Yamagi Quake II

Yamagi Quake II is an alternative client for id Softwares Quake II. Our goal is to provide the best Quake II experience possible, we strive to preserve the game play as it was back in 1997. Thus we aim mostly for bug fixes, stability and gentle enhancements were appropriate.

Features

Yamagi Quake II has a lot of unique features. The most notables ones are:

• Modern OpenGL 3.2 and OpenGL ES 3.0 renderers, providing a greatly enhanced look and feel. The original OpenGL 1.4 and even the Software renderers are still supported. All 3D accelerated renderers support anisotropic filtering and multisampling anti aliasing.
• Full support for widescreen displays and arbitrary resolutions. The HUD can be scaled to be readable on HiDPI displays.
• Support for surround sound, from stereo up to 7.1 channels and even HRTF. The background music can be played from OGG/Vorbis files, a CD drive is no longer necessary.
• A rewritten savegame system. Yamagi Quake II savegames are completely reliable and backward compatible between releases.
• Highly precise timings. For example, on a flat panel display with a refresh rate of 144 hertz and vertical synchronisation (vsync) enabled Yamagi Quake II is running at exactly 144 frames per second. Without any physic bugs.
• In comparison with the original client over 2.000 bugs were fixed. The Yamagi Quake II client is very well tested and stable. The dedicated server is able to run for weeks without a single restart. Last but not least the code is fully 64 bit clean and highly portable.

Yamagi Quake II supports the following platforms:

• FreeBSD
• Linux
• OpenBSD
• Windows

Some additional platforms are supported by the community. Yamagi Quake II works on them, but there may be bugs. The Yamagi Quake II developers may not be able to fix these bugs due to the lack of required hardware or software:

• Haiku
• Mac OS
• NetBSD
• Solaris

News

On 2025-05-11 Yamagi Quake II version 8.51 was released. Changes are:

• Fix savegame and mod incompatibilities when Yamagi Quake II is complied in C23 mode. With this fix applied savegames written by unfixed binaries will crash the client. It is advised to complete the current run before upgrading. The official Windows binaries were not affected by this problem. Other platforms mostly if they build the binaries with GCC 15 which enables C23 mode by default.
• Fix memory leaks in the mod selection menu. (by David Carlier)
• General code cleanup around bool handling. (by 0lvin)

Contribution and Bugreports

The development of Yamagi Quake II is hosted on Github. If you want to report a bug or send some nice patches please open an issue or a pull request in the appropriate subproject. You can find our organization at: github.com/yquake2

If you’re planing to work on a bigger feature, please do yourself a favor and ask if we’re interested before spending time onto it. We don’t merge every feature that’s submitted to us just because the code is already there. Maintainability, integration with the existing code and our general focus are of great concern, too.
