For Mac unusable!

The settlers are among the best games series. And finally for the Mac, I thought. But unfortunately it has been ported with cider and so is the performance badly. Even on fast Macs is at best graphics like Settlers IV (only now in 3D) in there (at reduced resolution). And many features are not supported on Mac. Strangely, running on the same Mac under Boot Camp and Vista the game at the highest resolution and medium details absolutely liquid ...
Please rectify necessarily, because it is absolutely not a "Mac-Ready" game !!!

I probably need to copy anything to say ...
