Help pls, I think I already made almost everything to solve it, but didn't find the solution yet!

In every game I play, except really low hardware demanding games this always happens, and it happens in a periodic way, a bunch of minutes in this state and it returns to normal performance after a couple of other minutes, the game in screenshot is called Atomic Heart and I'm pretty sure with that config, I can run this game very smoothly. Obs: general graphic settings in "medium". Thanks in advance!
