__TOC__

== OS ==

* '''Windows''' requires XP SP3 or newer.
* '''Linux''' runs natively or using Wine.
* '''Mac''' needs Intel chip. (OS X Lion works, but requires [[v0.31:Installation#Mac|a short modification]] to run)

'''Note:''' ''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. Expect the process to allocate between 300 and 700 MB with medium regions. 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 less 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. <!-- Is this correct?  Longer worldgen history may increase RAM use during Fortress mode play, IIRC... or was that a bug? -->

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). It's also essential that you mention the state of your fortress - how many dwarves there are, animals, terrain, speedups, and so forth.

== SDL vs. Legacy ==
[http://www.libsdl.org/ SDL] is a cross-platform application framework. The SDL version of DF runs on Windows, Mac OS X, and Linux. It includes Baughn's new OpenGL code, which is faster and has more features (including support for PNG tilesets and using scroll wheels).

"Legacy" refers to the (Windows-only) framework Toady used before migrating to SDL. The legacy version is only necessary if the SDL version doesn't work for some reason.
