I have been having the same issue as many other people.
The game will freeze. Sound will continue, however screen freezes. Can see the last image I saw on screen before freeze. Only thing I can do is force close it. Drivers are updated, OS is up to date, have attempted closing just about everything aside from whats needed when playing. I have disabled steam overlay, GForce overlay. I am unsure what else to try at this point.
CPU - 1070k
GPU - 980ti
32g Ram @ 3600
Any help or suggestions is appreciated.
