be ideal as RA ships with hundreds of shaders. But even basic support for GOEM would be a game changer

I'll admit this feature request is a long shot and has niche applications (and can be closed right away if deemed ridiculous or too difficult to implement).
I'd love to see slang shader support as possible video filters (https://shader-slang.org). Examples of them being used are in RetroArch (https://www.retroarch.com) (and to some degree OpenEmu), to simulate CRT, NTSC/PAL effects, to scale low resolution images to something higher definition using edge smoothing (Pixelate creates low resolution from high resolution, edge smoothing scalers create high resolution out of low resolution).
