@anathema btw this is a 5x5 fortress which does get laggy on some computers once you reach high populations. i used to play on 3x3 fortresses at half speed on my t450 to avoid lag, but that was before multithreading. im not sure how good ur laptop is but if it is getting laggier i'd recommend using dfhack it has multiple performance plugins specifically fast heat and timestream. ive been using dfhack but with most gameplay plugins turned off. it adds a lot of good qol ui elements as well
