I haven't been able to play ArmA for more than 30-60 minutes in about a year now. I tried all the fixes such as disabling full screen optimizations on exe's in steamapps, changing memory allocator to Windows, using Win 8 compatibility mode, running SFC and DISM checks, etc...
I finally just decided to re-install the entire system the other day.
Fresh format, reinstall, newest drivers, very little non arma related software running. Still crashing, same error #.
There has to be some common denominator here with all the other people having this issue.
I'm running on:
Intel I7 4790K
Logitech gaming software for G510S keyboard and G600 mouse
Drivers for Thrustmaster 16000m and Throttle
Tight VLC server
