You need to wipe attackontitanvr folder in your documents folder because you have enabled directx 12 in the save file and the drivers cause it to crash. Deleting the folder will revert it to default directx 11.
there are options to change the tree generation settings. Like generation radius , simplification radius etc . Look in the back pack menu options and pause menu

you didn't focus on the game first by clicking on it, turn on dlss , also if it runs terribly its your issue ,not the game's optimization issue. it's optimized , players with worse pc record it no problem at max fps.
