On Windows copy Engine.ini to folder C:\Users\%USERNAME%\AppData\Local\Stalker2\Saved\Config\Windows and replace an existing file. Change your settings in game if you need to change them!
On Linux you can use ~/.local/share/Steam/steamapps/compatdata/1643320/pfx/drive_c/users/steamuser/AppData/Local/Stalker2/Saved/Config/Windows/
You can also copy settings from GameUserSettings.ini (but pls make backup of your file before, it contains games settings which you selected in the game: graphics quality, resolution, and other settings etc).
I enabled mostly High and Epic settings.
To get more FPS, change them.
Avg not less than 60 FPS in most scenes (but FSR is disabled, and ResolutionQuality=100). Very playable with very, very good graphics quality!
P.S. Let wait for improvements from devs
