Steam is a video game digital distribution service and storefront developed by Valve Corporation.

In addition to distributing games and apps, Steam also offer various features, including achievements, social networking and game streaming. Steam can also support CD-key activation for games and apps, and third-party stores like Humble Bundle do distributes the CD-keys. Steam also has its own controller wrapper, the Steam Input, for better compatibility with third-party, non-XInput controllers. Cloud save is supported with Steam Cloud.

Games and apps distributed through Steam are usually protected with Steam's own DRM. It should be noted that some games are either DRM-free or protected with third-party DRM. (See DRM-free and contain third party DRM for more info.) In addition, Steam has its own anti-cheat measure in the form of Valve Anti-Cheat, which can apply to the whole Steam account if a user was caught using cheat software in VAC-enabled games.

To protect user from having their account hacked, Steam also support two-factor authentication using either the email or the dedicate Steam mobile app's Steam Guard authentication function.

Steam was launched on September 12, 2003 for Windows PCs, initially only for Valve-published games. It was later expanded to distribute third-party titles in late 2005, with major publishers began to publishes their games on Steam in 2007. The MacOS and Linux versions of the client were launched on May 12, 2010 and February 14, 2013 respectively.

Over the years, support for older operating systems were dropped, with Windows 9x in 2007, Windows XP SP1 in 2012 and Windows XP/Vista on January 1, 2019. Support for Windows 7, Windows 8 and Windows 8.1 were planned to end in 2024.

On Linux OS, it is recommended to install Linux Steam Integration for better integration. Third-party clients, such as the Flatpak version of the client, is available at the FlatHub database, though it is noted that most games have issues with the Steam Cloud sync when using the Flatpak client. For better security, it is suggested to follow the Snap version progress.

Big Picture

Big Picture is a 10-foot user interface mode of the Steam client designed for readability and interaction on a TV with a game controller; although it supports keyboards and mice and is accessible on all computers and form factors as well. Most features and functionality of the desktop mode of the client is supported in Big Picture mode as well, although a few limitations might exist (such as the inability to configure Steam Cloud synchronization). Big Picture mode is also the UI that Steam will launch and make use of when streaming to the Steam Link streaming box.

See PC gaming on a TV and couch for general setup information.

Allows Steam to be used with a controller.

Open Big Picture mode from desktop mode:

Launch Steam. Open Big Picture mode using one of these ways: Click on the Big Picture Mode icon (a gamepad), usually located in the upper right corner of the Steam window. Open the View menu and select Big Picture Mode. Push Alt+↵ Enter while the Steam window have focus. Push the home/guide button on a controller while the Steam window have focus. Big Picture should now have opened. If you need to return to desktop mode; on the start screen, open the Power menu and select Exit Big Picture.

Family Sharing

Allows sharing games between accounts. Each account gets separate saves (if supported by the game), achievements, et al. except for DRM keys, which are shared.

If the account's main owner is playing a game from their own account, or someone else is using family share on that account, you are presented with the "buy" option instead of install/play for the selected game.

VAC bans can apply to the both the perpetrator and the owning account of a shared game, and the Family Share feature can be revoked entirely.

Games with 3rd party DRM tied to account-locked keys (such as Ubisoft Connect), have the feature specifically turned off by their publisher.

Instructions[citation needed]

Log into your Steam account and press Authorize this computer if shown in Settings->Family. Log out and into the account to want to share with, go to Settings->Family, press Authorize this computer if shown, and for each account in Eligible accounts you want to share with ensure the Share box is enabled. Log back into your main account, go to Library and select Games from the drop down, and you should see games categorized as MY GAMES for games belonging to your account and [USER]'s Games for each family shared account.

Offline Mode

Offline Mode is a mode of Steam where installed games can still be accessed and played without an online connection. It is mostly relevant when users have limited or no Internet access, and will automatically be engaged when the client detects that there's no Internet access available.

Requires the user to have signed in and launched downloaded games at least once with online connectivity in advance to properly configure both the account and the individual games for offline play.

The Steam installation under <Steam-folder> is portable, meaning that it can be copied to any PC and Steam will start normally. This way, every game with standard Steam DRM can be played on another computer without internet connection, if you login into offline mode successfully. In case the Steam client wants to check for updates after startup, which can prevent the offline mode from working, see Disable client update check on startup.

Additional third-party DRM (including Steam CEG) might prevent offline play. Certain use of the Steam Cloud and/or Steam API can also inadvertently prevent offline play (e.g. Mega Man Legacy Collection 2 and Caladrius Blaze).

Prepare Steam and games for offline mode

Open Steam while being connected to the internet. When logging in tick the Remember my password checkbox. Run downloaded games at least once to ensure they're properly configured for offline mode. On the top left, select Steam and Go Offline. Verify that Steam can sign into offline mode, and that downloaded games are accessible as well. Alternatively, you can skip the above steps (execpt 3.) by setting WantsOfflineMode to 1 in <Steam-folder>\config\loginusers.vdf. This starts Steam in offline mode automatically, as long as you haven't activated the "Don't save account credentials on this computer" setting in the Steam Account configuration.

Notes

Start dialog box can be removed by setting SkipOfflineModeWarning to 1 in <Steam-folder>\config\loginusers.vdf. Note that this setting gets reset to 0 after Steam quits.

Steam Cloud

For a list of games, see games using Steam Cloud over on the Steam storefront. Some games might not be listed even though they use the feature.

Steam Cloud is a feature of the Steam client that allows game data to sync between players' computers by uploading it to the online Steam platform after a game has been played, and downloading/synchronizing the local data when the Steam client or the game is launched. The implementation of the feature is game-specific and up to the developers of the game. Some developers choose to only sync save game data, or both save game data and configuration files, yet others force users to choose only a single slot to be synced. Some games list Steam Cloud as a supported feature, but do not sync any data whatsoever. An examples of such a game is Capsized.

Automatically backs up saves/settings on supported games.

Not every game is supported; up to the developers to implement it and decide on to sync.

Can only be toggled through the desktop mode of the Steam client.

Location

The below table lists where Steam Cloud data may be stored for games locally.

Note that games rarely use these locations for the actual local storage of their save files and configurations; which is most often saved elsewhere. If save games or configuration files can be seen here, chances are those files are merely cached copies used by Steam Cloud of files stored elsewhere (e.g. in %USERPROFILE%). They are often not an indication that a game works directly toward these locations.

System	Location
Windows	<Steam-folder>\userdata\<user-id>\<app-id>\
Linux	$HOME/.SteamCloud/<user-id>/<app-id>/[citation needed]
macOS (OS X)

Subfolders

• remote - Contains locally cached data synchronized with Steam Cloud. Files contained within are synchronized with the cloud servers before a game is started or after it is closed.
• local - Contains data not meant to be synced towards Steam Cloud. This folder is rare, and is often an indication that a game uses Steam Cloud as its primary storage, and does not store save games or configuration files elsewhere.

Game-specific setting

Disabling the feature system-wide takes precedence over the game-specific setting.

Toggle the feature for a specific game:
Launch Steam in desktop mode. Open the Library, Right Click on the game and select Properties. On the Updates tab, change Enable Steam Cloud synchronization for <game-title> as desired. Click Close to save the changes.

System-wide setting

Toggle the feature system-wide:
Launch Steam in desktop mode. Open the View menu and select Settings. On the Cloud page, change Enable Steam Cloud synchronization for applications which support it as desired. Click OK to save the changes.

Delete files stored in the cloud

Upload empty files

Make sure that Steam Cloud is enabled in the game whose files you want to delete. Close Steam. Navigate to <Steam-folder>\userdata\<user-id>\<game-id>\remote\. Erase the contents of every file present within the remote folder with a text editor. This can be achieved quickly in Windows PowerShell: Hold shift and right-click on your remote folder. Select the option “Open PowerShell window here”. Once PowerShell is opened, type: clc –path "<Steam-folder>\userdata\<user-id>\<game-id>\remote\*". Launch the game whose files you want to delete. Once the Cloud conflict error is forth, don’t click any option. Navigate to <Steam-folder>\userdata\<user-id>\<game-id>\ and delete its contents (remote and remotecache.vdf). Go back to the conflict window and select the option of Upload to the Steam Cloud. Now Steam will sync your AppID folder while there will be nothing in it and the previous data on your Steam Cloud will be deleted. Now the game will start automatically, but it will create new files that will be synced to your Steam cloud when you close it. Exit the game by pressing Alt+Tab ↹. Select the Steam client and disable Steam Cloud. Now return to the game and exit. To make sure if it worked you can go to https://store.steampowered.com/account/remotestorage and see if the game is there. Cloud conflict error may not work if it is the first time launching the game after installation.

Games without a remote folder

Make sure that Steam Cloud is enabled in the game whose files you want to delete. Close Steam. Navigate to the save game location. Erase the contents of every file present within the folder with a text editor or Windows PowerShell. Launch the game whose files you want to delete. Once the Cloud conflict error is forth, don’t click any option. Navigate to <Steam-folder>\userdata\<user-id>\<game-id>\ and delete remotecache.vdf). Navigate to the save game location and delete all the files in it. Go back to the conflict window and select the option of Upload to the Steam Cloud. Now Steam will sync your save folder while there will be nothing in it and the previous data on your Steam Cloud will be deleted. Now the game will start automatically, but it will create new files that will be synced to your Steam cloud when you close it. Exit the game by pressing Alt+Tab ↹. Select the Steam client and disable Steam Cloud. Now return to the game and exit. To make sure if it worked you can go to https://store.steampowered.com/account/remotestorage and see if the game is there. Cloud conflict error may not work if it is the first time launching the game after installation.

Steam Community Overlay

The Steam Community Overlay is an in-game overlay component of Steam that is available in all supported games launched through the Steam client. It enables users to access the Steam Community platform, list of achievements for the game, the Steam Chat, a general-purpose web browser, as well as a FPS counter OSD, all without leaving the confines of the game window. It also features in-game notifications for events such as achievement unlocked, invite received, new chat message, etc. Most common graphics APIs are supported, and compatibility with games are quite high.

Used by Steam Input, Steam Controller, and in-game features like DLC purchase, game invites, screenshots, etc. Disabling the overlay globally or game-specific will limit the functionality within affected games.

Add an external game to the Steam Library as a Non-Steam Game and launch it through Steam to allow the use of the Steam Overlay within the external game.

Toggle using ⇧ Shift+Tab ↹ or the Home/Guide button on a controller.

Game-specific setting

Disabling the feature system-wide takes precedence over the game-specific setting.

Toggle the feature for a specific game:
Launch Steam in desktop mode and open the Library. Right Click on the game and select Properties. Under the General tab, change Enable the Steam Overlay while in-game as desired. Click Close to save the changes.

System-wide setting

Toggle the feature system-wide:
Launch Steam in desktop mode. Open the View menu and select Settings. On the In-Game page, change Enable the Steam Overlay while in-game as desired. Click OK to save the changes.

Steam Input

Steam Input is a feature of the Steam client and an umbrella term referring to the entire collection of software, hardware, and configuration utilities that Steam uses to interface with games. It acts like a wrapper using the Steam Community Overlay to intercept and manipulate player input before passing it on along to the game. This allows it to bind certain game-specific actions to specific inputs (on games that supports action-based input), or to add or extend the functionality of input devices in various ways, such as adding XInput, keyboard, or even mouse support to input devices that otherwise would not support them. The feature was previously known simply as Steam Controller as there was no distinction from the controller with the same name and its supporting environment and features, which eventually was renamed to Steam Input.

Disabling the Steam Community Overlay prevents Steam Input from being active as well.

Allows supported input devices that lacks native XInput support to function in XInput-based games.

Can interfere with the functionality of a controller in some games, based on Steam Input configuration and whether Steam Community Overlay is enabled for the game or not.

See the Steam Input section of the Steamworks documentation for much more in-depth information.

Steam Input API

For a list of games, see List of games that support Steam Input API.

Steam Input API (SIAPI, previously known as Steam Controller API or SCAPI) refers to the accompanied API that games can make use of to add support for action-based input, as opposed to button-based input. The main difference from other APIs like XInput and DirectInput is that when a game implements support for the Steam Input API the game itself does not need to add support for any particular input device or method. Instead the Steam Input layer and API acts as a hardware abstraction layer and converts the input received from a supported input device to the proper game-specific action the user has configured the input to. This means that when Steam adds more supported input devices or methods to the Steam Input layer, games will automatically support those new devices and methods without any additional development time required by the game developers.

Controller Configurator

The Controller Configurator in native mode using a Steam Controller.

The Controller Configurator in legacy mode using a Steam Controller.

How the game-specific controller configurator functions depend on the level of support the game have for Steam Input. Refer to supported games for details.

Community configurations and pre-built templates (from either Valve or the game developer) are available and can be adjusted to one's liking.

Steam Controller Configurator is used to rebind actions (for games that natively support the Steam Input API) or buttons (for games that do not natively support the API). If a game does not support the Steam Input API natively, the Steam Controller Configurator will fall back to a "legacy mode" where the user can instead rebind buttons on their controllers (e.g. bind Numpad 5 to X on the gamepad) as well as tweak various functionality of their controllers (e.g. rapid fire, deadzone, sensitivity etc).

Open controller configuration for compatible controllers:

Verify that a compatible controller is connected and support enabled for it, see Supported input devices for details. Open Steam Access Controller Configuration depending on which configuration you want to customize: Game-specific configurations: In desktop mode: Library -> select game in details view -> click on Controller Configuration under Links In desktop mode: Library -> right-click on the game -> Edit Steam Controller Configuration In Big Picture mode: Library -> select game -> Manage Game -> Controller Configuration Big Picture, Desktop, or Guide Button Chord configurations: In desktop mode: View -> Settings -> Controller -> appropriate configuration In Big Picture mode: Settings -> Base Configuration -> appropriate configuration Notes The Controller Configuration option will not show or be accessible if a compatible controller was not found attached to the system, or if support for the aforementioned controller type has not been enabled (not applicable for the Steam Controller).

Supported configurations

Steam Input supports four different configurations, three of which are known as "base" configurations while the one remaining is game-specific. What configuration is currently active depends on what environment Steam Input currently believes it is being used in, using the Steam Overlay to properly detect games. This can result in scenarios where the desktop configuration is applied for a game because the Steam Overlay is disabled or not functioning properly for the game.

Configuration	Explanation
Game-specific	Used when Steam Input detects the presence of a game. The actual configuration is game-specific.
Big Picture	Used for Big Picture mode of Steam.
Desktop	Used while outside of a game, on the desktop of the operating system. Will be used if Steam Input fails to properly detect a game.
Guide Button Chord	Global accessible override configuration by holding down the Guide/Home button of the controller. Can result in unwanted input if accidentally triggered while turning off certain wireless controllers.

Supported games

Some games might not natively support Steam Input API but still provide button prompts for the Steam Controller, see the Steam Controller article for more information.

Subreddit with a list of games with native/official bindings support

All games the Steam Community Overlay is capable of hooking are supported; although the level of support varies based on the game-specific support for the Steam Input API.

Support	Mode	Rebind	Explanation
Native Steam Input API support	Native	Actions	The game supports Steam Input API and allows for full use of the controller configurator for all compatible devices. The game can include native button prompts, action sets, haptic feedback and official configurations with aliased text for games features. For a list of games, see List of games that support Steam Input API support.
No Steam Input API support; provides official bindings	Legacy	Buttons	The game does not support Steam Input API, however it does provide one or more official controller config(s) for the configurator. For a list of games, see List of games that support Steam Input presets. Supported input devices will be limited to emulating XInput and/or mouse/keyboard input.
No Steam Input API support	Legacy	Buttons	The game does not support Steam Input API nor provide any official config for the controller configurator. The user has to use a community-created config or create their own. Supported input devices will be limited to emulating XInput and/or mouse/keyboard input.

Toggle Steam Input for a specific game:

Open Steam and navigate to the game-specific controller options: In desktop mode: Library -> right-click on the game -> Properties In Big Picture mode: Library -> [desired game] -> Manage Game -> Controller Options Configure Steam Input Per-Game Setting as desired: Global setting (None or PS4/XBox/Generic/Switch) - Uses the global configuration. Note that even if set to None, Steam Input might still be active in certain cases (e.g. launchers). Forced Off - Forcefully disables Steam Input. This option prevents Steam Input from being active in launchers as well. Forced On - Forcefully enables Steam Input. Click OK or Close to save the changes. Restart the game if it is currently running. Notes The option is only exposed in desktop mode if using the latest Steam Beta client. The option was called Use Steam Configuration for Non-Steam Controllers before being renamed to Steam Input Per-Game Setting late 2018.

Supported input devices

Supported style of input options differs based on the controller. Refer to the controller-specific page for more information.

Enabling controller support can cause double input or similar input issues in certain games, or while using certain configurations for the controller.

In some instances Steam Input will be enabled for a controller even without the user having explicitly enabled support for it. This is typically seen in games where developers have expressively tagged them as requiring Steam Input to support certain types of controllers, as well as in external configuration tools or launcher where Steam Input automatically uses the desktop configuration to spoof mouse and keyboard input, even for controllers without enabled support. Forcefully disabling Steam Input for that specific game is necessary to circumvent this behavior.

To make use of the Steam Input feature users must have a compatible Steam Input device, such as the Steam Controller, DualShock 3, DualShock 4, Dualsense, Dualsense Edge, Switch Pro controller, Xbox 360 controller, Xbox Wireless controller, Xbox Elite controller, Xbox Elite Series 2 controller, Amazon Luna Controller or any other generic XInput or DirectInput controller. However only support for the Steam Controller is enabled by default; support for all other compatible controllers must be manually enabled within Steam before the controller can make use of the features.

Enable controller configuration support for compatible controllers:

Turn off or disconnect the controller from the computer. Open Steam and navigate to the controller settings page: In desktop mode: View -> Settings -> Controller -> General Controller Settings In Big Picture mode: Settings -> Controller Settings Enable the proper configuration support based on the controller: Xbox Configuration Support - Xbox 360 controllers, Xbox Wireless controllers, or any other XInput controllers. Xbox Extended Feature Support Driver - This option install a special driver that enable Steam to support additional features, such as remapping back paddles on the Xbox Elite controller and Xbox Elite Series 2 controller, as well as provide impulse triggers support for supported games without the need of disable Steam Input. PlayStation Configuration Support - DualShock 4, or any variant devices that use the same input protocol. Some games can use the Steam Input API to support DualSense's adaptive triggers, and the DualSense Edge's back buttons and FN buttons can be remapped in the controller configurator. It also supports DualShock 3, but requires the official Sony drivers for the controller obtained through Playstation Now. Switch Pro Configuration Support - Switch Pro controllers. Generic Gamepad Configuration Support - Any DirectInput controller. Turn on or connect the controller to the computer again. Steam should now detect the controller and allow it to use Steam Input features.

Steam Play

ProtonDB - Community-driven database of Proton compatibility for games.

Steam Play refers to features and functionality of Steam that allows some form of cross-operating system access to purchased games. Back in 2010 when the feature was first announced it referred to titles where a single purchase regardless of operating system granted users access to versions of that game on other operating systems as well, thereby making OS transitions easier as purchased games did not have to be purchased anew for the new operating system.

On August 21, 2018, Valve announced a new version of Steam Play that focused on enhancing and integrating existing third-party Windows compatibility layers and wrappers for Linux into the Steam client and games. It makes use of Proton, a tool that is based on a custom version of the compatibility layer Wine as well as additional libraries developed alongside it and the Vulkan-based Direct3D 11, 10 and 9 translation layer; DXVK. Some of the improvements include a Vulkan-based Direct3D 12 implementation called vkd3d, as well as the "esync" patchset to improve multi-threaded performance in Wine. Proton is available to use through the Steam client on Linux for both officially supported Proton compatible titles, such as DOOM (2016), as well as third-party titles that Valve have not yet verified compatibility with (such as HITMAN2).

Other information

Change the language of a game

Instructions

Right Click on the desired game in the Library. Select Properties, the Language tab, then select the desired language. Notes Changing a game's language might not be possible while the game is already open. It's also possible to change the language by editing the language parameter of the relevant appmanifest_<app-id>.acf. For some games this can allow additional options not available through the UI, such as with Child of Light.

Playing without game updates

The Only update this game when I launch it option does not allow playing without updates; the only way to avoid updates is by playing in Offline Mode.

Some developers make earlier versions available under the Betas tab in the game's properties in the Steam client. Once selected and downloaded, this alternate version can be played without further updates.

It is possible to download older game versions and play the older version indefinitely (unless external game-specific services prevents it) if it is stored in another location than the download or game folder.

Download older game versions

Downloading an older version of a game requires a full download of the specific version and sufficient free space on your device. The download does not overwrite existing game files.

There's no way to monitor or throttle the download progress without using external third-party tools.

Take note of the required information
Search for the game on SteamDB. Take note of the app ID. Switch to the Depots tab and open the depot(s) with the required files to downgrade. Take note of the depot(s) ID. On the pages of the aforementioned depot(s), switch to the Manifests. Take note of the manifest IDs of the desired version.

Download using Steam's console

Enter steam://nav/console on the web browser. Steam will now have a Console tab. On Steam's console, enter the following command: download_depot <app-id> <depot-id> <manifest-id> <app-id>, <depot-id>, and <manifest-id> are the IDs noted from SteamDB, from step 1, 2, and 3 respectively. If executed properly, the console will print: Downloading depot <depot-id> (<size>). Wait for the download to complete. Do not close Steam or shut down the computer as this will terminate the download! When the download is finished, the following line will be printed in the console: Depot download complete | "<download-path>" (<depot information>). Open the indicated download folder. You can now move the contents of the folder to a more proper location.

Download using DepotDownloader

Disclaimer: The tool requires your Steam username, password, and Steam Guard authentication token to function. PCGamingWiki cannot make any guarantees regarding the safety of the tool. Use at your own risk! Download the latest version of DepotDownloader and extract it to any location. By default downloads will be stored in a subfolder of DepotDownloader so be sure to extract it to a drive with enough space to download all files. Navigate to the extraction target folder where DepotDownloader.exe is located. Hold down ⇧ Shift and right click in the folder itself, without selecting any specific files. If done correctly, a few new options will be available in the context menu. Select the Open PowerShell window here option. Enter the following command: .\DepotDownloader.exe -app <app-id> -depot <depot-id> -manifest <target-manifest-id> -username <username> -password "<password>" -validate <app-id>, <depot-id>, and <manifest-id> are the IDs noted from SteamDB, from step 1, 2, and 3 respectively. <username> is your Steam username (not to be confused with your profile name). <password> is the password of your Steam account. -dir <installdir> can also be used to specify a custom download target folder. If the account is protected using Steam Guard, the window will prompt for the two-factor authentication code displayed on your authenticator app. If executed properly, the console will print: Downloading depot <depot-id> - <depot description> Wait for the download to complete. Do not close the window or shut down the computer as this will terminate the download! When the download is finished, the following line will be printed in the console: Depot <depot-id> - Downloaded <size> bytes. The downloaded files will be saved in the specified folder, typically in a subfolder called depots\<depot-id>\<build-id> below DepotDownloader. Open the indicated download folder. You can now move the contents of the folder to a more proper location. See GitHub for more parameters that can be used to control what gets downloaded.

Notes

Move the older version to a folder separate from the regular version to prevent Steam from removing the older version when a new update is released. Alternatively, keep a copy of the older version somewhere else.

Some games might require a steam_appid.txt file containing the app ID and nothing else before they can be launched from another location.

Copying a game from a different computer

Instructions[citation needed]

Go to <Steam-folder>\SteamApps\common\ on the computer where the game is installed. Look for the folder that fits the game you want to copy and move it to the same location on the target computer. Go to steampowered.com in a web browser and visit the game's store page In the Url bar of your browser you'll see store.steampowered.com/app/<app-id>/, where <app-id> is a number that uniquely identifies the game on Steam. Grab the <Steam-folder>\SteamApps\appmanifest_<app-id>.acf file that fits the <app-id> from the store page and copy it to the same location on the target computer. Close and restart Steam. The game should now show up in your Library and be ready to play. (Optional) If the game doesn't run or if it came from a different OS, right click on the game in your Library and choose Properties ; then go to the Local Files tab and click on Verify integrity of game cache… . This will trigger Steam to repair the installation.

Disable client update check on startup

Instructions[citation needed]
Go to <Steam-folder> and create the file steam.cfg with the following content: BootStrapperInhibitAll=enable BootStrapperForceSelfUpdate=disable

This is especially useful when you use Steam in Offline Mode and/or want to copy your Steam installation to another offline pc.

Make sure to undo these settings, when you want to go online again, to keep the Steam client updated.

Windows			The client itself is 32-bit, despite a Steam update in 2018 that allowed Valve to update individual features to 64-bit.
macOS (OS X)			As no PowerPC client for Mac was ever released, it is unknown to which extent any PPC/Intel universal apps bought on Steam could be installed on PPC Macs.
Linux			User requests for a native 64-bit client have been denied by Valve on numerous occasions since 2014, purportedly since such a client would be unable to launch 32-bit games.

All clients can launch 32-bit and 64-bit games. Only the macOS client can launch ARM games, which it has been able to since September 2021.

SteamGet is a script created by Ryan C. Gordon (aka Icculus) which requires SteamCMD to work. What it does is that it will download all the files from the selected game you own in your account without requiring you to rely Wine to do that or use the SteamCMD itself as this script makes its task more simple. This can be very useful if you wish to use the game files for the source port of the game or an open source engine.

Optimize PulseAudio to audio in Steam games

Edit daemon.conf

Open daemon.conf file from /etc/pulse/ as root and add the following text: # Start as daemon daemonize = yes allow-module-loading = yes # Realtime optimization high-priority = yes realtime-scheduling = yes realtime-priority = 9 # Scales the device-volume with the volume of the "loudest" application flat-volumes = no # Script file management load-default-script-file = yes default-script-file = /etc/pulse/default.pa # Sample rate resample-method = speex-float-9 default-sample-format = s24-32le default-sample-rate = 192000 alternate-sample-rate = 176000 exit-idle-time = -1 # Optimized fragements for steam default-fragments = 5 default-fragment-size-msec = 2 # Volume deferred-volume-safety-margin-usec = 1 Save the file and run both pulseaudio -k and pulseaudio --start to restart PulseAudio or just reboot the system.

Use Native Steam runtime mode

Improves the performance for both games and the software itself.

Basic

Install Linux Steam Integration and enable Use Native Runtime.

Advanced

On a 64-bit system you must install the 32-bit version of these libraries: openal, nss, gtk2, gtk3, libcanberra, gconf, dbus-glib, libnm-glib, libudev0-shim and libappindicator-gtk2 (so the tray icon would work).

Some games may still require some additional libraries to work. You can use this page to learn which ones are needed for the specific software regardless of the linux distribution you are using. Most of the Ubuntu-based distros may already include them.

While the current Steam package already includes required libraries to work, they are sadly outdated as they are from Ubuntu 12.04. However, Valve included an option to force Steam to use the libraries used in your system, also known as Steam Native mode. This can be done by adding STEAM_RUNTIME=0 before the command for launching Steam.

It's best to create a separate executable file for it in order to allow easily switch between the Runtime and Native.

Create a Steam Native executable script

Open or go to /usr/bin in Terminal and type sudo nano steam-native Copy and paste this script: #!/bin/sh export STEAM_RUNTIME=0 # Workaround for dbus fatal termination related coredumps (SIGABRT) # https://github.com/ValveSoftware/steam-for-linux/issues/4464 export DBUS_FATAL_WARNINGS=0 # Override some libraries as these are what games linked against. export LD_LIBRARY_PATH="/usr/lib/steam:/usr/lib32/steam" exec /usr/lib/steam/steam "$@" Exit while saving the file with Ctrl+X and accept while leaving the name intact. Type sudo chmod +x steam-native to mark the script as executable

Once done, you will be able to run Steam Native with the steam-native command on Terminal, you can add it to the Start/Program Menu if you wish, but it is also best to add its .desktop file as well, so it'd be available and automatically added.

Create a Steam Native Desktop script
Open or go to /usr/share/applications or $XDG_DATA_HOME/applications (recommended, usually represents ~/.local/share/applications) in Terminal. Type nano steam-native.desktop. Remember to prefix this with sudo if editing within a system folder such as the first one mentioned in step 1. Copy and paste this script Exit while saving the file with Ctrl+X and accept while leaving the name intact.

Arch Linux-based distributions only require installing steam-native-runtime package which will automatically install required repositories and automatically set everything for you, once you install Steam.
