What are they doing? FPS Shalit (Metro Exodus)

Gifts guys. In short, I decided to go Matroska all cases download pirates(I'm just poor), and start to start put everything on low, reduce even the screen resolution off all garbage, etc. And in the end I get: FPS walking as soon as you can. I of course quickly in the Internet, watch what's up, I started to watch all the configs, then optimization on this website. I changed the settings in the NVIDIA control panel, still spinning graphics in nvidiaProfileInspector, then shaman in the user file: turned off the shadows of the grass, removed and HDR blur off, antialiasing on attribute read Only what do you think? That's right, nishisaki has changed the way FPS were walking and walking. Don't know what to do now. Help to solve this confusion.
