still same issues…with latest nvidia driver 399.24 i get crash to desktop at turn 10/Microsoft splash screen. roll back driver i can get a lil further into game but still crash to desktop. right before it stutters and hangs for a second sound and video. if i disable all sound outputs i can start game then rein-able to get cut scene audio only like most here, i have not noticed any difference in changing audio bit or quality.
