Fair comment. HDR implementation seems ok, not great. Certainly nowhere near GOW or Death Stranding (these PS4 HDR implementations were superb).Don't know about HDR, apparently it's not a great HDR implementation on console so I don't know how it is on PC.
I have a feeling that the desert is making everyone think the game performs better than it actually does. Go start a corpo path for 15 minutes and you'll see how the FPS tanks in the city (where you'll be spending most of your time) and how DLSS messes up the edges.
