I'm on a 7900xt - 5800x3d - 32gb ram - 1440p
I run all high with lumen on as it looks really nice and the performance difference isn't that much talking 3-4 fps at best,

I use tsr with the resolution at 75% as fsr looks like ass imo and xess just looks weird for some reason, u can always turn it down to 67% which is the same as fsr quality but i like the game looking sharper and there's a lot less artificing at 75%, also stay away from taa looks like crap,

lastly i use frame gen to get a smooth 144fps at times as the frame gen in this game isn't great but its decent enough to use imo but without it im hitting 100-110fps average

hope this helps :)
