Issue title: [FlatOut] Can not select refresh rate above 60 Hz
 Issue body: I used to run Flatout at 100Hz, but after todays update I only get the 3 choices:

 - default
 - 59
 - 60

Can this be related to WidescreenFixesPack ?

I have Windows 8.1 Pro, GTX 1050Ti, resolution 2560x1440x32

 Comment 0: Turns out it was the (new) monitor cable.
While the desktop worked in 144Hz, Flatout Setup only offered 59 and 60.
After switching back to my old cable, Flatout also offers higher refresh rates.
