Theres also a second option i like to use.

Open Window Settings
Click 'System'
Select 'Graphic Settings' at the bottom
After that, click the 'Search' Button, find oncehuman.exe (usually C:\SteamLibrary\steamapps\common)
Then click on 'Options' and 'High performance'

half oh the video is about windows configs and not og the game configs, I like that so we can use in other games too. Ty.
