FS2002 Scenery Flickering

I just installed FS2002 and there is this weird scenery flicker. Whenever you pan around the plane in spot plane view the building momentairly appear and disappear making the scenery flicker. Some textures on the buildings flicker too. This only happens when you are paning around or flying. When you are paused and not changing the view it's fine.I have Geforce 4 MX4000 with DirectX 9.0c and 66.93 drivers. As far as I know my video card is functioning properly. I remember reading about some patch for Gerforce 4 MX cards but I may be mistaken. What do you think the problem is?
