As a former YSFlight pilot, I feel like the only thing FlightGear is missing (besides from the many things that YSFlight doesn't have) is the shadow on the ground. When I'm coming in to land, it used to give me the approximation of the height of the plane.
(Yes I know, FlightGear has much better graphics than YSFlight, but this picture is just to show you the shadow effect)
I did try the full 3D shader effect, but that dropped my frame rate to 1 fps.
Is it possible to do a simple, 2D shadow of the plane just on the ground? I don't think that should require much graphics performance, does it? If it's not possible, is there a reason why?
Just wondering.
