I was expecting the graphics to be a lot better. On Ultra settings, it doesn't even look as good as Doom 2016 to me. Does the Nightmare setting look significantly better?
I'm on nightmare (not "ultra nightmare") and it looks just okay. It was designed to run at 60fps on super old consoles, and the TAA plus sharpening is pretty aggressive, making it look a little flat and processed. It's really the design that makes it look good, everything else is pretty meh. Also I think motion blur and chromatic aberration hide a lot of how flat it looks normally, so with them off it looks even meh-er.
