Hello all. I have an annoying problem which I was hoping someone could help with. When I run Railworks with TSX turned OFF I get a problem where the image 'flickers'. Pretty much everything disappears off the screen for a split second then everything goes back to normal. The problem happens in all trains and on all routes. I can't think what it could be Heres a video. It happens at about 19 seconds. http://www.youtube.com/watch?v=j0I7u8jNku8 Any help or advice would be good. Thanks.
