Mine's been crashing at random I never know when it's going to do that and it just stops without any explanation says ARMA 3 has stopped working and makes a file then I save it out. I have quite a few of those but have never done anything about it. Think maybe it is a memory problem. Thought I would see if there's anyone here who has any ideas what the cause of it is. Booted up fresh start of the day to finish a mission to share on Steam and made some changes in the editor to the mission and boom! down it went. Lost all my changes.
I run a pair of Z97 computers on my LAN custom built. 16 gig of RAM. Nvidia 970 video cards. SSD on my C / OS drives. Very fast. Windows 10.
