Hello,

I recently updated from 34.11 to 40.11 and I've noticed a huge drop in FPS overall. I've done everything on the wiki to improve it, and also read other similar postings on this forum... I have no idea why but I get to about 100 dwarves in a 3x3 embark, no cavern, minimal construction queue, no temp or weather.... I think the FPS has finally dropped to 20 and continues to grow worse. Had much bigger and higher population forts in the older version and could maintain much better framerate. Just wondering if this is a common issue. Love the game, thinking about actually upgrading to a better computer now. Any suggestions would be very appreciated.]
 I have a fairly modern laptop: AMD quad core A6-3400 with TURBO CORE: should go up to 2.3 GHZ, 6Gig RAM.

Sorry, I made a mistake. i'm actually using 40.10, not sure if that would make a difference anyhow.

Like you said, there's been a bunch of threads about this already - http://www.bay12forums.com/smf/index.php?topic=143147 for example. That should indicate that it's quite a common issue.

Also, welcome to the forums!

Thanks. I wasn't trying to beat a dead horse by posting this, but I only saw maybe one or two other posts that were similar. Hoping for specifics, but didn't know completely for sure that it wasn't just my computer.

Also so you know, Dwarf Fortress only uses one core so your total of 2.3 GHz (even by regular game standards that do use multiple cores) is really not much.
The 2.3GHz that you have are basically divided by four since you have a quad core, so dwarf fortress uses 0.6GHz on your machine.

But I agree though that the game uses a lot more resources now, on a 5x5 embark on my 5th year with 180 dwarves the game runs at roughly 20 FPS.

Nice joke.

How is that a joke?

I haven't been computer shopping in a while, but usually the clock rate of each processor is given. What he has is 4 2.3 Ghz processors I imagine. I never heard of anyone adding them together for some kind of cumulative Ghz. I have been out of the loop for a while I must admit.

No, clock speed is the total of all cores combined.
So on a 4GHz quad core CPU each core in the CPU would be 1GHz. Speeds are always CPU speed, not core speed.
Processor frequencies are different for each core so 2 could run faster than the others but basically having a higher clock speed dual core processor would be better for Dwarf Fortress than an equal clock speed quad core.

It uses 2.3Ghz, as each core has 2.3 Ghz.

"Speed", or better to use the word "frequency" in this case, is not something that you can divide or combine. The clock operates at some frequency (actually, it determines this frequency) and it doesn't matter how many cores you connect to it, they all will operate at that frequency.

What you were right about is that faster CPU with less cores is better for DF than slower with more cores.

Merc,

How big a world did you gen? Unlike previous versions, 0.40.xx keeps track of everything going on the world, while you play. I find Medium and Large worlds unplayable at the moment. Consider genning a "Smaller" or "Pocket" world, see how that works out.

Yeah, no, that's not true. Seriously, Atari tried pulling this with the Jaguar back in the '90s calling it "64-bit" which was just additive and they got a huge amount of shit for it. Clock speed is for all cores individually.

Hey, I just updated to 40.11, on the same computer, and I'm back to averaging 90 FPS!

[bluephoenix]

Oh damn, looks like I need to read up on CPUs again. Sorry for giving out the wrong information.
