Got an base iMac 1.83 ghz model. I just installed bootcamp/windows and loaded up NHL 06, thinking that it wouldn't stress the computer at all. Problem is, the thing is extremely choppy in-game. Even with ALL the graphic settings turned down to minimum, the thing feels like it's running at 20 fps or something. I don't think that this should happen, since my old 1.3 ghz Celeron (512 mb ram, GeForce 5200 video card) could run it really smoothly with the graphic settings 1/3 up. At the very least, the iMac should run it twice as fast as my old computer....no? 1.3 Celeron ---> 1.83 Core Duo. 512 mb PC133 ---> 512 mb PC5300. Nvidia 5200 ---> ATI X1600. What could a possibly reason for this be? In my ATI settings, I even turned the settings bare all the way to "performance" instead of "quality" already.
