This is VERY interesting in how drastic things change, but how little things did change according to NVIDIA. And I think the original poster should definitely update his post to make this clear: DLSS 5 is NOT touching the original models, polygons, textures or materials in ANY way. I already see a lot of people claiming they changed Grace's face (and others) with AI slop. And I get that, but that is not what is happening here. Just slapping on AI slop assets over the top would definitely be wrong.
DLSS 5 ONLY changes the the way lighting is hitting those original models/polygons/textures/materials. That's it. JUST the lighting.
And yeah - WOW, is there a massive change is how things look because of that.
I'm not entirely sure how I feel about it yet, but again, in the Grace example - THAT is her ORIGINAL face. Her lips, eyes, etc. - all that changed is how the lighting is reacting to those things. It really is crazy how different it looks.
