S.T.A.L.K.E.R. 2 perfomance error.

[fukerzzz]

Hello everyone. Plz help me. I start to play a game. Everything was good, it was about 70 fps, until I died and loaded the save file. After I loaded it, I got 3 frames and about 2 sec input lag forever. I wait about 10 minutes, and nothing changed. I think, maybe game broke my save file, so I restarted it  and start it again. And the situation is the same. Everything was good until save file is loaded. 
I thought ok, maybe I need some mods. I found S2optimizedTweaksBOOST v1.01. Game start load my safe file correctly, everything was great exept... The crosshair. Crosshair on every gun of the game was broken. There is no crosshair any more - there is just some textures on it. 

Then, I thought. Ok. Maybe I need actual version of the mod? I downloaded it, the crosshair is fine now, but... The perfomance is broken.

 

So, Dear Readers. I need your help. How to fix perfomance of this game? I got rtx4060, r5 5600, 32 ram.
