Using AI to upscale game textures, how?

[Wasmachineman_NL]

Title. As some people might know, I have a real hard-on for the Vulcar Ingot in GTA V, but it's GTA IV era textures are starting to put me off.

So, is there a way I can somehow upscale them? I was reading about ESRGAN and Gigapixel AI but I know jack about AI/ML besides that.
