I just updated my iMac and PB with OS X 10.3.2, and now Sim City 4 is unplayable! The region map looks fine, but as soon as I load any areas the terrain appears as if it is covered in snow. The problem is not that it's ugly, but that this "snow" covers everything on the map; zones, roads, etc. I've tried reinstalling and I can only conclude that there is some conflict with the graphics card drivers included in 10.3.2 and SC4. The odd thing is that my PB has an ATI card and my iMac has an nvidia card. Has anyone had this problem (or know how to fix it)? Is there a way I can revert back to 10.3.1?
