game crashed.

I have completed game and was in brothel, then came out and started back tracking, was only playing for about 2 minutes the game screen went black but could here me still doing things in the background but could not see any thing then game crashed and shutdown, back to desktop.

I also noted that when you get to the larger one eye monsters that some of the pods when shot just disapear no sound and have a slight delay.
I will say the game ran pretty well overall.

Running game on full spec.
