1.23 Why do taxiways disappear and then reappear as you align?

From FlightSim

Q:

HAS ANYONE ELSE NOTICED TAXIWAYS MOMENTARILY DISAPPEAR, THEN REAPPEAR AS YOU ALIGN?

A:

It's not only your system but mine and I'm sure others as well. In fact, there are places in FS98 where some taxiways are sort of "now you see them, now you don't" and I'm not certain whether the phenomenon is one in which a base scenery from a prior version of FS still remains, and where MS took the easy way out by designing right over the old....sort of like paving over an old road surface. The phenomenon you describe can be attributed to the rendering engine in FS98...that change in view or direction means that the program must do a redraw with entirely new coordinates and a lag in time is noticeable as the computations are done and the new polygons put down. At a distance this never is a problem because the view changes are relatively small, so an entire redraw isn't' necessary....but on the ground the problem takes on a whole new meaning.
