So, I am using Windows store version (thanks to UltimatePas for 2$).
On my Threadripper 1950x and Strix Vega 56, I am getting 87 avg in 1080p. I did download ultra high-res textures before benching. Everything was on ultra.
Temp went to 82C on GPU and 68C on CPU.
The highest clock on GPU was 1490Mhz (which is low, as my card goes to 1700Mhz in other games), and 4009Mhz on CPU. Not all cores have been used. CPU was actually very little taxed.
So this game is mostly GPU bound, and will run great on even quad cores I think.
