Okay, for quite a while now I have strange phenomena occuring here. When looking at something moving fast, there is some kind of doubling effect appearing on objects, player plane and other aircraft including.



Here it is quite visible. I was actually suprised a screenshot was able to capture the problem. I think that has something to do with graphics settings, but I am at a loss here in regards to where to start looking. If any of you chaps might have a hand here in solving this issue I'd be most grateful. It is the only issue graphical wise I really have.
