So far I have been running the game with my headset just fine. The only other thing I can think of is that I did a file verify and everything checked out. Not sure what changed other then the day.

Hi snipe,
thank you for your feedback and keeping us updated! Appreciated.
We are currently looking into this.

I left the game on the server screen for a few mins and it crashes the exact same as logging into a server.

Tried disabling AVG, still crashes the same. Added files from LOCAL\DayZ folder

I may have solved this crash issue. I have a Steel Series Siberia V2 USB headset, and I have all audio running through it. I had set it to speakers the other day disabling the headset and I ran the game tonight and it worked flawlessly for over an hour. I will do more testing to make sure

I was able to play for 2 hours tonight with no issues and I was using the headset so maybe it was not the issue. Will keep monitoring.

I have been playing without any issues still, so my issue seems to be resolved but from what I read it is still an issue with others. Not sure how it was fix but I am glad it is. Will keep updating

I've had the same problem. Dual monitor setup, single GPU (7970), stock clocks, latest drivers. It seemed to happen when I approached loot and used the TAB key to bring up my inventory view. It took me a while to notice a pattern but when I finally did and remapped to a mouse button the problem seemed to stop.

The game would CTD but still be running, my mouse would act janky and the Dayz icon in the taskbar would flicker. After a few seconds I could regain control of my mouse and either click or ALT+TAB back into the game.

The issue only occurred in .51 experimental.

I too have dual monitors, but I was never able to regain control of the game, it would always be running still but I would have not visual of it just desktop. Your issue sounds similar but the fact you could continue playing makes me think it might be a different one as I was having the game crash on the main screen or server screen just the same as being in a server. It seemed to happen withing a few mins like the GPU stopped responding and recovered but no message would show.

Well for what ever reason I have had many many hours of play since this issue and it has not come back (yet). I would say close this ticket for now.
