I don't know if this post is necessary now that I read Frogboy's post on the day 0 build, but just in case....

What I did was, in order to test performance and the AI, I ran a small map with the fastest game speed, and all I did was continuously build up my one city, research tech and spells, get the resources around my one city, and see what the AI would do.  I played 297 turns, got my city to level 3, researched about 3/4 of the way through the tech tree and I was only attacked a couple times, but never truly challenged.  The AIs were fighting amongst themselves and several AIs were destroyed but for what ever reason, nobody bothered with me.  Now this might all be different in day 0 so...

Also I tested performance just constantly viewing the one city as I built it up... started around 40 fps and steadily declined from there.  When I got the crash on turn 297, the fps when viewing the city was 6 fps.  It's weird though, it's a steady smooth 6 fps, not stuttering at all though...

Then I got a CTD on turn 297 for no explicable reason.

Here's the dump and the debug:

Here's to the 0 day version being the game I waited 2+ years for!

Edit: this needs to be in the support forum, sorry...
