Try reducing settings in the game, there is a lot of 'fluff' that's turned on by default that stresses some video cards.
If that doesn't work, try uninstalling the old vid drivers, and install the latest version.
I keep my setting low already as that stops A LOT of game crashes for me
and my drivers are kept up top date
my video card is a GTX 970 if that helps as well
Which OS are you using? Win 7, 8, 8.1, 10?
You may need to either update or roll back your video driver(s).
If you are using Win 10, there have been reports that when 10 does an update, it is replacing manufacturer video drivers with MS WHQL video drivers. This may be causing the problem(s).
