The game consistently but randomly crashes to desktop anywhere from 20 minutes of play to 2 hours. Some people are reporting quicker crash ranges than that, but I do find that I can sometimes play for up to 2 hours, but rarely any longer than that.
I'm typically playing in the king of the hill servers, but I have also had it happen on wasteland, breaking point, and battle royale. It seems to be multiplayer games in general. I do not play single player, as I really don't like it and didn't buy the game for that purpose, so I cannot say if it crashes there.
I have attempted cleanly reinstalling my drivers, and I have even reformatted and reinstalled my OS. Nothing seems to help. ARMA is the only game that I own that crashes like this. It does not happen on any other games.
After browsing this feedback forum for awhile, I see that this is a common theme. It seems like every page has at least one of these reports about random crashes. Please begin to consider that this is not entirely a user issue, and that your game may have some yet unresolved stability issues.
Thank you for your time and attention.
