I've never encountered any performance issues on Dwarf Fortress, however, none of my forts have ever had a high population then say... 20 total critters. (Including dwarfs, cats, dogs etc etc). Based on the specs listed below is there anyone that could gage my computers ability on handling larger forts with like 50 or so plus dwarfs?

Processor: AMD Turion 64 X2 TL-60 2.00GHz
Ram: 3.00GB
OS 32-bit Vista
Video Card: ATI X1250 (128MB Pixel Shader 2.0 Vertex Shader 2.0) -- integrated

I've tried doing Adventure mode where I encounter a slight lag.

The best way to answer your question is to try, getting ~50 dwarfs is easy, if you set up a proper economy you'll be flooded with migrants within a few hours of gameplay.

My computer has a similar processor speed, although I don't know how AMD differs from Intel. With ~50 Dwarfs, I don't get slowed down to the point of unplayability, I think. I can't remember the last time I got 50 dwarfs, and I certainly haven't on .31.xx yet, because I've not yet really worked at a fortress on .31.xx. Still, from what I remember of 40d, I didn't get horrible slow down.

I thought (for awhile) that the caverns were eating up fps on .31, but then I realized that I had modded 40d with [SPEED:1] and had yet to do so for .31. So... yeah.

It really depends on what you consider as lag.

For some anything below 50 FPS is considered lagging. Whereas I have seen threads where the player has only 2 FPS and still continues playing.

I think your PC will be hard pressed with 50 dwarfs (25 FPS and below) but it also depends on a couple of factors:-

1) The size of your embark, 5x5 is a killer, 3x3 or 2x2 might help;
2) The number of z levels you have uncovered and dug. The more z levels and rooms the more lag you will encounter this is due to the pathfinding issues;
3) The number of roaming animals you have, the more you have the worse it will be;
4) The number of items you have, more bins, more barrels, more items, more anything makes it worse.

Good luck

Hey, same specs and i get 15-20 fps at 70 dwarves.

Anything above 8 is great in my book, thanks, most of this is all reassuring.

5) the number of ambushers/thieves on the map.
I found the "are we spotted yet?" checks to be a huuuge drain on FPS too.
