I've tried limiting the population of my fortress due to FPS issues, but I couldn't find anything about population cap in the newest init.txt, although I know I've seen it before.

I tried adding the line [POPULATION_CAP:50] to the init, and I thought it worked at first as my population stayed at around 50-60... However, the newly arrived migration wave bringing my population from 65 to 83 obviously proves otherwise.

Has anyone had any luck limiting the population, other than using atom smashers?

The population cap works, but doesn't take effect immediately.  You may need to wait a year or so in game to see the cap prevent further population.  I always control my population cap, setting it down to 20 at the start and then gradually increasing the number as my fortress grows, but it's not uncommon to get a few immigrant waves at the start that push you over the cap.

Actually, my fortress is 5 years old and I've had that line in the init file since the beginning...

Now that's strange.  I've never seen a sudden immigrant wave after years of population at the cap.  Did anything unusual happen like your fort getting made a barony or something?

The first megabeast just arrived, although I guess that's a consequence of the population, not its cause...

A lot of the old init settings now reside in multiple files.  I believe d_init in the same directory has some, you might find the population cap one there.

[Cyntrox]

Ah, yes, there it is! In d_init.txt. I guess it's just a coincidence that I haven't been getting migrants these last few years, then...

Had my population capped at 100, and 16 more came in after 100.  Maybe the code checks to see if you are below the population cap then gives you a full wave, whether or not you go over?
