What’s actually slowing this PC down?

Yes—SteamOS can do more than launch games. On the Steam Deck, its desktop mode supports web browsing, installing applications and running programs outside Steam, while its gaming interface and Proton make it a Linux system built first around Steam. But using SteamOS on a self-built desktop is a different proposition: hardware compatibility and troubleshooting support are not guaranteed just because the PC runs Linux.
What SteamOS gives a Linux power user
SteamOS combines a controller-friendly, Steam-first gaming interface with a Linux desktop. On a Steam Deck, switching to Desktop Mode provides a conventional environment for browsing, installing applications and launching software outside Steam. Valve describes it as functioning “like a normal PC” in its Basic Use & Troubleshooting Guide.
That makes SteamOS useful for someone who wants a gaming appliance that can also handle everyday desktop tasks and tinkering. It is not, however, a promise that every Linux application, peripheral or workflow will work unchanged. Valve’s guide advises users to check whether third-party applications support Arch Linux, the environment used in Desktop Mode. Package formats, drivers, desktop integration and system updates can all affect whether a particular setup works smoothly.
How well SteamOS works on a PC depends on the PC
There is an important distinction between SteamOS running on Steam Deck or another officially powered SteamOS device and installing it on arbitrary desktop hardware. Valve’s SteamOS Installation and Repair page says recent SteamOS 3.8 updates improved compatibility with other AMD-powered handhelds and desktops. It also warns that Steam Support may have limited ability to troubleshoot issues specific to hardware outside officially powered SteamOS devices.

#1 Best Overall
- 1TB NVMe SSD
- 1280 x 800 HDR OLED display with premium anti-glare etched glass, 7.4" Diagonal display size up to 90Hz refresh rate
- Wi-Fi 6E
- 50Whr battery; 3-12 hours of gameplay (content-dependent)
- Carrying case with removable liner
So compatibility is expanding, but a self-built PC should be treated as a case-by-case project rather than a fully supported SteamOS configuration. Before installing, compare the system you intend to use against these practical factors:
- Support: Is the device officially powered by SteamOS, and who will troubleshoot problems if it is not?
- Components: Do the graphics hardware and the peripherals you rely on work with the current system?
- Games: Are the specific games you care about currently rated as compatible, and do their launchers or anti-cheat systems behave as needed?
- Workflow: Do you want a controller-first gaming interface with desktop capabilities, or a desktop-first Linux workstation?
- Recovery: Are you comfortable creating recovery media and restoring the system if installation or an update goes wrong?
Install or repair using Valve’s recovery instructions
Valve’s recovery page is the starting point for SteamOS installation and repair. It explains how to write recovery media and provides device-specific install and repair paths. Back up important content before choosing any wipe-and-install operation, and follow the instructions for the device you are actually using. A recovery image does not make unsupported hardware officially supported.

Can SteamOS run Windows games?
SteamOS uses Proton, Valve’s compatibility layer, to run many Windows games. Compatibility is assessed title by title; a game that works well does not establish that another one will. Steam’s Steam Deck Software Info & Troubleshooting Guide recommends checking the Compatibility section on each game’s Store page. If a title is marked Playable or Unsupported, inspect the listed requirements that kept it from a Verified rating.
Ratings can reflect practical friction as well as whether a game launches. Controller usability, launcher behavior, anti-cheat and game updates can affect the experience, and conditions can change. For troubleshooting, Valve suggests trying the latest Proton version. Check the individual title’s current information rather than treating a general claim about Windows-game support as a guarantee for your library.

What you need for a desktop setup
Desktop Mode can be used on the Deck itself, or with an external display and peripherals. Valve’s Steam Deck specifications list USB-C with DisplayPort 1.4 Alt Mode and video output up to 8K at 60 Hz or 4K at 120 Hz. These are stated port capabilities, not a guarantee that every dock, cable, monitor or combination will achieve those modes.
A dock or hub may be convenient if your intended setup needs more connections; it is not established as a requirement. Check the ports and supported display modes of the particular display, dock and cable before buying or troubleshooting them.
Rank #4
- Valve is entering the gaming console marketplace with the new Steam Deck, a console geared towards PC gamers. The Steam Deck can be docked to a monitor, and used as a PC, or docked to a TV.
- Players can play a huge variety of games at any time with the comfort of a console and the freedom of a PC. Not anti-glare screen.
- Like the name suggests, the Steam Deck will include upgraded 1TB storage, and will include a carrying case. A micro SD slot will also enable expanded storage.
- Valve partnered with AMD to create a specialized APU optimized for handheld gaming, and Valve says the chip will deliver performance to run AAA gaming titles.
- The Steam Deck is outfitted with a 7-inch touchscreen, and two trackpads under the control sticks that allow gamers to operate games never designed outside of mouse and keyboard capabilities.
Who should put SteamOS to work?
SteamOS is a strong fit if you want a Steam-centered gaming interface, value the option to switch to a Linux desktop, and are prepared to check compatibility for the games and applications you use. Steam Deck offers Valve’s designed-for experience; an officially powered third-party device has its own manufacturer support considerations. A self-built desktop may be appealing to a Linux power user who is comfortable testing and recovering a system, but it comes with more uncertainty around hardware and support.
If your main goal is a conventional Linux workstation that happens to play games, evaluate SteamOS against your specific desktop applications, components and support needs before replacing an existing operating system. If your goal is Steam gaming with a useful desktop mode, the Deck is the clearer route to the experience Valve documents.
