Please help me to get that crispy pixelated look in GZDoom

[Sergeek]

Version 4.14.0. I wand to play the PSX part of DOOM CE. I usually play with xBRZ, but this time, I want pixels. And I have no idea how to approach it.

At first, I tried to disable any texture filtering, then enabled NormalNx resize mode. But after some testing, there was absolutely no visual difference between NormalNx and no resize at all. Then I tried to put some Trilinear filtering on and this is where NormalNx started to shine - the resize mode kept that filtered smudgy mess pixelated, but only to some extent. Up close some pixels behaved weird, with smudged edges. And at a distance monster sprites became noticeably smudged, no filtering had way sharper results.

I'm a layman so this all is a mystery to me. What settings would you recommend for a sharp pixelated picture?

"None" is the only filter that will be truly sharp. Everything else will apply some level of filtering, either to the texture as a whole, or the mipmaps (textures downscaled at distance).


In my opinion there are only two other (combinations of) options worth bothering with:

Texture Filter: None (trilinear)
Ansiotropic filtering: 16x (max)
High quality resize: None
This will keep the textures unfiltered close up but smooth them out over distance with mipmapping. Good visuals up close, no nasty shimmering in the distance. Good performance. This one is my personal preference.


Texture Filter: Trilinear
Ansiotropic filtering: 16x (max)
High quality resize: NormalNx
HQ Resize multipler: 6x <<<< IMPORTANT
Without the last setting, NormalNx does nothing. This setting will upscale all textures with no filtering, then apply the texture filter. This means you get almost completely sharp textures up close, but they smooth out much more nicely over distance, also avoiding pixel shimmering. However as the warning indicates, this uses up a lot more VRAM and may not be appropriate for all systems. Can be softer than the mipmapping option.

Thanks for elaborate response! I think I'll stick with no filtration.
