Nutter666 suggested I make a ticket here.
After ~50 units or so in my dungeon, I get pretty bad lag, and the FPS drops to <30. In addition, after 100+ units are in my dungeon, stuttering happens every 10 or 15 seconds. This happens in campaign or skirmish. The output log is from a large (largest possible map size), 4-player skirmish that was ~5 hours long before it crashed when I ordered all of my minions to attack. The lag was present throughout most of the the skirmish though.
Loading the game seems to alleviate the problem temporarily, but it returns pretty quickly.
