Alternative models?

[YellowOnion]

Hey, so I think the weapon textures look great, but the world textures can look a bit weird in some situations.

As mentioned in another issue, some textures are rather noisy, and I wonder if some of the dedither models could help here, the 4xFSDedither variants look pretty good, https://upscale.wiki/wiki/Model_Database#Dithering

There's also the HDCube scaler looks promising.

I'm on AMD and Linux so I'm not really sure how to extract textures from Q2 or run pytorch on my hardware, I would love to do some comparisons otherwise.
