Hello I've been using the very latest Nvidia driver along with the provided HD audio driver. I have crashes to white screen loss of audio and ctl-alt-del gets me out.
Even if you aren't using HDMI I found it stall caused issues unless I actually disabled HDMI in the windows control panel.
I am now trying older HD audio drivers as well as complete drivers from Nvidia to see if the older drivers will work I'm guessing nvidia and ATI may have made some fundamental changes to the drivers that didn't exist when the game (never use this term on dcs forum :-D) was being developed. just guessing here. But if I come up with a driver that works I'll post here.
