Before this update, i had no problem.
Now my game crash when i am playing Arma 3 (Westeland) after 5/10/15 minutes. All time.

Screen block, no error message, computer block.
Sometimes i can kill the arma3 process and my computer is ok, sometimes i must reboot.

Me and my friend has this problem exactly at the same time on the same server.
