'''OS'''

:* Operating System: Requires Windows NT 4.0, Windows 98, or newer

:* Non-Windows OS: Linux using Wine, no current native Linux version, no current release for Mac OS. (both in the works)

:* The [[40d:System requirements|40d article]] has detailed info on Non-Windows OS' that is probably mostly still valid.

'''RAM'''

DF is not particularly RAM-hungry. With 512MB you may be a bit on the short side, but 1 GB is absolutely sufficient. World Generation can eat up far more than that, but Generation will only be slower if not more RAM is available. Otherwise the influence of RAM on game speed is limited, as DF is not loading and offloading big chunks of data much.

There are no detailed requirements per se. However, because simply saying the more RAM you have and the faster your CPU is the better is not all that helpful, here are some stats that users have experienced while playing this game on a variety of different environments. (Please note that ‘fast game-play’ and ‘slow game-play’ are subjective terms and not intended to relay anything specific or exact. What may be fast to one person might be slow to another.)

'''System''' : Result

'''P4 3.0Ghz with 1GB of RAM''' : Slowish

'''Dualcore 2.0Ghz processor with 2GB of RAM''' : Fairly slow

'''Quadcore @2.3Ghz with 3.25 GB of RAM''' : Fast

'''AMD 64 2.2 Ghz with 1 GB of RAM''' : Slow on maps with lots going on. Okay, but not great speed (~35 FPS) with Partial Print set on and temperature and weather turned off. It is playable until population passes ~80.

'''Intel Pentium 3-S Tualatin 1.4ghz with 1.5GB ram''' : Very slow but playable (~7FPS)

'''AMD ATHLON XP, 1.7 Ghz, 1 GB RAM, Win XP''' : Fairly Fast (~40 FPS)

'''AMD Athlon X2 dual core, 2.2GHz, 4GB RAM''' : Fast (~80FPS)

'''Intel Atom N270 1.6ghz HyperThreaded, 1GB RAM''' : Slow but Playable (12-24FPS default, 35-100FPS with PARTIAL_PRINT set to YES)

I couldn't find the Mac OSX version of DF2010. Is there one? --[[User:Calculator|Calculator]] 17:29, 7 April 2010 (UTC)

:Not yet. After a few bugfix versions, (and obtaining some new RAM for his computer), Toady One will of course release versions for other OSes, but for the initial wave of bugfixes, he wants to limit it to one OS, for simplicity. I'd say between two weeks and a month before we see OSX and Linux versions. --[[User:Zombiejustice|Zombiejustice]] 18:09, 7 April 2010 (UTC)

I am trying to run the new version, but the game is painfully slow (especially compared to 40d). My computer isn't that out of date, so I was wondering what specs are recomended? --[[User:Frewfrux|Frewfrux]] 22:43, 7 April 2010 (UTC)

:Can't really give any solid recommendations, but I can share my findings between my machines. A 3.0Ghz P4 w/ 1GB of RAM ran the new version a little slower than the old. Another machine with a dualcore 2.0Ghz processor and 2GB of RAM ran it even slower. And my main machine, a quadcore @2.3Ghz with 3.25 GB of RAM ran significantly faster than the old version. These very simplistic tests were done with the same world --[[User:Kuroneko|Kuroneko]] 23:45, 7 April 2010 (UTC)

::Hmmmmm. Maybe it's the RAM that makes the difference. And then, perhaps it's that I just keep not thinking of my computer as old. The processor is okay, AMD 64 2.2 Ghz, but I only have 1 GB RAM. It ran the 40d version great, except for the very, very full fortresses that were by a canyon. I wonder if anyone else can share their specs, and then maybe we can know what affects performance the most? Just a thought. --[[User:Frewfrux|Frewfrux]] 03:19, 8 April 2010 (UTC)

:::I've been curious to see what affect CPU cache sizes have on the game. It is painful but playable (I get bored at work) on my work PC which is the listed 1.4ghz tualatin (mind you, the game is only getting about 75% of the cpu cycles), but on my home PC (Q9550 @ 3.5ghz) is absolutely screams. If I get the time, I may try running the game on my old P4 box using multiple cpus at the same frequency but with varying cache sizes to see how much of an impact that has. I know the game isn't SMP aware (correct?) so a single fast core will outgun two slower cores in the game. As for RAM, I've seen the game use upwards of 800MB while world generating and under normal game play, for me, it uses between 400-500MB. So you may want to make sure you aren't dipping too heavily into your swap space when playing. That will definitely slow things down. --[[User:Helf|Helf]] 03:11, 14 April 2010 (UTC)

It might be helpful to add the fps achieved with each system. Although these are influenced by several settings, fortress size and location they might give a more objective rating than terms like 'slow', 'slowish' and 'somewhat slow'. --[[User:Hermano|Hermano]] 12:29, 13 April 2010 (UTC)
