I tried out the new RC 1.40.129525 thoroughly by playing a few showcases and then the last Campaign Prologue mission. Moments after starting the mission seeing the helicopter coming toward us I suddenly got an APPCRASH C0000005 ACCESS_VIOLATION at 01CC4690 01:00EB3690 S:\games\steamapps\common\Arma 3\arma3.exe

Other than that, the RC was very stable under high system load. {F25687}
