I'm not using this game as a benchmark of anything, but at the same time, next gen consoles wouldnt be able to run this game at 4k/120fps, nevermind an actual next gen game lol.
Do you know how much power it would take to run a AAA game at 4k/120fps?, even SLI 2080ti's would struggle to do that in an amazingly optimized game.
The only game i could potentially see trying to do 4k/120fps (outside of experimental Inide game, or tech demo, like i said), would be a next gen Gran Turismo, i could see them trying it, but outside of them its a big NO lol.
