{{Non-valve engine|game|Documentation on this wiki focuses on that which relates to Valve's engines. For links to external resources focused on Quake modding, see [[Quake/For developers]].}}
{{Quake|4}} is a 3D first-person shooter released in 1996 by [[Wikipedia: id Software|id Software]]. [[w:Quake engine|Its engine]] was licensed out to many companies, including [[Valve]]. {{gldsrc|3.1}} is based off of Quake engine code, specifically, GLQuake and Quakeworld (with some {{quake2|1}} code), with it's successors {{source|3.1}} and {{source2|3.1}} both still retaining some residual Quake code. 

The {{quakeengine|4}} introduced many of the concepts still used in Source today, such as the modern variant of the [[BSP]], the use of a [[PVS]], [[lightmap|precomputated lightmaps]], [[visleaf|visleafs]] and [[brush|brush entities]]. Early GoldSrc multiplayer was based off the QuakeWorld multiplayer code (until 2001, when some {{quake3|3.1}}{{cn}} code was added).

The {{quakeengine|3.1}} and its successor, the {{quake2engine|3.1}}, are now both retroactively referred to as {{idtech2|3.1}}. Both engines have been released as free and open source under the [[Wikipedia:GNU_General_Public_License#Version_2|GPLv2]] license, allowing for many [[#Source ports|source ports]] to be created, which add quality-of-life improvements and are now the preferred way of playing the game, including an [[W:Quake_(video_game)#Enhanced_version_and_Dimension_of_the_Machine|remaster released in 2021]].

==Compilers==
Quake also uses three compiler tools in compiling a map: [[QBSP (Quake)|QBSP]], [[VIS (Quake)|VIS]], and [[LIGHT (Quake compiler)|LIGHT]]. The code for these was used as the basis of the compiling tools used by the compilers used by the Valve engine map compilers, as seen below:

[[ericw-tools]] uses the same nomenclature as the original Quake compilers.

== Source ports ==
Since the release of the [https://github.com/id-Software/Quake Quake source code], there are various source ports available:
* [https://quakespasm.sourceforge.net/ Quakespasm] - Limit-breaking source port focused on vanilla accuracy. Fork of the long-deprecated FitzQuake. Actively maintained.
** [https://github.com/Shpoike/Quakespasm Quakespasm-Spiked (QSS)] - Fork of Quakespasm that can run at higher frame rates than 72FPS without breaking physics.
*** [https://github.com/Novum/vkQuake vkQuake] - Fork of QSS running on Vulkan, with additional features. No longer maintained as of 9 May 2023.
* [https://github.com/lipsanen/TASQuake TASQuake] - a port which allows to record inputs for tool assisted speedrunning (TAS) as [[.qtas]] files.
* {{fte}} [https://github.com/fte-team/fteqw FTEQW] - Source port focused on standalone game development. Notably includes [[Wikipedia:Clean room design|clean-room]] implementations of {{gldsrc|3.1}} file formats ([[BSP (GoldSrc)|BSP]], [[MDL (GoldSrc)|MDL]], [[WAD|WAD3]], [[SPR|HLSPR]]), being used for clean-room reverse-engineered ports of {{cs|2|addtext=&nbsp;1.5}} (as {{freecs|4.1}}) and {{hl|2|addtext=&nbsp;Deathmatch}} (as [[FreeHL]]). Actively maintained.

== Bugs/Limitations ==
{{Note|The original version (except Enhanced) of the game does not come with music due to various reasons:
- The GOG version originally ships the game soundtrack in {{Code|.ogg}} format. It was removed due to legal reasons.<br>
- The Steam version does not ship with the game soundtrack. However users can insert the original game disc in order to restore music playback.<br>
Alternatively, users can use third-party source port(s) and [https://steamcommunity.com/sharedfiles/filedetails/?id{{=}}119489135 download the soundtrack files] to restore the music.}}
{{Bug|hidetested=1|Overbright lighting (as found in the original software renderer) was broken on GLQuake with no options to re-enabling it via any command, which makes the color less saturated and lighting much darker.<br>{{gldsrc|4}} originally fixed this in its [[OpenGL]] renderer (disableable with {{command|gl_overbright|0}}, but it was broken again in an update that added multitexturing support, then later fixed again with [[Half-Life|HL]]'s 25th anniversary update. Details for this bug on GoldSrc can be found on [[GoldSrc|it's page about the engine itself]]. <br>Modern source ports fix this, via a {{command|gl_overbright}} command, like GoldSrc.
{{modernConfirm|Does this discrepancy exist in Quake 2? It's probably fixed in IdTech 3, as that has r_overbrightbits (which works a bit differently than Quake and GoldSrc).}} }}
{{bug|hidetested=1|Fullbright texels are broken in GLQuake{{elaborate}}.}}
