/vr/ - Retro Games

So /vr/, can we have a filters/shaders thread?

I've heard some folks in here talk about how linear filters is the devils work. Is that really true?
I mean, my experience would be terrible with something like nearest neighbor filtering.

I user RetroArch with the build in Linear filter, and a 3 pass NTSCS S-Video shader mostly (pic related).
I this all right, from the standpoint of wanting to have an experience that's close to the original, without too many eye straining artifacts?
Help me /vr/, share you knowledge.
