I have a friend who has installed it on my system until he gets a video card that can deal with it. He's having the same problem, but at the same time isn't really all that bright at times.
Not a helpful post. Mabye I'll sit down with it a while and find out for myself. My problem in Sim City (well, 2000 at least, being the last one I played heavilt) was expanding a small profitable city into a larger one without hurting the econemy too much.
