Put the summary of the bug you're having here

What I expected to happen was...:
I expect the game to sync to my monitors refresh rate at full screen

What actually happened was...:
when in full screen mode the frames are limited to 60 fps. when in a windowed mode it runs at 165 fps like it should. 

Steps to Reproduce:
1. In the Nvidia control panel 165 hz is selected and g-sync can be set to full screen, or full screen and windowed and the program resets the monitor and sets the refresh rate to 60hz
