Software:Video games and Linux

From HandWiki
Short description: Playing video games on the Linux operating system


The operating system Linux can be used for playing video games. Because many games are not natively supported for the Linux kernel, various software has been made to run Windows games, such as Wine, Cedega, 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 normally not supported on Linux.

History

NetHack, a primordial Unix game


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.[1][2] 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,[3] as well as original creations such as Rocks'n'Diamonds and Tux Racer.[4]

1994–1997

Doom was one of the first major commercial games to be released for Linux.

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.[5][6] From there he 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 vendor Red Hat.[7][8] The studio's never finished Golgotha was also slated to be released by Red Hat in box.[9] 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.

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.[10][11] An SVGALib version was also later produced by Greg Alexander in 1997 using recently leaked source code, but was later mainlined by id.[12] Later id products continued to be ported by Zoid Kirsch[13] and Timothee Besset,[14] a practice that continued until the studio's acquisition by ZeniMax Media in 2009.[15] The ports of Quake and Quake II were released physically by Macmillan Computer Publishing USA,[16] while Quake III was released for Linux by Loki Software.[17]

In 1991 DUX Software contracted Don Hopkins to port SimCity to Unix,[18] which he later ported to Linux and eventually released as open source for the OLPC XO Laptop.[19] Other early commercial Linux games included Hopkins FBI, an adventure game released in 1998 by MP Entertainment,[20] and Inner Worlds in 1996, which was released for and developed on Linux.[21] In 1998, two programmers from Origin ported Ultima Online to Linux.[22] 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.[23]

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. It 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.[24][25]

1998–2002

The Simple DirectMedia Layer provided platform independent abstraction

The site LinuxGames covered news and commentary from November 1998 until its host Atomicgamer went down in 2015.[26][27]

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.[28] 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),[29] and supported the development of the Simple DirectMedia Layer, as well as starting the OpenAL audio library project.[30][31] These are still often credited as being the cornerstones of Linux game development.[32] They were also responsible for bringing nineteen high-profile games to the platform before its closure in 2002.

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. During this time Michael Simms founded Tux Games, one of the first online Linux game retailers,[33] later followed by Fun 4 Tux,[34] Wupra,[35] ixsoft, and LinuxPusher.[36]

The period also saw a number of commercial compilations released, such as 100 Great Linux Games by Global Star Software,[37] Linux Games by Walnut Creek CDROM,[38][39] Best Linux Games by SOT Finnish Software Engineering,[40][41][42] Linux Games & Entertainment for X Windows by Hemming,[43] Linux Spiele & Games by more software,[44] Linux Spiele by Franzis Verlag,[45] and play it! Linux: Die Spielesammlung by S.A.D. Software.[46]

The release of ScummVM in 2001,[47] Dosbox in 2002,[48] 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).[49][50] This is especially the case for dedicated emulation setups built on single-board computers like the Raspberry Pi released in 2012, which are most often Linux based including with Raspberry Pi OS.[51] Wine is also useful for running older Windows games,[52] including 16-bit and even some 32-bit applications that no longer work on modern 64-bit Windows.[53]

2003–2007

Former Loki Software employee Ryan C. Gordon

After Loki's closure, the Linux game market experienced some changes.[54] 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.[55] 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.[56]

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.[57] This also helped expand the already existing free and open-source gaming scene, especially with regards to the creation of free first person shooters.[58] 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.[59][60]

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. CodeWeavers also offered an enhanced version of Wine called CrossOver Games.[61][62] The reliance on such compatibility layers remains controversial with concerns that it hinders growth in native development,[63][64] although this approach was defended based on Loki's demise.[65][66] PlayOnLinux, established in 2007, provides a community implementation.[67]

2008–2011

Number of sales of the first Humble Indie Bundle across systems[68]

  Windows (61.9%)
  Mac (21.6%)
  Linux (16.5%)

Proportional values of payments[68]

  Windows (52.1%)
  Mac (23.0%)
  Linux (24.9%)

The Linux gaming market also started to experience some growth towards the end of the decade with the rise of independent video game development,[69] with many "indie" developers favouring support for multiple platforms.[70] The Humble Indie Bundle initiatives inaugurated in 2010 helped to formally demonstrate this trend,[71] 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.[72][73] The Humble Indie Bundle V in 2012 faced controversy for featuring a Wine-based release of Limbo prepared by CodeWeavers,[74] while a native version was later released in 2014.[75] Humble eventually began offering Windows-only games in their bundles and on their store.[76][77]

In 2009, the small indie game company Entourev LLC published Voltley to Linux which is the first commercial exclusive game for this operating system.[78][79] In the same year, LGP released Shadowgrounds which was the first commercial game for Linux using the Nvidia PhysX middleware.[80] The GamingOnLinux website was launched on July 4, 2009, and eventually succeeded LinuxGames as the main source of news and commentary.[81]

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.[69][82][83] Shortly before this, Canonical launched the Ubuntu Software Center which also sold digital games.[84] The digital store Gameolith also launched in 2011 focused principally on Linux before expanding in 2012 and closing in 2014.[85][86]

2012–2016

Lutris, an open source launcher for various distribution platforms

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.[87][88][89] The potential availability of a Linux Steam client had already attracted other developers to consider porting their titles to Linux,[83][90][91][92] including previously Mac OS only porting houses such as Aspyr Media and Feral Interactive.[93]

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.[94]

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."[83][95] This was used for their Steam Machine platform released on November 10, 2015, and discontinued in 2018.[96]

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.[97] GOG.com began their initial roll out on July 24, 2014, by offering 50 Linux supporting titles, including several new to the platform.[98]

Despite previous statements, GOG have confirmed they have no plans to port their Galaxy client to Linux.[99] The free software Lutris started in 2010,[100] GameHub from 2019,[101] MiniGalaxy from 2020,[102] and the Heroic Games Launcher from 2021,[103] 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.[104][105]

Towards the end 2014 the game host itch.io announced that Linux would be supported with their developing open source game client.[106] This was fully launched simultaneously on Windows, Mac OS X and Linux on December 15, 2015.[107] The service had supported Linux since it was first unveiled on March 3, 2013, with creator Leaf Corcoran personally a Linux user.[108] The similar Game Jolt service also supports Linux and has an open source client released on January 13, 2016.[109][110] GamersGate also sells games for Linux.[111][112]

2017-present

Steam Deck, a handheld game console running Linux-based operating system

On August 22, 2018, Valve released their fork of Wine called Proton, aimed at gaming.[113] 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.[114] It has since grown to include support for DirectX 9[115] and DirectX 12[116] over Vulkan. The itch.io app added its own Wine integration in June 2020,[117] while Lutris and PlayOnLinux are long-standing independent solutions for compatibility wrappers.[118][119]

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,[120][121] with Prodeus dropping native support in favour of Proton shortly before final release.[122] Valve has expressed no preference over Proton or native ports among developers.[123]

On February 25, 2022, Valve released Steam Deck, a handheld game console running SteamOS 3.0.[124][125] The deployment of Proton and other design decisions were based on the limited response to their previous Steam Machines.[126]

As of early 2023, the retro game store Zoom Platform was enhancing Linux support on their available titles.[127]

Market share

The Steam Hardware Survey reports that as of July 2021, 1% of users are using some form of Linux as their platform's primary operating system.[128] The Unity game engine used to[129] make their statistics available and in March 2016 reported that Linux users accounted for 0.4% of players.[130] In 2010, in the first Humble Bundle sales, Linux accounted for 18% of purchases.[131]

Supported hardware

The Pandora was a Linux integrated game console from 2010

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.[citation needed]

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.[citation needed]

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.[132] Phoronix found similar results in 2015,[133] though Ars Technica described a 20% performance drop with Linux drivers.[134]

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.[citation needed]

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,[citation needed] 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).[135]

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.[136][137]

Available software for video game designers

Debuggers

Several game development tools have been available for Linux, including GNU Debugger, LLDB, Valgrind, glslang and others. VOGL, a debugger for OpenGL was released on 12 March 2014. An open-source, cross-platform clone of Enterbrain's RPG Maker (2000, 2003, XP, VX), called OpenRPG Maker, is currently in development.[138]

Available interfaces and SDKs

There are multiple 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.[139] Physics engines, audio libraries, that are available as modules for game engines, have been available for Linux for a long time.[time needed][citation needed]

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

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 IDEs are available for Linux, among which are Visual Studio Code, Sublime Text, Code, Qt Creator, Emacs, or 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 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.[141] Civilization V is another example, it even runs on a "Kaveri" desktop APU in 3x1 portrait mode.[142]

Voice over IP

The specifications of the 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.

Wine

PlayOnLinux helps make Wine gaming accessible
Main page: Software: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.[143][144]

Emulators

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



Linux homebrew on consoles

Main page: Software:Homebrew (video games)

Linux has been ported to several game consoles, including the Xbox, PlayStation 2, PlayStation 3, PlayStation 4,[145] GameCube,[146] and Wii which allows game developers without an expensive game development kit to access console hardware. Several gaming peripherals also work with Linux.[147][148]

Linux adoption

Adoption by game engines

The game engine is important for players and developers alike. The development-kit is built around it, game editors use it to build levels. Tools such as Blender or 3ds Max are employed to create the geometry of object and/or animations of those. Game data has reached enormous amounts. While game engines are sometimes released under some free software license, instead or additionally to licensing them, the game data is usually not.

The game engine is the software solely responsible for the game mechanics, or rules defining game play. There are different game engines for first-person shooters, strategy video games, etc. Besides the game mechanics, software is also needed to handle graphics, audio, physics, input handling, and networking.

Game engines that are used by many video games and run on top of Linux include:

Adoption by video games

Main page: Software:List of Linux games

There are many free and open-source video games as well as commercially distributed proprietary video games that run natively on Linux. Some independent companies have also begun porting prominent video games from Microsoft Windows to Linux.

Source ports

Main page: Source port
Micropolis, an open source port of SimCity

Several developers have released the source code to many of their legacy titles, allowing them to be run as native applications on many alternative platforms, including Linux. Examples of games which were ported to Linux this way include Duke Nukem 3D, Shadow Warrior, Rise of the Triad, Blake Stone, Ken's Labyrinth, Catacomb 3D, Seven Kingdoms, Warzone 2100, Homeworld, Call to Power II, Wolfenstein 3D, Heretic, Hexen, Hexen II, Aliens versus Predator, Descent, Descent II and Freespace 2.[57] Several game titles that were previously released for Linux were also able to be expanded or updated because of the availability of game code, including Doom, Abuse, Quake, Quake II, Quake III Arena and Jagged Alliance 2. Some derivatives based on released source code have also been released for Linux, such as Aleph One and Micropolis for Marathon 2 and SimCity respectively.

Certain game titles were even able to be ported due to availability of shared engine code even though the game's code itself remains proprietary or otherwise unavailable, such as the video game Strife, Blood, PowerSlave, Redneck Rampage,[177] or the multiplayer component of Star Trek: Voyager – Elite Force.[178] Some games have even been ported entirely or partially by reverse engineering and game engine recreation such as WarCraft II through Wargus or Commander Keen through Commander Genius.[60] Another trick is to attempt hacking the game to work as a mod on another native title, such as with the original Unreal.[179] Additionally, some games can be run through the use of Linux specific runtime environments, such as the case of certain games made with Adventure Game Studio such as the Chzo Mythos[180] or certain titles made with the RPG Maker tool. Games derived from released code, with both free and proprietary media, that are released for Linux include Urban Terror, OpenArena, Freedoom, World of Padman, Nexuiz/Xonotic, War§ow, The Dark Mod, and Excalibur.[181]

Types of Linux gaming

Linux gaming can be divided into a number of sub-categories.[182][183][184]

Libre gaming

Libre gaming is a form of Linux gaming that emphasizes libre software, which often includes levels and assets as well as code.[185][self-published source?][186]

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.[143][64][187]

DRM-free gaming

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.[188][189]

Terminal gaming

Terminal gaming is the playing of text-based games from within a console,[190] often programmed within Bash or using libraries such as ncurses.[191][192]

Retro gaming

Retrogaming is the playing of older games[193] using emulators such as MAME or Dosbox,[194] compatibility layers such as Wine and Proton,[195] engine reimplementations and source ports,[196] or even older Linux distributions (including live CDs and live USB, or virtual machines),[197] original binaries,[198] and period hardware.[199]

Live gaming

A number of games can be played from live distributions such as Knoppix, allowing easy access for users unwilling to fully commit to Linux.[200] Certain live distros have specially targeted gamers, such as SuperGamer and Linux-Gamers.[201][202]

Browser gaming

Browser gaming is the act of playing online games through a web browser,[203] which has the advantage of largely being platform independent.[204][205] The same largely applies to social network games hosted on social media sites.[206] Older games were largely based on Adobe Flash,[207] while modern ones are mostly HTML5.[208]

Cloud gaming

Cloud gaming is the streaming of games from a central server onto a desktop client.[209] This is another way to play games on Linux that are not natively supported,[210][211] although some cloud services, such as the erstwhile Google Stadia,[212][213] are hosted on Linux[214][215] and Android servers.[216] GamingAnywhere is an open source implementation.[217]

On Windows

Although less exploited than the reverse,[218] as few programs are Linux exclusive,[219] support does exist for running Linux binaries from Windows.[220][221] The Windows Subsystem for Linux allows the running of both command line[222][223] and graphical Linux applications[224][self-published source?][225] from Windows 10 and Windows 11.[226] An earlier implementation is Cygwin,[227] started by Cygnus Solutions and later maintained by Red Hat,[228] although it has limited hardware access[229] and required adaptation.[230] The use of Wine can even allow for the running of Windows games on Linux from Windows.[citation needed] The LibTAS library for tool assisted speedruns currently recommends WSL to run on Windows.[231] Naughty Dog meanwhile have used Cygwin to run old command-line tools for use in their game development,[232] which is a broader use for the platform.[233] 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,[234] though it has speciality uses.[235]

Android gaming

Originally derived from Linux, the Android mobile operating system has a distinct and popular gaming ecosystem.[236] It has also been used as the base for several game consoles, such as the Nvidia Shield Portable and the Ouya.[237] Popular games include Pokemon Go, Genshin Impact, League of Legends, Dead Cells and Call of Duty.[238] Certain games, such as Minecraft, Stardew Valley, and Papers Please, are available for both Android and desktop Linux.[239]

BSD gaming

Owing to a common Unix-like heritage and free software ethos, many games for Linux are also ported to BSD variants[240] or can be ran using compatibility layers such as Linuxulator.[241] The Homura launcher exists to facilitate running Windows games through Wine,[242] which can still be used standalone.[243] A 2011 benchmark by Phoronix even found certain speed advantages over running games on Linux itself, comparing PC-BSD 8.2 to Ubuntu 11.04.[244] The permissive licensing of BSD has also lead to its inclusion in the system software of several game consoles, such as the Sony PlayStation line[245][246] and the Nintendo Switch.[247]

Unix gaming

A further niche exists for running games, either through ports or lxrun,[248] on Solaris[249] and derivatives such as OpenIndiana,[250] Darwin distributions such as PureDarwin,[251] HarmonyOS[252] and OpenHarmony,[253] Coherent,[254] SerenityOS,[255][256] Redox OS,[257] ToaruOS,[258] Xv6,[259] Fiwix,[260] or on Minix[261] and Hurd based systems.[262] There has been some cross-pollination with purely proprietary Unix derivatives,[263] such as AIX,[264] QNX,[265] Domain/OS,[266] HP-UX,[267] IRIX (see here),[268][269] Xenix,[270] SCO Unix,[271] Unixware,[272] Tru64 UNIX,[273][274] LynxOS (which features inbuilt Linux compatibility[275]), Ultrix,[276] OpenVMS,[277][278] z/OS UNIX System Services,[279][280][self-published source?] and even A/UX.[281][self-published source?] The games Doom and Quake were developed by id Software on NeXTStep,[282] a forerunner of modern macOS,[283] before being ported to DOS and back to numerous other Unix variants.[284] This involved reaching out to numerous Unix vendors to supply machines to use in the build and testing process.[285]

Social gaming comes in many forms, but an obvious example would be games that can be played on Facebook and other social networking websites where games and statistics can be viewed and shared online with a player’s friends. This form of gaming is very limited as the games that can be played via social networks are usually targeted towards casual gamers and not the hardcore PC type. I don’t see social gaming becoming an immediate threat to native gaming in the near future and will probably remain a casual space."
