But nobody is talking about the environments and textures. I think they look incredible.

I have to disagree. In many examples, the lighting completely changes and colours are exaggerated. This completely changes the atmosphere of a given area.

Leaving aside the question of artistic intent, does this not lead to every player having a different experience? Or maybe even every session? DLSS 5 seems to fill in a looot of details and even changing things. How are they making sure it’s the same for every player?
