Heyall, There is a rather strange "fix" to this game. The windows client does run better, and if you run a boot camp partition to windows, the game plays flawlessly. A friend of mine in the game, showed me a website that, and I'm sorry to say, I can't find, but I will post when I get ahold of my friend. But it tells of a trick, where instead of running the Geforce driver, there's a program that will let you run SL using a Radion Driver. And for some reason doing that makes the game run smooth and flawless. No he didn't switch to radion on his mac, it still has the Geforce 8600 GT, but if you use the radeon drive, don't ask me why, but it works. I'll Send the URL as soon as I can find it.
