I did try the ArmA2OA.cfg thing and it helped a little but it's still not much of a jump. At least now I can turn a bit more smoothly. Again I realize that I don't have a gaming rig so I can never to expect a smooth framerate but when my buddy, who actually has a gaming rig, is barely getting 25 in the forest and country and >15 in the cities, there's something wrong.
