I've just recently bought Civ 4 for my PC and it apart from a bit of lag here and there it works fine. The only thing wrong with it is that when I play a game, the landscape is in darkness. I can see my units, cities and improvements fine (I can sometimes catch glimpses of the fishes in the sea) but the entire terrain is shrouded in darkness. So far I've set the graphics to medium but it's had no effect. Something else that's happening is that the portraits of the leaders aren't really visible and all I ever get is their eyes, mouths and hats. Is it something to do with my PC or do I need to make a change in my display settings? Thanks if you answer!
