I was having display driver crashes - mainly the game would freeze straight after coming out of the menu's/iventory, the screen would turn black and i would have to alt tab out - then in event viewer it said the display driver had crashed. This would always happen within about an hour of playing, sometimes within minutes.
Then, after some researching, i set the power mode in the nvidia control panel to "prefer maximum performance", then turned the games vsync and 60fps lock off (ie v sync off and fps to unlimited), set v sync on in the nvidia control panel and made the game fullscreen ( realised it was running in borderless window mode).
Since then, not a single crash in about 8 hours of play
I suspect the games fps lock does some funny things to the power modes on our cards and from switching to the menu to the game, the voltage doesn't keep up with the clock quick enough sometimes causing a crash.
