[40D] Processor Utilisation
« on: July 22, 2009, 06:45:08 am »
I had trouble finding anything about this. It seems dwarf fortress will only utilise 50% of my processor (or very slightly above that) at any time. The ini settings all seem to indicate that it should run at higher speeds with fps and graphical caps well above what I am getting.
It is Vista Ultimate 64, 4 gig ram and Intel Core 2 cpu.
Changing core affinity does not seem to help (infact makes it worse). No other games or programs have this limitation.
Is this normal experience?

DF lacks the programming to put multi-core CPUs to use. So, if it's only using one core, yes, I think that would be normal.

By the way, the fault may be with your OS. Vista sucks all the time at everything.

No. This post isn't helpful.

I agree with Urist. Steampunk is like Darth Vader winning Holland's Next Top Model. It would be awesome but not something I'd like in this game.

Unfortunately dying involves the amputation of the entire body from the dwarf.

I was going to post something here about Vista not being nearly as bad as the media made it out to be (I ran it from beta 1 up until Win7 RC) - but I won't.

Goblin pricking does not sound like it could pay well enough.

Ah. I was under the impression that it would act as one big CPU. Daaaaang.

Concerning "no other games or programs have this limitation" -- your other games must all be recent high-end games.  The majority of games are still, like DF, not multithreaded.

Yep, as a programmer, I can verify that it's about 0.003% as easy to implement as most people assume.

It wasn't so much I thought that dwarfs was multi-threaded or not, but that a dual processor could work together on a single thread. I should probably learn more about this.

Don't worry. The misconception is nearly absolute. Took me a long time to figure out exactly how it worked as well.

All we can do is hope Toady is bitten by a radioactive carp or something and gains massive programming super-powers.  ;D

You clearly don't have a vista :).
