I have the same problem. It's very random, but will happen 4 or 5 times during the course of 2 hours of play. It seems to always happen when I access the map. I have the m key mapped to my logitech G502 gaming mouse. I saved my crash report if you need something out of it. basic rpt: ---------------------- Process exit ---------------------- Exit code: 0xC0000005 - STATUS_ACCESS_VIOLATION Running time: 00:47:16.3152220 ---------------------- System information ---------------------- Date: 2016-04-20 18:20:50 / 2016-04-20 11:20:50 -07 Current dir: C:\Program Files (x86)\Steam\steamapps\common\Arma 3 Command line: "C:\Program Files (x86)\Steam\steamapps\common\Arma 3\arma3launcher.exe" CLR version: 4.0.30319.42000 OS Version: 10.0.10586.0 (Microsoft Windows NT 10.0.10586.0) OS 64 bit: True Process 64 bit: False Culture: en-US UI Culture: en-US
