How to Unlock FPS
Follow these simple steps to Unlock The FPS Cap.
Go to:
C:\Users\[username]\AppData\Local\Darksiders3\Saved
Open the file called “GameUserSettings.ini”
Look for the line that says;
FrameRateLimit=0
Change it to what ever FPS you want;
FrameRateLimit=144.000000. If you want it totally uncapped, just set it to “FrameRateLimit=999”.
Do note if you go into the FPS setting screen in the game at anytime it will be changed back to 60 FPS and you have to edit the config file again.
