I'm running Bootcamp on a 27 inch iMac. My specs are i5 9600, 40gb ram, and a RX 580 GPU.
I was getting pretty consistent 60-70fps on Financial. about 2440p resolution, Medium graphics. When I would take damage and recover, there was a second little "screen" which looked like a damage layer mirroring the full screen. Dont really know how to describe it.
Couple stutters early on but they went away after I drove around the district.
The escape menu text was jittering around/flashing which was very odd, after I made graphics modifications.
Finally, when I was running around I was getting weird lighting artifacts, just like looked kind of like spotlights moving around my character.
