I'm at 78 dorfs on a 6x6 w/brook, magma pool, and chasm, sand, and treez.  5 trading civs (7 total).  Especially during trading, this lags.
30-40 FPS average, 10-15 in spring and summer due to trader-clutter.  5-10 in siege.
Temp, Weather, Caveins off.
GFPS cap is 60, partial refresh on and set to 1.

My rig:
2.8 GHz AMD Phenom II X3 720 (Triple-core)
4 GB DDR2-1066 6-6-6-18-24 unganged dual-channel memory
512 MB ATI 3750 (600 MHz core, 800 MHz memory)
160 GB WD 8 MB SATA2 7200k RPM HDD
120 GB Seagate 8 MB SATA2 7200k RPM HDD


What would y'all reccomend I upgrade to improve DF's performance?

2.8 GHz AMD Phenom II X3 720 (Triple-core)

Well there's yer problem right thar.
40d isn't optimised to run on multiple cores. If you are planning on upgrading your computer, get a hyper-threading single core. That works best on DF.

[Tormy]

Huh, weird.... I think that you should have more FPS with this system, especially if temp, weather and cave-ins are off.
I have an E8400 dual core @ 3.6Ghz processor, and I have much more FPS with 80 dwarves, even when all features are on.

[janglur]

Oh duhrt, why didn't I think of that.

Woose1 was right.  I set ALL my stuff (including explorer and system processes) to run only on cores 0 and 1, and DF dedicated wholley as the only thing on Core2.

Runs about 2x as fast now.  Still slower than I like but a HUGE improvement


Edit:  Also, getting a single-core to replace a multi-core is really, really stupid.  More cores doesn't mean slower cores, it means MORE CORES.  Also, hyperthreading would annihilate my work apps, which lose a good 20% performance with HTs.  That's why we switched strictly to AMD after the Opteron came out.  Hyperthreading's a joke, and AMDs are extremely cost effective.
Bench on my 720 X3:  6788 seconds
Same on an i7:  6607 seconds
Not worth an $800 difference, not at all




Tormy:  What size map, how many animals, units, etc.?  And how many z-levels?
Remember, brook = huge loss.  chasm = huge loss.  Traders = huge loss.
Huge^huge*huge = Epichugeloss

On a 2x2 with 200 dwarves I get ~120 FPS, for example.  But what fun is that?
I need BIG MONEY, BIG PRIZES, IIIIII LOVE IT!

I'm now considering buing a PC with a Intel CPU because from what i've seen a stock e8400 is faster than anything AMD has to offer (for single threaded tasks).

Could you give any specifics as to what size is your fort, how many z-levels, features, etc.?

Also some info about te maximum map size to have ~100FPS with moderately sized fort (120-150dorfs) would be appreciated.

[woose1]

Well, it was my impression that you wanted to upgrade your computer. There's not much you can do with that. I was right anyways though. 

[Skelodwarf]

Wow, that's kinda funny. Dunno what changed it for me, but I only got down to 40-50's FPS zone at around 120 dorfs.

And I only have a dual core 3gig processor.

How do I go about setting things to seperate cores?

Or am I way over my head in my own stupidity here?

[Mr.Person]

You're using 40d11, right?

Lower your gfps cap. A lot. I have mine at 5 and everything looks okay. Keep lowering it until things start to look weird, then keep it there.

I'd like to know that too...

Hmm... Global Protection Fault System?

Your avatar looks so much cooler as your avatar than the original.

Basically you can use CTRL-ALT-DEL and right-click a process (under the 'processes' tab) and 'select affinity' and select which cores it can use.  Change is immediate.

However that's limited.
Process Explorer is a free download that can change affinity for ANYTHING, including the kernal itself.
