Re: Sims 4 is locked at 60 fps
@WoohooJuiceSim Please uninstall Razer's Game Manager Service. If that doesn't help, remove any other Razer apps you have.
If that doesn't help either, as a test, please remove your graphics card and plug the monitor into the motherboard so it uses the iGPU. While performance will drop off significantly, you should still see above 60 fps in some contexts; if not, drop down the settings and try again. The idea here is to see whether this fps limit is tied to the Nvidia GPU or is a more global system issue.
