Over the weekend, I played a large map with 9 Civs at epic speed. I'm playing on a top-of-the-line iMac (27" 2.93GHz Quad i7/4Gb/ATI 5750 with 1G VRAM) and had most of the graphics options at "high". Things were very smooth until about turn 490, when the game started to freeze every few turns (requiring a reboot). The freezes would happen when there was some kind of graphical transition (like moving the camera position a long distance or switching to a City overlay). Eventually, turning down enough options allowed me to proceed.
