i have the same issue with my system i have a fresh install of windows 10 with just games installed and some software for my pc i have a i7 8700k 4.5Ghz and a 3060 ti and 32gb of ram and using a ssd i was able to play ultra maxed out 1440p no issues in season 3 and below but now season 4 came out high settings i get 40-50-60 fps and low settings i get 60 if i am lucky because my cpu is getting torched by this game 100% all the time and my gpu is at 50-60%
I get this same issue, I've tried turning off every application except 2042, it seems to get progressively worse over time. It will only be a second of input lag, then over the course of 10-20 min, it will just be 5 seconds of input lag no matter which key I press.CPU is 100%, fans spinning so hard my pc is about to take flight. My friend's pc has worse specs than mine but doesn't get this issue though surprisingly.
