Comment (by markk):

 When using the nvidia proprietary driver, xrandr will not give you the
 actual refresh rate.

 The most reliable way I've found to check what is actually happening is to
 use glxgears (ensuring first that you have opengl sync to vblank enabled
 in nvidia settings) and ensure it shows roughly 50 or 60fps (or at least
 something reasonable).

 Then use nvidia settings to switch the rate to something else, exit nvidia
 settings and try glxgears again.

 If the actual rate isn't changing, then go back into nvidia settings and
 ensure 'Force Full GPU scaling' is NOT enabled.

 I'm betting that it is and once you've turned it off, all we be good
 again.
