I'd like to report back my findings:
I first tried on my old computer with an AMD card,
on AMD GPUs there's no feasible way to limit the fps to 60 unfortunately.
The good news however is that it does work on Nvidia.
Here's a guide to all Nvidia owners out there with speed issues on this game:
1: Open Nvidia Control Panel (Not GeForce Experience!)
2: Click on "Manage 3D settings"
3: Go to "Program settings"
4: Click "Add" and then click "Browse..." and go to where the game's .exe file is
5: Add the .exe file, it should now come up as "game.exe"
6: Under "Specify the settings for this program:", scroll down to "Max framerate"
7: Click on "Use global setting (off) and you'll get a new menu, click on and type in "60"
8: Click "Apply" and you should be good to go, open up the game and press "F2" to confirm that you have 60 FPS.
