oh no, it sounds like DFS (i'm assuming he's still doing AI work) need a good kick up the pants... again.
what i *think* is happening is the AI is leaking threads like it did in FA, to this day FA's unpatched AIs will invariably bring every (including yours) computer to a crawl.
[PROTIP:] DG is a P2P game, there'll never ever be dedicated servers, as there's no servers at all! that makes server management a non-issue, but it also means your game will run as fast as the slowest machine in the game (that's sim-speed, not framerate).
