Not amused, Apple. Bought the top of the line iMac with top of the line hardware (what they offer, anyway). 3 ghz, 4 GB RAM, 512 MB nVidia, 1 TB HD. Set up Bootcamp (Windows XP, not Vista), load up Wow and set the settings identical. The pictures speak for themselves: Mac: http://img368.imageshack.us/img368/3163/picture1pg7.jpg Windows: http://img368.imageshack.us/img368/7148/wowscrnshot050408041332eq4.jpg Can someone explain this to me how there can be this drastic a difference rendering the same exact scene with the same exact settings on the same exact hardware? Problem with Wow? Drivers (what I'm leaning to)? I mean, a 3x difference is definitely notable. (And for those about to ask: Spotlight was done and Time Machine wasn't backing up. The only thing running on both sides was Wow).
