3080 - most settings maxed, except for shadow settings at low (RTX shadows are just for sunlit objects), and volumetric fog one level from highest. All RTX settings on, RTX lighting at Ultimate, DLSS on "Balanced". Smooth frames in 4k.
This is the one game I wouldn't mind having a 3090 for, but I was lucky enough to land the 3080 as-is.
Edit - Ha, I was on the earlier page 1 set of posts when I posted this thinking that was all the posts. Oh well, there you go.
