Strange screen and sound issue.
While I'm playing the game with shadows on low or high, no other settings make any difference, my screen will go a blank color, sometimes grey, black, brown, red, doesn't really matter. I'll then see the loading screen for a second and the game will come back on, but my sound output changes usually to my monitors output which is connected with HDMI. If I'm using my monitors speakers, another duplicate will be created in my sound options and will switch to that which I can then switch to in order to have sound output. The game will continue to go blank in random situations. It continues to do this. If I turn shadows off, it doesn't do it anymore. I don't have any issues with any other games. I've tried using a DVI cable instead of HDMI. I've updated my graphics drivers. It was doing it before the expansion and does it after. My brother's game does the same thing. He has a GTX970 as well as me, but no other hardware is the same.

Oh, I've also monitored my video card health status. Temperatures don't surpass 50c.
