Sweet rig, man.
Since you're now with a 4K monitor, and you have CP2077 installed, I reckon that's one game to push your rig to its limit especially with the Psycho settings.
I'd also highly recommend
Metro Exodus: Enhanced Edition. That's probably the game with the most effective use of ray tracing I've seen so far (from YouTube reviews that is). In the same vein,
STALKER 2 should come out later this year.
Atomic Heart just released. However, it's developed by a Russian studio and apparently there are some pro-Russia imagery in the game...
Scorn, while not a full-blown shooter, does have some great visuals.
The
System Shock remake should come out next month. There's a demo if you haven't tried it yet.
Finally, I see that you have some of the Arkane games but no
Prey (2017) installed. Get to it ASAP!
