You can use multiple cores, but the program still has to wait for each individual data process to run through, so it can't do 2 things and evaluate them at the same times.

But I thought the whole thing about DF not be multi-threaded was that is was only doing 1 thing at a time, so this brings me back to my earlier question. I would have thought this should clearly mean it could use 100% of a core or if it can share a process between cores then 100% of both cores.

Just genned a world that I really want to take a look at, but it always crashes when trying to export the site+biome map.  I've had several worldgens do this.  Anyone know of a workaround?

I had this problem but then it appeared I could load it up anyway, I'm not sure if it was crashing but saving it anyway or I was loading the general map info export you choose when finishing the worldgen before going to legends mode. Hope this helps, I never managed to stop it crashing.

OK, so from what I gather, dwarf fortress not really being multi-threaded means it should only use 50% of a dual core proecessor, 25% of a quad core, etc. If this is the case I assumed it meant it could only optimally use one of the two cores, hence the 50% speed. If that is the case why the heck is dwarf fortress using 50% of both my cores? I am really confused, I have checked with task manager and third party programs and they are definitely telling me it is using both cores. As this is the case I don't understand why it can't use 100% of both cores. BTW, this is during worldgen though I assume it is the same during fortress mode (I will check when I manage to cancel this current worldgen I am half a day through).

My second question is, I have recently bought a quad core processor that is only about 20% faster than my current dual core, I assume if I install this Dwarf Fortress will actually become nearly twice as slow as it was with my dual core, would it be a valid idea to try and get some second hand components and build myself a cheap/lo-tech rig just for running things like DF. Would this rig be noticeably faster for running DF than a modern multi-core machine. I assume all I should focus on for this goal would be a modern-ish single core processor and at least 2 gigs of ram (4 if I use a 64 bit OS and the LAA patch).

Thanks in advance for your help.

I'm not the most intimate with computer workings, but isn't the main issue with DF processing speed, not really the memory size?  Does this change have any worthwhile effect on speed?

I believe many people are having trouble with worldgen crashing on large worlds or particularly long histories as they RAM usage of the program is exceeding 2GB. This is the default upper limit for a normal windows program I think, hence the crash. The file in the OP flags the EXE so windows "knows"(?) the program can use 4GB of RAM (3GB in XP) and won't crash when the normal upper limit of 2GB is reached. I'm pretty certain it should have practically no impact on the actual speed of worldgen as that is pretty much exclusively tied to your CPU.

Skyrim had a similar problem when people started installing loads of custom high texture packs etc, hence the Skyrim reference in the OP. My knowledge of the specifics is a bit ropey too so take the above explanation with a pinch of salt. I do find it hilarious that the new DF with it's super high fidelity graphics  is having the same problem as Skyrim though. All hail Toady, Bethesda needed mods added to achieve this.

Edit: Kind of missed the point there didn't I. I don't want to contradict the author but I kind of agree that Dwarf Fortress game speed is not very RAM dependent as far as I know. I assume it should help with large embarks/adventure mode area transitions and things though, basically anything where the game is loading lots of information to and from memory rather than simulating tantrums/combat etc.

Edit 2: Hope I haven't made a fool of myself sounding like an expert when I'm not. Anyway, just wanted to say thank you very much for posting this Anticheese, it is just what I was looking for.

I had a tortoise demon with deadly blood too who also tricked a civ into making him their leader in year 6, he initiated many wars but still didn't even come close to the kill count of your example.

I also have a dragon, Ral Torridjewel who has survived for 550 years, he only has 257 kills but his enemies list is 13 pages long! I guess he's less feared and more loathed. Also he is the last living ancestor of the ensuing "dragonsplosion" that has occurred on that world. There were two other males and 1 female who have all died now but all of them had offspring and I have currently counted 10 children (dragonlings) between them and at least 33 grand children. Ral has had 20 children and grandchildren himself. I haven't even had time to explore more generations down. The poor world has been plagued by dragons since year 1 by the looks of it. Once the new legends viewer is available I will be sure to post an update. Trying to track all this right now is giving me a headache.

Woop! Thanks Dwarf Engineer, I really don't think I would have had the faintest idea what I was doing if I tried to fork it. I also agree with people saying that features aren't essential, we'll all just be happy to have a playable fort mode.

Hi, I'm kinda a new to the boards but you can count me in. Have joined the steam group and am ready for an invasion.

Breaking from lurking to just say, Woo! and Yay! and that if this all runs smoothly you have probably secured my first donation. Love how quickly you got all these fixed done, GJ Toady.
