I've also tried a bunch of stuff such as disabling that windows game mode, playing on 32bit, and disabling fullscreen optimizations.

I also have this problem, whenever I start Arma3, no matter if i connect to a server for Altis Life or just try the game in the editor - every time i enter a vehicle my game crashes. Sometimes its even enough if im close to a driving vehicle, sometimes i can drive a few seconds and then my game crashes.

I can reproduce the issue easily when just spawning a vehicle in the Arma3 Editor, no matter what vehicle. As soon as i start driving a vehicle is crashes.
Already tried various "fixes", validating my steam files, reinstalling the whole game, i have no mods whatsoever for arma3, tried it on a different computer even (same cpu, same gpu model), to no avail.

I figured it out, for me anyway. My headphones were causing it, so I disabled them and used Realtek HD Audio instead of my headset and it fixed it. I guess we'll just have to have a bit lower quality audio in order to play the game.

Hello.

Do you have all drivers up to date?

My drivers are, yeah. I even tried going back to a previous version on some.

HOWEVER; it works now. Thanks so much spike, what worked for you did it for me, too. Its unfortunate i can not use my normal headset anymore (which i really like), but at least Arma3 doesnt crash anymore in the editor when im using some simple in-ear headphones instead of my steelseries ones.

When I last posted here in january I kinda "fixed" my problem by using old normal in-ears whenever playing arma, and not my usual headset. Some time after, I happened to accidentally use my normal headset - and it worked, so I guess there had been some kind of update that actually fixed the issue.

However, since yesterday the old problem is back - whenever there is a car nearby or I start a car/heli/whatever, my game crashes. When im switching to the in-ears, it works again.

PLEASE, please fix that. What do I have a gaming headset for if all I can use in Arma is some 5€-in-ears?
