ironwail

Ironwail a fork of the popular GLQuake descendant QuakeSpasm with a focus on high performance

instead of maximum compatibility, with a few extra features sprinkled on top.. By moving work from

the CPU to the GPU (culling, lightmap updates) and taking advantage of more modern OpenGL features

(instancing, compute shaders, persistent buffer mapping, indirect multi-draw, bindless textures),

this fork is capable of handling even the most demanding maps at very high framerates.

Features:

Supports Windows, Linux, other unices.

Well tested on both 32 bit and 64 bit platforms.

Well tested on both little endian and big endian platforms.

OpenGL improvements. In-game resolution changing.

Widescreen FOV (field of view) support and automatic Hor+ FOV scaling.

Improved sound support. Support for OGG, MP3, Opus and WAV external music files.

Improved game controller support using SDL2.

Countless bug fixes, security fixes and other improvements.

Support for playing the 'Quake 2021 re-release' content

Ironwail requires a copy of the Quake game data (Steam, GOG or Quake original CD), at the least in the

form of the shareware data file pak0.pak. In order to set this up, open (and if necessary create) the directory

~/.ironwail on your computer and copy the id1 directory from a copy of Quake original CD

there. For more info visit: https://github.com/andrei-drexler/ironwail.
