I have never exited the game yet, because always crash before that,
Sometimes right in the initial menu, sometimes when entering a server, and most of times while playing (5~30min).
The game freeze and you have to alt+tab to close then, a message is already in desktop saying that the Arma 3 is not responding.
While you are playing the crash always come this way
The game freeze for a sec, the sound stops, the game back for a fraction of sec with the sound,then the game stop working
