Start up DayZ and change everything to low and turn off and extra features. Then open your Arma2OA profile (should be located in my documents) and change the scene complexity to 100. Then open ArmA2OA config file (should also be in My Documents) and change what GPU_MaxFramesAhead equals to 1 and what GPU_DetectedFramesAhead equals to 1. I suggest using DayZ Commander. Hit settings, then launch in Windowed mode. Just stretch the screen to fullscreen. It might not look very nice but you'll gain about 15fps from doing this.
