Summary0005003: Some Maps Run Super Fast - Some Super Slow
DescriptionI have 2 maps currently saved.

One is a Medium world where I have a huge fortress with 70 dwarfs and a huge underground mining complex. It runs perefectly at 100 FPS with no slow down at all.

I made a Small world where I have 7 dwarfs and a tiny fortress. This ran at 20-30 FPS straight from starting.

I have a good Quad-core PC with 8 Gig ram. The slowdown is the same with all tile-sets and FPS settings on the small map, but perfect on the medium map.

Could this just be a random bug with the world generator?

There was a "Cave in" message as soon as the game started. Could the game be calculating cave in mechanics behind the scenes non-stop?

Steps To ReproduceNot sure!

There is probably an underground waterfall, that is, water in one cave level draining into a chasm and off the map in the next cavern level.

dfhack can be used to reveal the map and check for such occurrence.

The bug aspects of this are covered by 0000051. Aside from that, it's expected that some maps will run faster than others due to environmental features (especially falling water).
