Summary | 0001340: Walling off HFS kills FPS | ||||||||||
Description | This is apparently an old issue, but I felt it should be represented in the bug tracker :) When you release the HFS buggers and wall them off, the FPS drops waaaay too low. Once you open the way again, the FPS shoots back up. Footkerchief says "HFS has a tendency to spam path requests like crazy, even after you wall them off -- that's a bug that goes back to 40d and earlier," and links to several older bug reports back on the forums, here: http://www.bay12games.com/forum/index.php?topic=34311.msg1180616#msg1180616 [^] | ||||||||||

By the way, what is the policy for reposting known old bugs to the bug tracker? Is it generally encouraged, or frowned upon? Feel free to close this report if the latter. |

Encouraged, AFAIK. I think the original plan was to get all the old-but-not-obsolete bugs into the tracker ASAP, but with all the scary new bugs that need fixing, it's unlikely Toady will find time for transferring the old ones. Plus, it's usually not obvious whether they're still around, so it's good to get confirmation. |

This is a known bug, and can be triggered by plenty of things. I've done it myself with a caravan and a totally walled off depot. In the end I had to mod everything on the map but dwarves to only be able to breathe underwater, so they all died and stopped trying to find a non existent path fifty million times per second. |

May I suggest stickying this bug? Sorry for being obnoxious, but it is a very common and gamebreaking bug, only a little less bad than a crash. The FPS drops so low the game becomes almost unplayable. |
(0013997) Footkerchief (manager) 2010-11-18 18:21 |
I added a relationship to stickied bug 0000797, which is probably a worse offender (there are a lot of path-spam bugs). |

Thanks, that should be enough to make this report visible. |

This seems to be caused by the BUILDINGDESTROYER tag, which most probably never stops pathing. How to "fix" this issue, courtesy of SirPenguin from SomethingAwful (Gemclod is the name of the fortress): 1. Go into your init file and change the [COMPRESSED_SAVES:YES] to [COMPRESSED_SAVES:NO] 2. Start the fort, then simply save and quit again 3. Download DF World Tinker (http://www.bay12forums.com/smf/index.php?topic=67059.0 [^]) 4. Put that in your DF folder 5. Run World Tinker. First parameter, put in "GemClod". Second, put in "export". Third, put in "file.txt" 6. A file by the name of file.txt is generated in your DF folder. This contains all the raws of the active save file, which you normally cannot change 7. Open the file, and hit Control F "demon" to find the first demon 8. If you are Pozzo, or an overseer doing this, try to do this fast or without looking! You WILL spoil demon types, their syndromes, etc. etc. 9. If using Notepad, select Edit then Replace... 10. Find What: [BUILDINGDESTROYER:2] Replace with: (leave blank) 11. Now simply hit "Replace" until it says it cannot find any more instances of the tag 12. After you're done, save file.txt and close it 13. Open World Tinker again. First parameter, "GemClod". Second, "forceimport". Third, "file.txt" 14. "go", and it'll import your modified raws Repeat steps 9-14 with any other tag we deem beneficial. I found removing [LIKES_FIGHTING] seemed to add some performance, as my FPS rose to the 20s and then back to 16/17 when I removed it. But then it hovered around 15/16 again, so who knows. |

I can confirm this still happens in version 40.24. Going to try Jiri Petru's fix now, hopefully it will still work. Edit: No, apparently the program Jiri said to use hasn't been updated to support 40.24. Anyone know of another way to modify demons? |

I had this happen in an extremely noticeable fashion when I had a miner wall himself off thanks to channeling straight down and not completing an exit tunnel before he wanted to go on break. I had 100 (max) FPS (first Winter), which cratered to around 15 just having this one miner try to path to either his room or the dining hall. It may be relevant that he could hypothetically have tried pathing a climbing expedition up 100z of channel, but decided against it, only to consider it again multiple times per frame. |

I had this happen in 0.47.04, except that I didn't dig into the adamantine and then wall it off; I carved fortifications. And I didn't just get low FPS; DF froze for a few minutes and wouldn't respond to input during that time. The freeze started when the demons flew over to an adamantine spire (not the one that I carved fortifications in). |
