Gave one of our newest builds a run today, just to give you a little perspective... My GTX1080ti utilization was at 40-45% with vSync turned on (vSync turned off isn't a good idea - my room became a sauna (among other things)), with everything in the game settings at maximum. FPS was a silky smooth 60 fps in 1920x1080 resolution. However, the CPU side of things... my AMD Threadripper 1950x absolutely ate whatever JWE threw at it for breakfast, and used no more than 10% CPU at any given time.
That should give you and other folks a decent benchmark on the game's upper end of things.
Meeeeh. Tell about the real deal !! UHD + maxed out settings = ? FPS. Does the 1080 ti hit the 60 fps or even more?
If it does...i just need to go shopping i think.
