Video Games And Linux

Linux-based operating systems can be used for playing video games. Because few games natively support the Linux kernel, various software has been made to run Windows games, software, and programs, such as Wine, Cedega, DXVK, and Proton, and managers such as Lutris and PlayOnLinux. The Linux gaming community has a presence on the internet with users who attempt to run games that are not officially supported on Linux.

History

Linux gaming started largely as an extension of the already present Unix gaming scene, which dates back to that system's conception in 1969 with the game '' Space Travel'' and the first edition in 1971, with both systems sharing many similar titles. These games were mostly either arcade and parlour type games or text adventures using libraries like curses. A notable example of this are the "BSD Games", a collection of interactive fiction and other text-mode amusements. The free software philosophy and open-source methodology which drove the development of the operating system in general also spawned the creation of various early free games.

Popular early titles included ''Netrek'' and the various '' XAsteroids'', ''XBattle'', ''XBill'', '' XBoing'', ''X-Bomber'', ''XConq'', '' XDigger'', '' XEmeraldia'', ''XEvil'', '' XGalaga'', '' XGammon'', '' XLander'', '' XLife'', '' XMahjong'', '' XMine'', ''XSoldier'', ''XPilot'', '' XRobots'', '' XRubiks'', '' XShogi'', '' XScavenger'', '' XTris'', '' XTron'', '' XTic'' and ''XTux'' games using the X Window System. Other games targeted or also supported the SVGAlib library allowing them to run without a windowing system, such as ''LinCity'', ''Maelstrom'', ''Sasteroids'', and ''SABRE''. The General Graphics Interface was also utilized for games like ''U.R.B.A.N The Cyborg Project'' and '' Dave Gnukem'' ported from MS-DOS. As the operating system itself grew and expanded, the amount of free and open-source games also increased in scale and complexity, with both clones of historically popular releases beginning with ''BZFlag'', ''LinCity'', and ''FreeCiv'', as well as original creations such as ''Rocks'n'Diamonds'', ''Cube'', ''The Battle for Wesnoth'', and ''Tux Racer''.

1994

The beginning of Linux as a gaming platform for commercial video games is widely credited to have begun in 1994 when Dave D. Taylor ported the game ''Doom'' to Linux, as well as many other systems, during his spare time. Shareware copies of the game were included on various Linux discs, including those packed in with reference books.

''Ancient Domains of Mystery'' was also released for Linux in 1994 by Thomas Biskup, building on the roguelike legacy of games such as ''Moria'' and its descendent ''Angband'', but more specifically ''Hack'' and ''NetHack''.

1995

From there Taylor would also help found the development studio Crack dot Com, which released the video game ''Abuse'', with the game's Linux port even being distributed by Linux vendors Red Hat and Caldera. The studio's never finished ''Golgotha'' was also slated to be released by Red Hat in box.

In 1991 DUX Software contracted Don Hopkins to port ''SimCity'' to Unix, which he ported to Linux in 1995 and eventually released as open source for the OLPC XO Laptop.

A website called The Linux Game Tome, also known as HappyPenguin after its URL, was begun by Tessa Lau in 1995 to catalogue games created for or ported to Linux from the SunSITE game directories as well as other classic X11 games for a collection of just over 100 titles.

1996–1997

id Software, the original developers of ''Doom'', also continued to release their products for Linux. Their game '' Quake'' was ported to Linux via X11 in 1996, once again by Dave D. Taylor working in his free time. An SVGALib version was also later produced by Greg Alexander in 1997 using recently leaked source code, but was later mainlined by id. Later id products continued to be ported by Zoid Kirsch and Timothee Besset, a practice that continued until the studio's acquisition by ZeniMax Media in 2009. Initially, Zoid Kirsch was responsible for maintaining the Linux version of Quake and porting QuakeWorld to Linux.

'' Inner Worlds'' was released for and developed on Linux. ''The UNIX Book of Games'', a 1996 publication by Janice Winsor, described various games with an accompanying CD-ROM containing executables and source code for Linux and SCO Unix.

1998

The Linux Game Tome was taken over by Bob Zimbinski in 1998 eventually growing to over 2000 entries, sponsored by retailer Penguin Computing and later LGP until it went down in 2013, although mirrors still exist.

The site LinuxGames covered news and commentary from November 1998 until its host Atomicgamer went down in 2015. It was established by Marvin Malkowski, head of the Telefragged gaming network, alongside Al Koskelin and Dustin Reyes; Reyes passed away August 8, 2023.

Zoid Kirsch from id Software ported Quake II to Linux. Two programmers from Origin ported ''Ultima Online'' to Linux and MP Entertainment released an adventure game ''Hopkins FBI'' for Linux

On November 9, 1998, a new software firm called Loki Software was founded by Scott Draeker, a former lawyer who became interested in porting games to Linux after being introduced to the system through his work as a software licensing attorney. Loki, although a commercial failure, is credited with the birth of the modern Linux game industry. Loki developed several free software tools, such as the Loki installer (also known as Loki Setup), and supported the development of the Simple DirectMedia Layer, as well as starting the OpenAL audio library project. These are still often credited as being the cornerstones of Linux game development. They were also responsible for bringing nineteen high-profile games to the platform before its closure in 2002.

1999

Loki published '' Civilization: Call to Power'', ''Eric's Ultimate Solitaire'', Heretic II, Heroes of Might and Magic III, Railroad Tycoon II: Gold Edition, Quake III: Arena, and Unreal Tournament for Linux.

Loki's initial success also attracted other firms to invest in the Linux gaming market, such as Tribsoft, Hyperion Entertainment, Macmillan Digital Publishing USA, Titan Computer, Xatrix Entertainment, Philos Laboratories, and Vicarious Visions.

The ports of ''Quake'' and ''Quake II'' were released physically by Macmillan Computer Publishing USA, while ''Quake III'' was released for Linux by Loki Software. Red Hat had previously passed on publishing ''Quake'' for Linux, since it was not open-source at the time.

Philos Laboratories released a Linux version of ''Theocracy'' on the retail disk. Ryan "Ridah" Feltrin from Xatrix Entertainment released a Linux version of '' Kingpin: Life of Crime''.

BlackHoleSun Software released ''Krilo'' and Futureware 2001 released a trading simulation Würstelstand for Linux.

The Indrema Entertainment System (also known as the L600) was also in development since 1999 as a Linux based game console and digital media player, but production halted in 2001 due to a lack of investment, although the TuxBox project attempted a continuation.

2000

Loki published Descent 3, Heavy Gear II, SimCity 3000, and Soldier of Fortune for Linux. They also released the expansion Descent 3: Mercenary as the downloadable Linux installer.

Hyperion Entertainment ported Sin to Linux published by Titan Computer. Vicarious Visions ported the space-flight game ''Terminus'' to Linux. Mountain King Studios released a port of '' Raptor: Call of the Shadows'' and CipSoft published the Linux client of Tibia.

Boutell.com ported '' Exile III: Ruined World'' to Linux, which was a game created by Spiderweb Software.

During this time Michael Simms founded Tux Games, one of the first online Linux game retailers, later followed by Fun 4 Tux, Wupra, ixsoft, and LinuxPusher.

The period also saw a number of commercial compilations released, such as ''100 Great Linux Games'' by Global Star Software, ''Linux Games'' by Walnut Creek CDROM, ''Linux Games++'' by Pacific Hitech, ''Linux Cubed Series 8 LINUX Games'' by Omeron Systems, ''Best Linux Games'' by SOT Finnish Software Engineering, ''LinuxCenter Games Collection'', ''Linux Games & Entertainment for X Windows'' by Hemming, ''Linux Spiele & Games'' by more software, ''Linux Spiele'' by Franzis Verlag, and ''play it! Linux: Die Spielesammlung'' by S.A.D. Software.

Numerous Linux distributions and collections packed in Loki games and demos, including Red Hat Linux, Corel Linux and WordPerfect Office, and the complete ''Eric's Ultimate Solitaire'' bundled with PowerPlant by TheKompany. Easy Linux 2000 similarly bundled in a copy of the Linux version of ''Hopkins FBI''.

2001

Loki published Heavy Metal: F.A.K.K.², Kohan: Immortal Sovereigns, MindRover: The Europa Project, Myth II: Soulblighter, Postal Plus, Rune, Rune: Halls of Valhalla, Sid Meier's Alpha Centauri, and Tribes 2 for Linux.

Linux Game Publishing was founded in 2001 in response to the impending demise of Loki. Creature Labs ported '' Creatures: Internet Edition'' to Linux, which was published by LGP.

Hyperion Entertainment ported Shogo: Mobile Armor Division to Linux, and Tribsoft created a Linux version of Jagged Alliance 2, both published by Titan Computer.

Illwinter Game Design released Conquest of Elysium II and Dominions: Priests, Prophets & Pretenders for Linux. Introversion Software released Uplink for Linux.

BlackHoleSun Software released ''Bunnies'', and worked on ''Atlantis: The Underwater City - Interactive Storybook'' published by Sterling Entertainment.

GLAMUS GmbH released a Linux version of their game ''Mobility'' and Oliver Hamann released the driving game ''Odyssey by Car''.

Small Rockets published Small Rockets BackGammon, Small Rockets Mah Jongg, and Small Rockets Poker for Linux.

The company TransGaming marketed as a monthly subscription its own proprietary fork of Wine called WineX in October 2001, later renamed Cedega in 2004 and discontinued in 2011, which aimed for greater compatibility with Microsoft Windows games.
A special Gaming Edition of Mandrake Linux 8.1 was released that featured WineX packed in with ''The Sims''. The fact that the fork of Wine did not release source back to the main project was also a point of contention, despite promises to release code after achieving a set number of subscribers.

The release of ScummVM in 2001, Dosbox in 2002, as well as video game console emulators like MAME from 1997 and released as open source in 2016, helped make Linux a viable platform for retro gaming (facilitated by the RetroArch frontend since 2010). This is especially the case for the GP2X series of handheld game consoles by GamePark Holdings in addition to the community driven Pandora and DragonBox Pyra. Dedicated emulation setups are also built on single-board computers like the Raspberry Pi released in 2012, which are most often Linux based including with Raspberry Pi OS. Wine is also useful for running older Windows games, including 16-bit and even some 32-bit applications that no longer work on modern 64-bit Windows. The Sharp Zaurus personal data assistants adopted a Linux derived system called OpenZaurus, which attracted its own gaming scene. This was also the case with the Agenda VR3, advertised as the first "pure Linux PDA".

2002

After Loki's closure, the Linux game market experienced some changes. Although some new firms, such as Linux Game Publishing and RuneSoft, would largely continue the role of a standard porting house, the focus began to change with Linux game proponents encouraging game developers to port their game products themselves or through individual contractors. Influential to this was Ryan C. Gordon, a former Loki employee who would over the next decade port several game titles to multiple platforms, including Linux.

Ryan ported America's Army, Candy Cruncher, Serious Sam: The First Encounter, and Unreal Tournament 2003 to Linux.

Linux Game Publishing had initially tried to pick up the support rights to many of Loki's titles, but in the end it was only able to acquire the rights to MindRover: The Europa Project. They released the updated version of Mindrover and its downloadable update for owners of the old Loki version.

Return to Castle Wolfenstein was released for Linux and with the Linux port done in-house by Timothee Besset

Chronic logic released Bridge Construction Set and Triptych for Linux.

Sunspire Studios released in retail commercial expansion of the game titled ''Tux Racer''.

2003

Ryan ported Devastation, Medal of Honor Allied Assault, and Serious Sam: The Second Encounter to
Linux.

LGP took interest in publishing Pyrogon games on physical CDs and they released Candy Cruncher. Mathieu Pinard from Tribsoft got LGP in contact with Cyberlore to save the Linux port of Majesty because Titan Computer get out of Linux publishing. This turn of events helped LGP to release a Majesty for Linux after Pinard closed his company in 2002.

Timothee Bessett from id Software ported Wolfenstein: Enemy Territory to Linux.

Around this time many companies, starting with id Software, also began to release legacy source code leading to a proliferation of source ports of older games to Linux and other systems. This also helped expand the already existing free and open-source gaming scene, especially with regards to the creation of free first person shooters. In addition, numerous game engine recreations have been produced to varying levels of accuracy using reverse engineering or underlying engine code supporting the original game files including on Linux and other niche systems.

2004

Ryan ported Unreal Tournament 2004 to Linux for Epic Games and Timothee Bessett from id Software ported Doom 3 to Linux.

David Hedbor, founder and main programmer of Eon Games ported '' NingPo MahJong'' and '' Hyperspace Delivery Boy!'' to Linux, which later were published by LGP.

2005–2007

Ryan ported Postal²: Share The Pain to Linux published by LGP.

CodeWeavers offered an enhanced version of Wine called CrossOver Games. The reliance on such compatibility layers remains controversial with concerns that it hinders growth in native development, although this approach was defended based on Loki's demise. PlayOnLinux, established in 2007, provides a community alternative, with various guides being written on how to get games to run through Wine.

2008–2011

The Linux gaming market also started to experience some growth towards the end of the decade with the rise of independent video game development, with many "indie" developers favouring support for multiple platforms. The Humble Indie Bundle initiatives inaugurated in 2010 helped to formally demonstrate this trend, with Linux users representing a sizable population of their purchase base, as well as consistently being the most financially generous in terms of actual money spent. The Humble Indie Bundle V in 2012 faced controversy for featuring a Wine-based release of ''Limbo'' prepared by CodeWeavers, while a native version was later released in 2014. Humble eventually began offering Windows-only games in their bundles and on their store.

In 2009, the small indie game company Entourev LLC published ''Voltley'' to Linux which is the first commercial exclusive game for this operating system. In the same year, LGP released '' Shadowgrounds'' which was the first commercial game for Linux using the Nvidia PhysX middleware. The GamingOnLinux website was launched on July 4, 2009, and eventually succeeded LinuxGames as the main source of news and commentary.

The release of a Linux version of Desura in 2011, a digital distribution platform with a primary focus on small independent developers, was heralded by several commentators as an important step to greater acknowledgement of Linux as a gaming platform. Shortly before this, Canonical launched the Ubuntu Software Center which also sold digital games. The digital store Gameolith also launched in 2011 focused principally on Linux before expanding in 2012 and closing in 2014.

2012–2016

In July 2012, game developer and content distributor Valve announced a port of their Source engine for Linux as well as stating their intention to release their Steam digital distribution service for Linux. The potential availability of a Linux Steam client had already attracted other developers to consider porting their titles to Linux, including previously Mac OS only porting houses such as Aspyr Media and Feral Interactive.

In November 2012, Unity Technologies ported their Unity engine and game creation system to Linux starting with version 4. All of the games created with the Unity engine can now be ported to Linux easily.

In September 2013 Valve announced that they were releasing a gaming oriented Linux based operating system called SteamOS with Valve saying they had "come to the conclusion that the environment best suited to delivering value to customers is an operating system built around Steam itself." This was used for their Steam Machine platform released on November 10, 2015, and discontinued in 2018.

In March 2014 GOG.com announced they would begin to support Linux titles on their DRM free store starting the same year, after previously stating they would not be able due to too many distributions. GOG.com began their initial roll out on July 24, 2014, by offering 50 Linux supporting titles, including several new to the platform.

Despite previous statements, GOG have confirmed they have no plans to port their Galaxy client to Linux. The free software Lutris started in 2010, GameHub from 2019, MiniGalaxy from 2020, and the Heroic Games Launcher from 2021, offer support for GOG as well as the Epic Games Store, Ubisoft Connect and Origin.

In March and April 2014 two major developers Epic Games and Crytek announced Linux support for their next generation engines Unreal Engine 4 and CryEngine respectively.

Towards the end of 2014 the game host itch.io announced that Linux would be supported with their developing open source game client. This was fully launched simultaneously on Windows, Mac OS X and Linux on December 15, 2015. The service had supported Linux since it was first unveiled on March 3, 2013, with creator Leaf Corcoran personally a Linux user. The similar Game Jolt service also supports Linux and has an open source client released on January 13, 2016. GamersGate also sells games for Linux.

2017–present

On August 22, 2018, Valve released their fork of Wine called Proton, aimed at gaming. It features some improvements over the vanilla Wine such as Vulkan-based DirectX 11 implementation, Steam integration, better full screen and game controller support and improved performance for multi-threaded games. It has since grown to include support for DirectX 9 and DirectX 12 over Vulkan. The itch.io app added its own Wine integration in June 2020, while Lutris and PlayOnLinux are long-standing independent solutions for compatibility wrappers.

As with Wine and Cedega in the past, concerns have been raised over whether Proton hinders native development more than it encourages use of the platform. '' Prodeus'' dropped native support in favour of Proton shortly before final release and Arcen Games cancelled planned native support for ''Heart of the Machine''. Valve has expressed no preference over Proton or native ports among developers.

On February 25, 2022, Valve released Steam Deck, a handheld game console running SteamOS 3.0. The deployment of Proton and other design decisions were based on the limited response to their previous Steam Machines. Linux was also used as a base for several nostalgia consoles, including the Neo Geo X, NES Classic Edition, Super NES Classic Edition, Sega Genesis Mini, Intellivision Amico, Lichee Pocket 4A, and the Atari VCS. It also powers the more general Polymega, Anbernic RG351 and 5G552, as well as the Game Gadget, Evercade, VS, EXP and Super Pocket retrogaming consoles by Blaze Entertainment.

As of early 2023, the retro game store Zoom Platform was enhancing Linux support on their available titles.

Commercial games for non-x86 instruction sets

Some companies ported games to Linux running on instruction sets other than x86, such as Alpha, PowerPC, Sparc, MIPS or ARM.

Loki Entertainment Software ported '' Civilization: Call to Power'', ''Eric's Ultimate Solitaire'', ''Heroes of Might and Magic III'', '' Myth II: Soulblighter'', ''Railroad Tycoon II Gold Edition'' and ''Sid Meier's Alpha Centauri'' with ''Alien Crossfire'' expansion pack to Linux PowerPC. They also ported ''Civilization: Call to Power'', ''Eric's Ultimate Solitaire'', ''Sid Meier's Alpha Centauri'' with ''Alien Crossfire'' expansion pack to Linux Alpha and ''Civilization: Call to Power,'' ''Eric's Ultimate Solitaire'' to Linux SPARC.

Linux Game Publishing published '' Candy Cruncher'', ''Majesty Gold'', '' NingPo MahJong'' and '' Soul Ride'' to Linux PowerPC. They also ported ''Candy Cruncher'', ''Soul Ride'' to Linux SPARC and ''Soul Ride'' to Linux Alpha.

Illwinter Game Design ported '' Dominions: Priests, Prophets and Pretenders'', '' Dominions II: The Ascension Wars'' and ''Dominions 3'' to Linux PowerPC, as well as '' Conquest of Elysium 3'', '' Dominions 4: Thrones of Ascension'' to Raspberry Pi.

Hyperion Entertainment ported ''Sin'' to Linux PowerPC published by Titan Computer and ''Gorky 17'' to Linux PowerPC which later was published by LGP.

Runesoft hired Gunnar von Boehn which ported ''Robin Hood – The Legend of Sherwood'' to Linux PowerPC. Later Runesoft ported ''Airline Tycoon Deluxe'' to Raspberry Pi was running Debian GNU/Linux.

Iain McLeod ported Spheres of Chaos to Linux on the PlayStation 2 consoles and later re-released it as a freeware game.

Market share

The Steam Hardware Survey reports that as of January 2024, 2% of users are using some form of Linux as their platform's primary operating system. The Unity game engine used to make their statistics available and in March 2016 reported that Linux users accounted for 0.4% of players. In 2010, in the first Humble Bundle sales, Linux accounted for 18% of purchases.

Supported hardware

Linux as a gaming platform can also refer to operating systems based on the Linux kernel and specifically designed for the ''sole purpose'' of gaming. Examples are SteamOS, which is an operating system for Steam Machines, Steam Deck and general computers, video game consoles built from components found in the classical home computer, (embedded) operating systems like Tizen and Pandora, and handheld game consoles like GP2X, and Neo Geo X. The Nvidia Shield runs Android as an operating system, which is based on a modified Linux kernel.

The open source design of the Linux software platform allows the operating system to be compatible with various computer instruction sets and many peripherals, such as game controllers and head-mounted displays. As an example, HTC Vive, which is a virtual reality head-mounted display, supports the Linux gaming platform.

Performance

In 2013, tests by Phoronix showed real-world performance of games on Linux with proprietary Nvidia and AMD drivers were mostly comparable to results on Windows 8.1. Phoronix found similar results in 2015, though Ars Technica described a 20% performance drop with Linux drivers.

Software architecture

An operating system based on the Linux kernel and customized specifically for gaming, could adopt the vanilla Linux kernel with only little changes, or—like the Android operating system—be based on a relative extensively modified Linux kernel. It could adopt GNU C Library or Bionic or something like it. The entire middleware or parts of it, could very well be closed-source and proprietary software; the same is true for the video games. There are free and open-source video games available for the Linux operating system, as well as proprietary ones.

Linux kernel

The subsystems already mainlined and available in the Linux kernel are most probably performant enough so to not impede the gaming experience in any way, however additional software is available, such as e.g. the Brain Fuck Scheduler (a process scheduler) or the Budget Fair Queueing (BFQ) scheduler (an I/O scheduler).

Similar to the way the Linux kernel can be, for example, adapted to run better on supercomputers, there are adaptations targeted at improving the performance of games. A project concerning itself with this issue is called Liquorix.

Available software for video game designers

Game creation systems

Several game creation systems can be run on Linux, such as Game Editor, GDevelop, Construct and Stencyl, as well as beta versions of GameMaker. A Linux version of Clickteam Fusion 3 was mentioned, but has yet to be released. The Godot, Defold, and Solar2D game engines also supports creating games on Linux, as do the commercial UnrealEd and Unity Editor, The visual programming environments Snap!, Scratch 1.X and Tynker are Linux compatible. Enterbrain's RPG Maker MV was released for Linux. In addition, open-source, cross-platform clones of the RPG Maker series exist such as Open RPG Maker, MKXP and EasyRPG, as well as the similar Official Hamster Republic Role Playing Game Construction Engine, OHRRPGCE and Solarus. The Adventure Game Studio editor is not yet ported to Linux, although games made in it are compatible, and the Wintermute Engine, Wintermute and SLUDGE adventure game engines are available. ZGameEditor, Novashell, GB Studio, and the ZZT inspired MegaZeux are also options. Versions of Mugen (game engine), Mugen were made available for Linux, and open-source re-implementations such as IKEMEN Go are compatible. The JavaScript based Ct.js Pixelbox.js, and Superpowers (software), Superpowers
are also options.

Level editors

Various level editors exists for Linux, such as Qoole, wxqoole, GtkRadiant, TrenchBroom and J.A.C.K. for the id Tech engines and related, Eureka, SLADE and ReDoomEd for the Doom engine, ''Doom'' engine, and the general purpose tile map editors LDtk, Ogmo, and Tiled.

Debuggers

Several game development tools have been available for Linux, including GNU Debugger, LLDB (debugger), LLDB, Valgrind, glslang and others. VOGL, a debugger for OpenGL was released on 12 March 2014.

Available interfaces and SDKs

There are multiple Application programming interface, interfaces and Software Development Kits available for Linux, and almost all of them are cross-platform. Most are free and open-source software subject to the terms of the zlib License, making it possible to static link against them from fully closed-source proprietary software. One difficulty due to this abundance of interfaces, is the difficulty for programmers to choose the best suitable audio API for their purpose. The main developer of the PulseAudio project, Lennart Poettering, commented on this issue.
Physics engines, audio libraries, that are available as modules for game engines, have been available for Linux for a long time.

The book ''Programming Linux Games'' covers a couple of the available APIs suited for video game development for Linux, while ''The Linux Programming Interface'' covers the Linux kernel interfaces in much greater detail.

Available middleware

Beside majority of the software which acts as an interface to various subsystems of the operating system, there is also software which can be simply described as middleware. A multitude of companies exist worldwide, whose main or only product is software that is meant to be licensed and integrated into a game engine. Their primary target is the video game industry, but the film industry also utilizes such software for special effects. Some very few well known examples are
* classical physics: Havok (software), Havok, Newton Game Dynamics and PhysX
* audio: Audiokinetic Wwise, FMOD
* other: SpeedTree
A significant share of the available middleware already runs natively on Linux, only a very few run exclusively on Linux.

Available IDEs and source code editors

Numerous source code editors and Integrated development environment, IDEs are available for Linux, among which are Visual Studio Code, Sublime Text, Code::Blocks, Qt Creator, Emacs, or Vim (text editor), Vim.

Multi-monitor

A multi-monitor setup is supported on Linux at least by AMD Eyefinity & AMD Catalyst, Xinerama and RandR on both X11 and Wayland. ''Serious Sam 3: BFE'' is one example of a game that runs natively on Linux and supports very high resolutions and is validated by AMD to support their Eyefinity. ''Civilization V'' is another example, it even runs on a List of AMD Accelerated Processing Unit microprocessors#"Kaveri" (2014, 28 nm), "Kaveri" desktop APU in 3x1 portrait mode.

Voice over IP

The specifications of the Mumble (software), Mumble protocol are freely available and there are BSD-licensed implementations for both servers and clients. The positional audio API of Mumble is supported by e.g. ''Cube 2: Sauerbraten''.

Wine

Wine is a compatibility layer that provides binary compatibility and makes it possible to run software, that was written and compiled for Microsoft Windows, on Linux. The Wine project hosts a user-submitted application database (known as Wine AppDB) that lists programs and games along with ratings and reviews which detail how well they run with Wine. Wine AppDB also has a commenting system, which often includes instructions on how to modify a system to run a certain game which cannot run on a normal or default configuration. Many games are rated as running flawlessly, and there are also many other games that can be run with varying degrees of success. The use of Wine for gaming has proved controversial in the Linux community as some feel it is preventing, or at least hindering, the further growth of native gaming on the platform.

Emulators

There are numerous video game console emulator, emulators for Linux. There are also APIs, virtual machines, and machine emulators that provide binary compatibility:

* Anbox and Waydroid for the Android (operating system), Android operating system;
* Basilisk II for the Motorola 68040, 68040 Mac (computer), Mac;
* DOSBox and DOSEMU for MS-DOS and compatibles;
* DeSmuME and melonDS for the Nintendo DS;
* Dolphin (emulator), Dolphin for the GameCube, Wii, and the Triforce (arcade system board), Triforce;

* Fuse (emulator), Fuse for the Sinclair ZX Spectrum;
* Hatari (emulator), Hatari for the Atari ST, Atari STe, STe, Atari TT, TT and Atari Falcon, Falcon;
* gnuboy for the Nintendo Game Boy and Game Boy Color;
* MAME for arcade games (and previously Multi Emulator Super System, MESS for multiple hardware platforms);
* Mednafen and Xe emulating multiple hardware platforms including some of the above;
* Mupen64Plus and the no longer actively developed original Mupen64 for the Nintendo 64;
* PCSX-Reloaded, pSX and the Linux port of ePSXe for the PlayStation;

* VisualBoyAdvance, mGBA and Boycott Advance for the Game Boy Advance;
* Mini vMac and the no longer actively developed original vMac for the 680x0 Macintosh;

Linux homebrew on consoles

Linux has been ported to several game consoles, including the Xbox Linux, Xbox, Linux for PlayStation 2, PlayStation 2, PlayStation 3, PlayStation 4, GameCube, and Wii which allows game developers without an expensive game development kit to access console hardware. Several gaming peripherals also work with Linux.

Types of Linux gaming

Linux gaming can be divided into a number of sub-categories.

Libre gaming

Open-source video game, Libre gaming is a form of Linux gaming that emphasizes Free software, libre software, which often includes levels and assets as well as code.

Native gaming

Native gaming is a form of Linux gaming that emphasizes using only native games or ports and not using emulators or compatibility layers.

DRM-free gaming

Digital rights management#Opposition, DRM-free gaming is a form of Linux gaming that emphasizes boycotting DRM technologies. This can include buying games from GOG.com, certain Humble Bundles or itch.io and avoiding Steam and similar services.

Terminal gaming

Terminal gaming is the playing of text-based games from within a Command-line interface, console, often programmed within Bash (Unix shell), Bash or using libraries such as ncurses.

Retro gaming

Retrogaming is the playing of older games using emulators such as MAME or Dosbox, compatibility layers such as Wine and Proton, Game engine recreation, engine reimplementations and source ports, or even older Linux distributions (including live CDs and live USB, or virtual machines), original binaries,
and period hardware.

Live gaming

A number of games can be played from live CD, live distributions such as Knoppix, allowing easy access for users unwilling to fully commit to Linux. Certain live distros have specially targeted gamers, such as SuperGamer and Linux-Gamers.

Browser gaming

Browser gaming is the act of playing online games through a web browser, which has the advantage of largely being platform independent. The same largely applies to social network games hosted on social media sites. Older games were largely based on Adobe Flash, while modern ones are mostly HTML5.

Cloud gaming

Cloud gaming is the streaming of games from a central server onto a desktop client. This is another way to play games on Linux that are not natively supported, although some cloud services, such as the erstwhile Google Stadia, are hosted on Linux and Android servers. GamingAnywhere is an open source implementation.

On Windows

Although less exploited than the reverse, as few programs are Linux exclusive, support does exist for running Linux binaries from Windows. The Windows Subsystem for Linux allows the running of both command line and graphical Linux applications from Windows 10 and Windows 11. An earlier implementation is Cygwin, started by Cygnus Solutions and later maintained by Red Hat, although it has limited hardware access and required adaptation. The use of Wine can even allow for the running of Windows games on Linux from Windows. The LibTAS library for tool assisted speedruns currently recommends WSL to run on Windows. Naughty Dog meanwhile have used Cygwin to run old command-line tools for use in their game development, which is a broader use for the platform. As with running Windows applications on Linux, there is controversy over whether running Linux applications on Windows will dilute interest in Linux as distinct platform, though it has speciality uses.

Android gaming

Originally derived from Linux, the Android (operating system), Android mobile operating system has a distinct and popular gaming ecosystem. It has also been used as the base for several game consoles, such as the Nvidia Shield Portable and the Ouya. Popular games include ''Pokemon Go'', ''Genshin Impact'', ''League of Legends: Wild Rift'', ''Dead Cells'' and ''Call of Duty: Mobile''. Certain games, such as ''Minecraft'', ''Stardew Valley'', and ''Papers Please'', are available for both Android and desktop Linux.

ChromeOS gaming

ChromeOS is another Linux derived operating system by Google for its Chromebooks, and it too has a dedicated gaming ecosystem. Partly owing to a lack of high end graphics hardware, it is especially oriented towards cloud gaming via services like GeForce Now and Xbox Cloud Gaming, with models featuring Nvidia GPUs ultimately being cancelled. Numerous games for Android (operating system), Android have also been made compatible with ChromeOS, as well as a standard Linux games, Windows games via Wine or Proton, and with browser games also being popular. A version of Steam (software), Steam has been in development for ChromeOS, with third party launchers also available such as the Heroic Games Launcher for the Epic Games Store. Popular titles include ''Among Us'', ''Genshin Impact'', ''Alto's Odyssey'', ''Roblox'', and ''Fortnite''. Skepticism remains for using ChromeOS and Chromebooks as gaming machines.

BSD gaming

Owing to a common Unix-like heritage and free software ethos, many games for Linux are also ported to BSD List of BSD operating systems, variants or can be run using compatibility layers such as Linuxulator. BSDi had partnered with Loki Software to ensure its Linux ports ran on FreeBSD. The Mizutamari launcher exists to facilitate running Windows games through Wine, which can still be used standalone. A 2011 Benchmark (computing), benchmark by Phoronix even found certain speed advantages over running games on Linux itself, comparing PC-BSD 8.2 to Ubuntu (operating system), Ubuntu 11.04. Most BSD systems come with the same pack in desktop games as Linux. The Permissive license, permissive licensing of BSD has also lead to its inclusion in the system software of several game consoles, such as the Sony PlayStation line and the Nintendo Switch.

OpenHarmony gaming

HarmonyOS with custom kernel and OpenHarmony-Oniro based operating systems distros of these newer platforms has a dedicated gaming ecosystem with compatibilities with third-party Linux libraries by developers on Linux kernel subsystem such as Musl, musl-libc of C standard library, C standard library that targets the Linux syscall and POSIX APIs compatibility for native compatible games as well as limited virtual machines such as Android (operating system), Android-based sandboxed ones.

Unix gaming

A further niche exists for running games, either through ports or lxrun, on Solaris (operating system), Solaris and derivatives such as OpenIndiana, Darwin (operating system), Darwin distributions such as PureDarwin, Coherent (operating system), Coherent, SerenityOS, Redox OS, ToaruOS, Xv6, Fiwix, or on Minix and GNU Hurd, Hurd based systems. There has been some cross-pollination with purely proprietary Unix List of Unix systems, derivatives, such as AIX, QNX, Domain/OS, HP-UX, IRIX (:category:IRIX games, see here), Xenix, SCO Unix, Unixware, Tru64 UNIX, LynxOS (which features inbuilt Linux compatibility), Ultrix, OpenVMS, z/OS UNIX System Services, and even A/UX. The games ''Doom'' and '' Quake'' were developed by id Software on NeXTStep, a forerunner of modern macOS, before being ported to DOS and back to numerous other Unix variants. This involved reaching out to numerous Unix vendors to supply machines to use in the build and testing process.
