Realism upscaled changes the way Minecraft looks by replacing the textures with their real life counterparts. The textures are mostly self taken photos or if too hard to take also improved AI-generated pictures with only the most realistic ones being actually added as a textures. There are also some textures drawn on the computer like for example the ghast tear and all of the paintings are self drawn on paper. This took months to make and I hope it works well with vanilla minecraft.
Tipp: it works the best when used with realistic shaders
