Ok just to make this quick. I run exactly the same computer settings and specs for the other DCS World versions with not one issue, thats with GTX 780, 16 gigs DDR3, I7-950 @ 3.65, and latest driver and basically the same settings . So now I'm in DCS 1.5 which visually is stunning but I have stutter problems using the flir and schval (spelling) and the weird see through vehicles bug. And no 3D or Occulous. I don't think there is much more to say. I understand that some people miraculously have no problems but a very large number are having them. I just wanted to let you guys know that I to am having the problem.
