OK, I played the first three levels (edit: two, I guess the first doesn't really matter as it's an intro) with Steam friends. All max settings aside from that "extra raytracing" option or whatever it is - so 4K, ultra, and I am getting between 57-59 fps and the HDR looks amazing. With that option enabled I get 50-52 fps.
So if anyone is getting poor performance with a RTX 3080, might wanna look into if you have other processes eating up compute or something.
Oh and the Windows support for the DualSense is commendable. Feels the same as when playing on the PS5 as far as I can tell
Edit: ugh I got a Gingerbread crash twice in a row while joining an online session. Good news is the game is super active now, finding sessions instantly. Just hope you don't crash
