If everything is sped up for you, turn off V-sync!

[Biff Skeeto]

As the title says, leaving V-sync enabled will cause the game to speed up if you have a 144hz monitor, as it's created with 60 fps in mind. While a lot of people will understand this, I figured I might as well put this out there in case anyone doesn't know how to fix the problem!

Thank you, this fixed my issue as well.
