60hz playing at 50hz? Help

[emrekose5]

I have recently changed my motherboard and PC case. However an issue has popped up. My games locked with Vsync are all running at 50FPS instead of 60. My nvidia control panel says 60Hz, pc says 60hz, but all my games are 50fps.

My VBA emulator runs at 84% speed, and 84% of 60 is 50.4, so my games are all running at 50.4 FPS which makes no sense since all my software and settings say 60hz.

I need urgent help, I dont know what to do.

Okay, I fixed it by updating the drivers of my Monitor so the name changed from "Generic PnP Monitor" to "AOC 220W".
