Summary

0003532: worn blood splatters decrease game performance by 400%

Description

my fort, 6 embark tiles, 3 caverns, 130 dwarfes, 330 pets, used to run on only 8 FPS on a 3.5 ghz core i7, when i tried to get rid of blood carried around by dwarfes and pets by using the dfliquids and dfcleanmap tools. after placing some water around important routes and running the cleanmap utility in a loop, performance went up to _33 FPS_. thats more than 4 times as fast... this truely shows that the algorithms for the blood and dirt splattering are very inefficient, to say the least.
the switch in the config file ("do not move splatters around") seems to be completely failing, it was enabled all the time, but did not prevent up to 100 different blood splatters on the single beings.
