I've tried reinstalling Windows 7 and 8 over and over again, used different nVidia drivers (Beta and normal), reinstalling the game, tried ArmA 3 Beta and ArmA 3 Beta Dev.
All drivers are up to date.
CPU usage when the problem appears is about 30%, RAM is at about 40%.
CPU and GPU are not getting over 40° Celsius.
All textures will start loading over and over again, the model will glitch into the ground and put the arms down on the sides just like the ChopperHeavy_lux_GetOut_H animation in the editors animation menu.
