I recently got a copy of SimCity 4 for Mac OS X 10.4. Since my Power Mac far surpasses the minimum requirements, I figured it should run quite admirably. But, it's far from it. It's really sad since the game performs better on my less powerful Celeron based Dell Latitude. The game is especially slow in larger, more populous cities. If it helps, I got SimCity 4 Deluxe for Mac. My Power Mac is a Dual 1.25GHz based system with 2GB of RAM and ATi Radeon 9000 Pro graphics. I'm also running the game on lowest graphics settings and a 1080p monitor, but the game does not run at that resolution, but Mac OS X does. Any ideas?
