I have this problem after I recently setup my new drivers for nVidia GeForce Experience.
When I try to play in full screen, my second monitor (1280x1024)
turns black after some flicker, and the game on my main monitor
(1920x1080) goes with a "solid" 10-15 fps.
In windowed mode it's fine, capped at 120 fps manually.
I assume it tries to make full screen with both monitor in the same
time and the difference in resolution messes it up. Any idea how to
I already tried disabling my Nvidia Experience, but it still dowa the same...
