Wait for Vsync suddenly locking my frame rate at 30 instead of 60.

This just started happening today. I always used the Vsync option because without it, even locking the frame rate at 60, it still can get kinda wonky at times. But today for some reason, with Vsync turned on, my frame rate was locked at 30, which seems a bit weird. I thought it was a simple "just get into another game" thing that has fixed past random issues I've had, where just queuing up and playing another game basically made the issue go away.

But this has been persistent, and I've been hopping into customs to see if I can make it go away. Just turning off Vsync isn't really a fix, because for some reason League loves to get jittery and stutter, especially when moving the camera.

If there's any way to get League to realize that Vsync should lock at 60 frames, that'd be dandy.
