After playing the Atlantis map (all slots full, vs the AI), the performance degraded rapidly after the 4th minute or so. Graphics were down to slideshow levels, sound was having the hiccups as well. Waited for a few minutes, didn't get better, had to exit. I'll have a few more rounds, see if it gets better, make a few reboots as well, I'll update later.
