I bought this game a few days ago and have been playing it on-and-off. When I do get a chance to play it, the graphics will occasionally flicker, in a sort of multicolor static. On top of that, I can only access 800x600 and 1024x768 resolutions, and not 1024x800 & 1600x1200 like the manual claims I can use. So I'm guessing my computer's graphics hardware and the game don't get along (I don't have a designated card, just Intel's built-in graphics). Any ideas for a fix?
