I know my computer is no speed demon... it's a 1.2 ghz G4 iBook w/ 768mb of RAM, and a 15% or so overclocked Radeon 9200 in there w/ 32mb of RAM. This is not a speed demon, but generally speaking, this is not a bad computer. And OF COURSE, according to the Sim City requirements, this machine should tear right through this program... haha, and to think that on the box they say it can be run with a 500 mhz G3. I'd like to see that... Okay so I think you all know what i'm getting at. Is there some big tweak i'm missing in order to make Sim City 4 NOT suck ass speed wise when the city gets big? Let me know... -Kevin P.S. I REALLY like this game... I wish this didn't happen!
