ZDoom LE, also known as ZDoom Legacy Edition, is a MiniWikipediaLogoIcon.pngfork of the ZDoom source port by drfrag. It is based off ZDoom 2.8.1, and in a separate fork, also includes a OpenGL renderer courtesy of GZDoom 1.8.4 with additional fixes. It focuses on updating the last ZDoom release with new features for older and legacy computers whilst maintaining compatibility with several mods, such as Brutal Doom.


ZDoom LE released in both software rendered and OpenGL based versions independently under the same 2.8.1 moniker. This changed with ZDoom LE 2.8.1d, which saw the OpenGL version gotten raised to 2.8.2a. Since then, both subversions retain similarity in terms of feature set, but deviate in terms of version numbers. As of this writing, the latest versions are:

  • Software rendering only: ZDoom LE 2.8.1f, released February 14, 2019
  • OpenGL rendering: ZDoom LE 2.8.3a, released February 14, 2019


  • All features from ZDoom 2.8.1 (ACS, etc) and GZDoom 1.8.4
  • Various patches and fixes for older mods
  • OpenGL 1.2 based renderer courtesy of GZDoom 1.8.4 (LE 2.8.x)
  • Restored MiniWikipediaLogoIcon.pngDirect3D renderer
  • Compiled with Pentium II architecture optimizations
  • Sprite and wall distance culling to improve performance
  • Low detail modes (2x2, 3x2, 4x4)
  • Quad horizontally and double vertically render modes
  • Modernized keyboard layout
  • FluidSynth midi support

System requirements

  • ZDoom LE requires the following: Pentium 133, 16 MB RAM, 1 MB MiniWikipediaLogoIcon.pngSVGA card and Windows 95. For OpenGL mode a graphics card with GL 1.2 support is required.
