Since contacting customer support is apparently entirely useless (just gave me an automated response telling me to come here), I'll explain my situation.
In advanced: My graphics card is an NVIDIA geforce gtx 860m, which is seemingly where the issue lies (All the forum posts that I've found with any issues I've encountered say that the op has a NVIDIA card Apparently AMD cards also are having issues)
To begin with when the game was in full-screen kept flickering, so I changed it to windowed borderless. That didn't fill up my full screen (only the top quarter of it), so after looking around about I found editing the .ini for the resolution increased it to the full size of the screen.
However then the game would crash (no error message) and my system would give me the message "display driver stopped responding and has recovered". After searching around some more I saw some people saying that the NVIDIA streaming service was likely the culprit, so I nuked it. Now it stops responding and crashes immediately on startup, where as before I could play anywhere between 2 and 4 minutes before it would crash.
Any help from here?
