For the past several months, I have crashed to desktop several times per night. For the past week, it has been several times per hour to the point where I was getting exceptionally frustrated and starting to HATE the game.
I have a high-end system with a single GTX 980 TI, I7-4790, run the game on a SSD...really good stuff. Oh yeah, and I run the game on my 4k television.
All my drivers were updated for both windows and Nvidia.
The crashes seemed to take place occasionally during a very graphically intense situation. I run the game on max settings.
I ran the game on FULLSCREEN mode. I tried switching to WINDOWED FULLSCREEN and voila! the crashes stopped. Occasionally there is some lag stutters but otherwise, I have not crashed to desktop since switching to windowed fullscreen.
I'm not sure why it does this...perhaps the fullscreen mode is more graphically intense on the graphics card? I'm not a computer guru, so I couldn't figure it out; but I'm not going to look a gift horse in the mouth.
I hope this works for others.
Happy gaming!
