I have a top of the line FPS box with 2GB of RAM, max P4, double cache, 256 nVidia card, 60 GB HD and up to date BIOS and drivers. I use this box for my software dev job, World of Warcraft and FPS Wolfenstein. There is no faster box on the market, its whetstone and drystone numbers are max and this game is unbelievably slow on it. I have played Civ since it was a board game all the way thru Conquests. I like some of the concepts in Civ4, but the game is impossible to play. The 1.52 patch was an untested P.O.S. The 3D graphics add nothing to the game and even with the game speed at quick I can read a book in between turns. Either the algorithms they are using are linear and don't scale or there is some other serious software engineering problem with this game.
