The game seems to have a bug where if you have freesync enabled it has issues with brightness flickering on screen. I at first thought it was my pc but I had a friend try it and he gets the exact same issue. My specs:
i7-6700k 4.5ghz (Overclocked)
AMD Vega 64 x2 (Crossfire)
32gb of DDR4 3200 Ram
If anyone knows a fix that would be awesome, or just others with the issue so I know its not just me. Thanks.
