The game loads fine and plays fine for about 30 minutes to an hour and sometimes less then that. Sometimes it does it after 10 minutes of playing. The problem i have is the game locks up after getting black, grey screens and the sound still works and some times i can continue to play and most of the time i cannot. The game will lock up my pc and i cannot even ctrl+alt+delete i have to completely restart my pc. This is the ONLY game this crap does this.

I am on windows 10 and i have a GTX 970.

Any help to fix this issue would be awesome!
