Something that I did which worked for me is exit out of the Gforce experience. For most of us that loads automatically and we dont even think about it. I had the issue where dx 11 would crash with a note saying that the game stopped working. I then switched to dx 9 and it would just crash with no note. Rolled back drivers nothing. Reinstalled game nope. It wasnt until i exited the gForce experience that it would load under both dx 9 and dx 11.

Remember gforce experience interacts with your games and monitors and even optimizes your game. So you are going through 2 programs before you can even play the game.

Hope this helps.
