Well, my first Genesis fort came to an end. Not because of the simultaneous sieges before I had the iron industry underway, but because my FPS dropped to 1(1) when an entire z-level caught on fire. 
The bushfires, even on 3x2 embark, tend to drop the fps, especially when they touch frozen pools. Just let the game run 1-2 hours while you do something else, the fps will climb back up after the fire is gone.
ps. don't store logs, coal, coke, lignite outdoors.
Can sum1 please tell me the difference between the tilesets?
