This mod replaces vanilla sprites with higher resolution versions created with machine learning, making sprites look just a bit better.
Does it impact performance?
As long as you have enough VRAM there shouldn't be any performance impact, the base game consumes about 1.6GB of VRAM on the highest settings.
Vram consumption of each mod:
Base: ~500MB
Logistics: ~600MB
Military: ~200MB
Production: ~250MB
Terrain: ~250MB
With all mods enabled you should be using about 3.4GB of VRAM, if your graphics card doesn't have enough VRAM you can pick and choose which parts of the modpack to use.
I want to thank Zangeti for creating his mod TextureBase which allowed me to put this thing together.
