Works well on my aging i7 4790k cpu and 2080Ti. 70-130fps on highest settings 3440x1440.
RE the lowering detail to give you an edge over opposition, this has been done with most online games since multiplayer was a thing.
I remember turning off things like foliage in soldier of fortune to make it easier to see enemies
Im fairly new to multiplayer FPS so this the idea of removing visual aspects of the game in order to remain competitive seems foreign to me.
I used to play PUBG with settings maxed out and would routinely get killed whilst hiding in foliage that (to me) looked like it was doing a marvellous job of concealing me ... it makes sense now.
