This is fifteen minutes (I kid you not) of real-time translated to a DF recording.
I've been trying to carve out a rather large space for the last four months, and it's pretty much all been at this speed. It actually takes quite a few seconds for even the designations to change frame, and about twenty seconds for the game to unfreeze after I hit pause. Yeesh. My laptop's heat vent spews flame.
Yeah, they're moving at SPEED:0. Can you blame me? In real-time they're still moving at speeds reminiscient of when I had 5 FPS, before I tapped the raws to get dwarven flash-step.
