The game seems locked at 24 FPS (or some other low refresh rate) you can fix it by doing these:
- There are 2 possible solutions for that:
- You can try adding the -refreshrate 60 (replace 60 by the refresh rate you want) to the command line. This will force the game to request this specific refresh rate.
- Another workaround for this is to run the game in borderless fullscreen. To do this, you can simply launch the game with the -borderless command line or set the “UseBorderlessFullscreen” option to “True” in “%userprofile%\Documents\My Games\Outlast2\OLGame\Config\OLSystemSettings.ini”.
