well i am facing this problem from long time i contact helpdesk but what they said that its due to limitation of video card.
To tell you i was playing trainz with intel graphics chip without this issue for 1 year and never faced this issue but it start arising so i upgrade my gpu to gtx 550ti 1 gb but cant even see a 1 % improvement but helpdesk says its normal and you cant avoid it so i was asking this to all of you that do this happens to you when there is a highly detailed view or when you sit inside a cab.i tried clean installation of trainz with out any thing installed but it still remains same
