Designating causes lag? o.O
Fensfield:
So, I have two big projects on in my fortress. The first, is the hollowing out of a large, square chasm, from layer below the surface, to the lowest level of the map, around a kind of internal 'central tower'. Normally I'd cave the whole thing in, however, unfortunately there are some important gubbinz on level -11 that cross the chasm, so I'll have to carve around them until -12. Besides, my entry tunnel overhangs before bridging into the tower, and I want to carve out some nice support strut-y things under it.
Anyhow, the other project is a four layer deep cistern inside the middle of the tower ( the aforementioned gubbinz is its aqueduct ). At the moment, its busy filling ( just beginning to fill level 2 ).
As you can imagine, my game is presently lagging rather heavily. Population of nine dwarves, and four animals roaming free, and at present my FPS averages at 35. .. And I've just noticed something weird.
On completion of the last layer of digging, my FPS sky-rocketed to 98~100 despite the water still flowing into the cistern, only to plummet once more once I'd designated and set my four legendary miners to work on the next 35x35 or so wide layer of the chasm ( -9 ).
So.. designating/mining out a large-ish area causes significantly more lag than filling a chamber with water via a 3 layer drop, from an underground river across the map? o.o;
smjjames:
Yea, it does that for some reason, and is mentioned on that thread about improving FPS.
Although it takes quite alot of designation to badly affect the FPS for me, a 35x35 layer of designation hardly affects my FPS.
Also, the water filling your cistern will reach a point where it starts hitting your FPS.
gtmattz:
I have found that the more areas of the designation that are accessible the more FPS hit you receive. For example designating a tunnel to be mined 5 tiles wide by 60 long doesn't do much to my fps at all, but designating a 5x60 strip of ramps to be dug out of the exposed ground will knock the FPS into the toilet. I am assuming that this is because the miners have to figure out the one out of hundreds of available digging locations is the best for them to dig at that moment.
Rowanas:
This relates to something I'd like to ask. My FPS is always around the 30-40 mark. When I designate huge areas for digging it's 30-40. When I have 50 dwarves it's 30-40, when I have 7 dwarves it's 30-40. My fps cap is set to 100, but no matter what I do, it refuses to budge from that range. I'm pretty sure this is impossible, so what the hell is going on?
Derakon:
GTMattz: remember, jobs pick dwarves, not the other way around. So when you have lots of exposed minable squares, you have a lot of digging jobs saying "Hey, is there a dwarf available yet? How about now? How about now?" And each time the game has to go through its list of dwarves and discover that all of the dwarves with mining turned on are busy.
