Getting started with gaming on Linux and gaming on instantOS

This article is meant to get you started with gaming on Linux as a new user coming from Windows or Consoles. It aims to build an understanding of Linux Gaming from the ground up and avoid what I call "ecosystem confusion".

You can get surprisingly deep into a piece of documentation without an overview of what anything actually does and how it relates to everything else. This guide will build up an understanding of linux gaming and hopefully equip you with the tools to troubleshoot (or avoid) your own problems.

It will also go much more in depth than most tutorials and include many tips to make and keep gaming on linux more convenient. It contains lots of information that is for some reason really hard to google for that will still benefit 99% of linux gamers. Just as an example: "How do I find the savegames for my steam games" sounds like it should be simple to google for, yet it is not and I have not yet found anyone publicly mentioning the method described in this guide.


Here is a basic overview of the ways to play games on linux

  1. Native games
    • Games from the official repositories: These can be installed using your package manager and can be launched from the super + y menu. This is the most convenient and reliable method of aquiring games. They are almost guaranteed to work and are automatically kept up to date when the system updates. However the number of games that can be installed this way is very small
    • Flatpak/AppImage/Snap games are installed from alternative package managers. They are sandboxed which means that they work on all distros and have excellent backwards compatibility. Even very old games should work on a modern os with modern hardware. The tradeoff is that these require more storage and ram than the other methods.
    • Manually downloaded games: This is the method of aquiring software that will be most familiar to windows users. Download a program from the web and run it. This is however not recommended on Linux as the game might require other things to be installed on your system and will not automatically install them. If you run into this problem, try running the game from a terminal and check if there are error messages hinting at what the game requires to be installed.
    • Steam: Steam is a very popular game store that has a native linux version. After installing steam from the package manager the experience of using it is identical to windows when it comes to games which have a native linux version.
  2. Windows games

    • Wine:
      Wine is a program that allows windows programs to run on Linux. You point it at a .exe file and it will try to run it. Using wine directly can be a bit tricky. Not all programs will work with just the stock installation of wine. Lots of games require additional windows software to be installed. This can be done with a program called winetricks. There are also numerous programs that extend the functionality of wine. dxvk allows using directx in wine, nvapi adds support for dlss and raytracing. It can be helpful to have an understanding of the workings of these individual programs but in most cases the methods below are more convenient.
    • Steam Play:
      Steam has the ability to run windows games with a feature called Steam-Play. Steam-Play makes use of a program called proton. Proton is a collection of programs like wine and dxvk along with scripts and tweaks that make them work together. Steam play also automatically installs any additional windows programs that the game might need, meaning you don't have to make use of winetricks and don't have to manually set up dxvk or change any wine settings.
    • Lutris:
      Lutris is a game launcher that can launch all game types here including windows games. It runs windows games using wine and functions as an alternative to proton. Just like proton it also sets up wine, dxvk and nvapi automatically. It also has a database of games along with user submitted installers for them. Lutris allows for much more control over your wine installation than proton. It has a user friendly graphical interface for changing wine settings and with enough tinkering allows getting almost any game to work
    • Legendary/Heroic: Heroic is an open source alternative to the epic games launcher. It can download and play games from the epic game store. It makes use of the command line tool legendary to communicate with the epic games servers. Similarly to lutris it allows configuring wine for specific games. It also has support for running games with proton which in most cases yields better results.
    • Bottles/PlayOnLinux: PlayOnLinux is a program very similar to lutris, but contrary to what the name may suggest is focussed on running non-gaming software. It probably has its uses but from my testing you have to invest a lot more time into it to get a result that is compa PlayOnLinux almost never works Better for non-gaming software
  3. Using the official repositories. There are some games that are completely free and open source. These are available in the default repositories (aka App store). But because most games are commercial products, this leaves you with a very small library of titles that are often just tech demos for game engines that have not aged well...

  4. Steam native: Steam is a digital games store that has excellent support for Linux. It has hundreds of thousands of high quality games, many of which run on Linux.
  5. Steam Play: Linux has the ability to run Windows games using a tool called proton. It is developed by Valve and is to wine what Linux Distributions are to the Linux kernel. The steam client has a feature called steam play that allows downloading windows games from steam and playing them using proton. By default, steam play is only enabled for titles that are guaranteed to work, but you can enable it for all games in the settings. Many games are only unofficially supported but run just fine using proton. Protondb is a website that lists games and how well they run using proton.
  6. Lutris: Lutris is a game launcher with a corresponding website which contains thousands of community made installers. It allows playing native games, can be used as a launcher for steam games and games running in an emulator and most interestingly, comes with its own wine versions.
  7. Legendary/Heroic: Heroic is an open source reimplementation of the epic games launcher. It allows you to download games from the epic game store and play them using wine or proton. It utilizes the command line program legendary to handle communication with the epic games servers. It is also possible to use legendary directly without going through the heroic launcher

Wine is a program that allows using windows programs on linux. It is different from an emulator because it runs on bare metal and achieves near native performance, sometimes even surpassing windows.

In basic terms, programs can defer some tasks to the operating system so that the developer doesn't need to worry about them too much. This includes things like sound, windowing and basic GUI elements. The problem is that the instructions that programs can send to windows are different than those that linux accepts. The job of wine is to catch these instructions and translate them into their linux equivalent.


One difference between Windows and Linux is that Linux does not have a C-drive and the folder structure is different. Wine solves this problem through a feature called prefixes. A wine-prefix is a folder on your harddrive that wine uses as a virtual C drive. Everything that a program would write to the c drive if it were running on windows gets written to the prefix folder instead. This opens up interesting possibilities as each prefix acts as a separate installation of windows. In contrast to a real windows installation however a wine prefix is only in the hundreds of megabytes and can be created and deleted quickly and cheaply.


The two main versions of wine are stable and staging. Stable is the standard version which is missing the latest features but the features that are there can generally be relied upon. Staging is a version ahead of the stable version and contains unstable versions of features that will eventually end up in stable. Proton, which will be covered later also contains a version of wine with some custom patches.

Steam Play

Steam Play is a feature included in the steam client for linux that allows playing windows games on linux through a program called proton. SteamPlay automatically installs any windows programs a game might need meaning you do not have to mess with winetricks to get a game working.

Verified titles

Titles verified to be working with SteamPlay are listed on the steam store and can be launched from the library as if they were native. Any hacks and extra steps will automatically be applied.

Unverified titles

It is possible to use SteamPlay with any steam game regardless of wether it has been verified by valve. This can yield mixed results but in most cases proton is mature enough to at least get you a playable experience. To use this, go to settings->steam Play->Enable steam play for all other titles. Also make sure that the proton version beneath that checkmark is set to the latest one available

Titles not on steam

It is possible to play games not aquired from steam and even other game stores like ubisoft connect through proton inside the steam client. Steam has a built in menu to add non-steam games to the library. However the GUI for this is buggy and confusing and should best be avoided.

//TODO describe steam UI issues

Instead there is a tool called steamtinkerlaunch. Install it using yay -S steamtinkerlaunch and then run steamtinkerlaunch addnonsteamgame in a terminal. This opens up a dialog. Set the game name, set Exe to the location of the .exe file of the game and click create. Start steam-runtime and the game should be in your library. Finally, right click on the game, go to compatibility and check "force the use of a specific Steam Play compatibility tool". Select A proton version as the compatibility tool, in most cases proton experimental or proton-ge works best. After that the game should be playable on steam.

Where is the wine prefix?

You might notice that proton does not use ~/.wine as a wine prefix

//TODO link to explanation of wine prefix

proton creates a separate wine prefix for each game, located in ~/.local/share/Steam/steamapps/compatdata/gameid

Unfortunately all games just have meaningless id numbers as folder names making it quite hard for beginners to figure out which folder contains the data for which game. The steam client does not have any features to get the ID for a game and especially for non-steam games the IDs cannot even be googled for as they are unique to your installation.

The solution is a tool called protontricks. It can be installed from the AUR and running it from a terminal brings up a window which lists all games along with their name, icon and ID. inside the id folder there is a folder called pfx which is a normal wine prefix and contains the savegame at the same path where it would be on windows. You can also add the pfx folder as a wine prefix to ludusavi to keep track of your save files.


Proton is a collection of programs and scripts developed by valve that work together to make windows games run on Linux. It includes wine, dxvk openxr and many more. While the versions of programs included in proton might have a few patches applied to them it is important to mention that proton is not a fork of wine. Valve made proton work so well by contributing improvements to wine and dxvk which in turn benefit all projects making use of them, not just proton.

//TODO more stuff

Proton is not meant to be used outside of SteamPlay. Apart from steam and heroic there aren't any well maintained wrappers for proton. Using it manually is a chore and whenever you do anything wrong it hard crashes. Manually using proton requires knowledge of the source code and it requires less time and effort to use wine through lutris.


protonup is a simple program used to manage and update your wine and proton installations in steam, lutris and heroic.


Thomas Crider, also known as GloriousEggroll is a RedHat Engineer who maintains a fork of wine and a fork of proton based around that fork of wine. These versions are more up to date than their lutris and valve counterparts and contain game specific fixes and optimisations. They also have support for AMD FSR which allows running any game at a lower resolution and then upscaling it to the native monitor resolution. This allows for more performance while only losing a small amount of detail.

Console emulators allow you to play console games on your PC. This practice isn't unique to Linux. There are emulators available for linux, windows, macos, android and even for newer consoles. There are lots of resources on emulation in general so this wiki will only cover linux specific things to keep in mind when doing emulation on Linux.


Dolphin is a Wii and GameCube emulator. It is one of the most polished and maintained emulators available and the native linux version runs great.


Retroarch is a multi-system emulator. It can emulate a wide range of different consoles through a single application. It is available for tons of different platforms and works basically the same everywhere. Yet, there are a few mention worthy differences to the linux version.

No Core-Updater

The windows and android version of Retroarch have a Menu entry that allows downloading new cores (Cores are basically the runtimes for consoles). This option is not present on Linux which can frequently trip up new users. Installing new cores is done through the package manager. Cores typically have the name libretro-corename.

Missing icons and fonts

Your installation of retroarch might also have a bunch of missing icons and fonts. This is because retroarch offers multiple different graphical user interfaces and installing all of them even though only one of them will end up being used is a waste of storage. Just like the cores these cannot be aquired through a menu inside of retroarch and instead are also present in distro packages. To install the missing parts of the default user interface install retroarch-assets-ozone


Cemu is a Wii U emulator. At the time of writing it is only available for Windows. However, it runs nearly perfect using Wine.




Cemuhook works perfectly as of wine 7.1

Using a smartphone as a motion sensor works like on Windows

Cemu has native vulkan support that works great through wine. OpenGL performs worse and less reliable. Make sure that Graphics API is set to Vulkan in options->general settings->Graphics


The Cemu team has published plans to make Cemu open-source and to create a Linux Port. This page was written in February 2022 and might be outdated once the Cemu team (hopefully) follows through on their plans


Poor performance on older kernels

From around 2020 to the beginning of 2021 Cemu had massive performance issues on Linux. I have not tested if the issue was eventually fixed by a driver, wine, kernel or cemu update. If you are experiencing poor performance with Cemu on Linux, try using an arch based distro or Ubuntu Release newer than 20.04.

Dualsense Controller Support

The PS5 Dualsense controller does not work out of the box and requires extra setup. It gets detected as a valid sdl controller but does not have correct input mapping. This issue can be fixed by using ds360 //TODO add link


Which Desktop environment/Window manager

Desktop environments are usually not a good choice for gaming because they have higher latency than window managers and often have mouse accelleration enabled. Games windows often behave in strange ways that desktop environments are often not tested for. Examples of odd behaviour games might show on desktop environments but not on most window managers include: - Fullscreen windows appearing on the wrong monitor and not being able to move them - Fps games being unable to trap the mouse cursor. This causes it to leave the game window when doing a big enough turn which then means left clicking makes the game lose focus and you need to refocus it to regain control - Fps games trapping the mouse on the wrong monitor. This causes the game to lose focus everytime you left click as you are unable to move the cursor onto the game window - Forced compositing which can cause frameskips and sometimes forces vsync - Mouse inputs on fullscreen being offset or not registered at all - Some windows are immovable

The two best environments for running games are from my testing i3 and instantwm

But window managers are hard...

Games represent a unique use case for window managers because they only require really basic knowledge of a window manager to play games on it and because you are spending all your time in a single window you can even be really slow at using them and it doesn't matter because you will only need to use them to open and close the game. In the case of instantWM you do not even lose most of the perks afforded by a desktop environment.


I will concede the position of best window manager for gaming to i3wm. Despite my best efforts, it is better than instantwm if all you are doing is playing a game. Just like instantwm it has the ability to move fullscreen windows between monitors and workspaces and can force arbitrary window sizes on games. Its latency is comparable to that of instantWM

It does however include a few features that make its game compatibility outgrow that of instantWM. i3wm includes an automatic workaround for wine windows going black after losing focus. It does not have problems with mouse inputs being offset which some games have on instantWM. Some window events on wine can cause windows to become immobable on desktop environments and drift downwards on instantWM. i3wm does not have those issues and also supports moving wine windows by their native titlebar. i3wm also has a systray which not all desktop environments have and which can be a bit buggy with wine applications


//TODO proper shortcut markup

After losing focus some wine windows can go completaly black and freeze. This issue is resolved by minimizing the window with super+ctrl+h and restoring it with super+ctrl+down. Some window managers, including dwm lack the ability to minimize windows which makes them unfit for many windows games.
