40d Talk:Maximizing framerate

Effect on # of dwarves, framerate calculations

I'm not sure how important the number of dwarves is on the framerate. I was getting about 12 to 15 with 22 dwarves, and this has fallen to 9 with 97 dwarves. I think it is more bad pathing, like animals being caught behind doors that causes more problems than the number of units themselves. The addition of 80 goblins had an impact of 1 fps as well... although again, they probably weren't having any trouble path finding to no where. --Gotthard 13:53, 3 December 2007 (EST)

I typically see a substantial drop in framerate when new immigrants come, and afterward the game's never as fast or responsive. However, I also demand a higher framerate (not less than 40, to avoid annoying interface lagging/jerkiness) than many people seem prepared to tolerate, so our findings aren't inconsistent. You just have more load already and so don't notice a given amount of additional usage as much. Fedor 05:39, 7 December 2007 (EST)

If this is the case, then I doubt there is a linear relationship associated with the FPS values. The G_FPS might also impact this. Typically, 10-12 more dwarves lowered my FPS by 1 at max, and I have 6 masons making blocks for my castle, and 18 dwarves running around permanently putting them up. I would guess that the FPS drops off fast to begin with, so it takes a lot to go down from 10-9 fps compared to 40-39 fps. --Gotthard 08:35, 7 December 2007 (EST)

Yes, this is expected. Framerate changes aren't linear and here's why: Let us imagine that a given computer can process 10,000 game things per second. A framerate of 100 means that the game requires only 100 calculations per update, and therefore can update 100 times/second. A framerate of 1 means the game has to perform 10,000 calculations per update. To drop from 40 to 39 FPS, the game must require ~6 more calculations per update. To drop from 10 to 9 FPS, the game must require ~111 more calculations per update. Fedor 08:51, 13 December 2007 (EST)

Weather and Trees

Is it just me, or with weather turned trees will not grow back. Most saplings have withered and died. The landscape is littered with them. I'm in a Mirthful area, so it's not alignment. I haven't been able to get any trees since I deforested the entire area, and yes, it has been over three years. I'm playing 33d. Klada 19:50, 5 December 2007 (EST)

Well I've been playing map for 6 years now, and I've had weather on the entire time, tons of trees have grown back. I've not deforested the ENTIRE area, but from what I understand trees grow back at a proportional rate to the amount of area there was to grow, so it should be better. I think saplings randomly die, perhaps moreso with traffic on them but... I don't have an explanation. --Gotthard 19:23, 6 December 2007 (EST)

"Is it just me, or with weather turned trees will not grow back." Turned on or turned off? Logically, if weather were turned off, trees shouldn't grow to maturity.

Economy

Can we confirm/disprove the effect of the economy on framerate? --DDouble 02:42, 13 December 2007 (EST)

Not sure what you mean exactly. The economy makes several changes, any of which might potentially impact speed. Can you give more detail on what specifically might potentially be causing a slowdown (or speed boost)? Is there a discussion on the forum that you have in mind? Fedor 08:51, 13 December 2007 (EST)

I'm pretty sure he's talking about the init setting and turning it off. The 'potentially' part you mentioned is what he wanted clarification on. Does turning the setting off before the economy activates improve pre-economy performance? There might indeed be people out there that are willing to lose one of the cooler features for a much improved framerate. A good question is does turning that setting off prevent you from ever gaining an economy (when you decide to turn the option back on) should you pass the point where it should have activated? --n9103 11:27, 17 Dec 2007 (PST)
