OS X Graphics problems in Assassin's Creed 2

[Xer]

Hi guys!
I recently purchased Assassin's Creed 2 for Mac on Steam.
When I play, lots of times I get hiccups / lags in the graphics while playing (mainly when moving the mouse).

I tried lowering the graphics to the bare minimum and it still happens.
I'm playing on a Late 2013 iMac 27 with the 3.4Ghz i5, GeForece GTX 775M 2GB, and 16GB of RAM, so graphics shouldn't be an issue here.

Anyone know anything about that?

Thanks a lot

Unfortunately, AC2 under OS X isn't that great. If you play under Windows, you'll be just dandy–but for OS X you're going to be dealing with the lag every time you play.

I see.. that's a shame
Thanks a lot for the answer
