40d:System requirements

From Dwarf Fortress Wiki
Revision as of 22:49, 5 December 2009 by Kludge (talk | contribs) (Removed "Recommended" section. Comparing a 1.4 ghz Core 2 to a 3 ghz Pentium is absurd. Changed wording around to veil the article's 2006 status. Some false/misleading info removed.)

If you're looking for information on improving the performance of Dwarf Fortress on your computer, see Maximizing Framerate.

General Requirements:

  • Disk Space: ~100MB. The game itself takes only about 20MB, but savegames and screenshots (if you take them) use considerable amounts of disk space. It is possible to use over a gigabyte of disk space with Dwarf Fortress.
  • RAM: 256MB. The game uses 150+ MB memory while running (more if you select a local grid larger than 6x6). The more creatures, objects, and explored space on your map, the more memory you will need. Most of this can be kept in virtual memory (page file), but be sure to have at least 500MB total (physical + virtual) memory available. World generation requires 400MB at its peak.
  • CPU: Dwarf Fortress is able to use as much CPU power as you can provide it with. While a Pentium II at 500Mhz is initially sufficient, your frame-rate will substantially decrease as your population increases, among other factors. Keep in mind that Dwarf Fortress will only run on one CPU at a time. There doesn't appear to be any indication that Dwarf Fortress will support multi-threading in the near future.

The larger your map and the more units on it, the harder your computer will need to work. The speed of the simulation depends on the size of the map, the number of entities (dwarves, pets, etc.), the number of levels (mountainous maps have more depth levels), the number of objects and other factors. Modern computers should be able to run 3x3 maps with medium-sized fortresses at 80-100 FPS. Particularly fast processors may be able to handle much larger maps at the same speed.

Other Operating Systems

Linux

Although DF is a Windows game, it works perfectly in Linux using Wine, as long as you have video drivers with working OpenGL acceleration – for all NVIDIA and newer ATI cards, this means using the vendor's closed source driver. Without 2D acceleration the game runs slow as Dwarven syrup. Most distributions provide Wine, so consult your distribution-specific documentation for help.

See this thread for tips about Ubuntu and other distributions.

On 24 December, 2008 Toady released the first native Linux version of Dwarf Fortress. It is compiled for 32-bit environments, however, and may not run under 64-bit environments without additional libraries, depending on the Linux distribution.

Ubuntu/Kubuntu

Under an Ubuntu/Kubuntu installation one first of all needs the ia32-libs package installed. This is a standard Ubuntu package that contains 32-bit versions of many common libraries. Unfortunately, while it includes 32-bit versions of some SDL libaries, older versions of this package lack SDL_image, which Dwarf Fortress needs. In Jaunty Jackalope (Ubuntu 9.04) this shared library is included in the ia32-libs package and you can skip the other steps in this section.

The 32-bit package can be downloaded directly from Ubuntu's package repository. Once the download is complete, open a console window and navigate to the directory containing the file. Extract the contents by typing:

dpkg-deb -x libsdl-image1.2_1.2.6-3_i386.deb ./libsdl-image

Copy the files from libsdl-image/usr/lib into the df_linux/libs directory and the game should now work.

If you have extremely low FPS make sure you have turned on your graphics card enabled in the Hardware Drivers.

Ubuntu/Kubuntu - Using getlibs

The other way to get the require SDL_image library is to use getlibs, which will get the correct 32bit library when run on 64bit Ubuntu and create all the required links.

At a command prompt: 

 sudo apt-get install ia32-libs getlibs
 sudo getlibs -l libSDL_image-1.2.so.0

The game can now be run from the df_linux folder (or wherever you extracted it to) using the df bash script.

Gentoo

The required libraries can be pulled from portage before running DF.

For x86, you will need the basic GTK/OpenGL/SDL stuff, plus sdl-image, which means the following packages:

  • x11-libs/gtk+:2
  • media-libs/libsdl
  • media-libs/sdl-image
  • virtual/opengl
  • virtual/glu

For amd64, you will need the 32-bit emulation libraries instead. Note that sdl-image is already included in the sdl emulation package, so you need:

  • app-emulation/emul-linux-x86-sdl
  • >=app-emulation/emul-linux-x86-baselibs-20081109 (earlier versions may not provide a 32-bit libgio-2.0.so)
  • app-emulation/emul-linux-x86-xlibs
  • app-emulation/emul-linux-x86-gtklibs

Arch

The required libs can be pulled from pacman before running.

If using Gnome, or KDE with some Gnome applications, the following will most likely be installed already:

  • gtk2
  • libgl
  • sdl
  • sdl_image

In addition, libtiff (<= 4, to be exact) is also required. Libtiff 4 is not available on Arch. Linking or copying /usr/lib/libtiff.so.3.8.2 to /usr/lib/libtiff.so.4 is sufficient.

The Dwarf Fortress files can be installed with an AUR frontend, or from the AUR itself if so inclined. The current files are at this page.

At a command prompt: 

 wget http://aur.archlinux.org/packages/dwarffortress/dwarffortress.tar.gz
 tar xvzf dwarffortress.tar.gz
 cd dwarffortress
 makepkg -s
 su
 pacman -U dwarffortress-v0.28.181.40d11-5-i686.pkg.tar.gz

OS X

A port of Dwarf Fortress to Mac OS X has been completed, and runs on both Intel and PPC based macs. According to the Website it requires system 10.3 or later, 100mb of hard drive space, and a minimum of 512mb of ram.
