0005629: massive drop in FPS, seemingly related to INVADERS:YES setting in d_init.txt

Notes
(0021444) Footkerchief (manager) 2012-03-13 08:49	Reminder sent to: robertheinrich Please upload a save demonstrating the lag to http://dffd.wimbli.com/ [^] The lag may be caused by dwarves trying too frequently to detect sneaking ambushers or whatever.

But this is the first time that happens for me, I´ll forward that to the dfhack thread in the forums. - After unrevealing the map the fps recovers, but not to it´s maximum. To confirm that I have set the max fps to 200 (since the standard setting of 100 was not obvious enough if it only drops to 80). On my system the map runs with solid 120-150 fps with INVADERS:NO and only 75-80 fps with INVADERS:YES - I let the map with INVADERS:YES run for a while to see if it recovers. A werebeast arrived and was killed by my military. Afterwards the fps went back to normal (around 150 fps when most dwarves are idling around), no matter if the map was revealed or not. I have uploaded both saves: 1. fps drop with invaders turned on, massive fps drop if map is revealed. 2. same map after some werebeast was killed, no fps problems anymore regardless of revealed map Here´s the save (actually a full install since I thought it might be easier to test because I use Phoebus and dfhack): http://dffd.wimbli.com/file.php?id=5873 [^]

No invaders on the map. Edit: I let the map run for a while (with invaders enabled) and a siege of ca. 20 undead humans and goblins arrived. Very untimely by the way because I only had 32 dwarves and almost no wealth yet. So together with the other map where the fps would drop before a werebeast arrived it seems that fps goes down quite a while before invaders actually arrive on the map. And it might just be bad luck, but it´s the first time I had a siege with 20+ invaders arrive in the second year while having way less than 50 dwarves and almost no wealth.

(0021505) Footkerchief (manager) 2012-03-16 07:47	Do you have a save that demonstrates this problem without reveal ever having been run? The use of third-party utilities kinda voids the warranty.

(0021513) robertheinrich (reporter) 2012-03-16 13:02 edited on: 2012-03-16 13:05	Unreveal should revert the game map to the original state (i.e. before reveal was first called). While I see where you are coming from regarding never using memory-altering tools - vanilla DF is almost unplayable without them. But for the sake of this bug report I will try to create a completely untouched ascii fortress (when I feel masochistic enough to do that) and check if it occurs there, too.
