When Valve announced the Steam Deck in 2021, the prevailing reaction was skepticism. A handheld PC running Linux that could supposedly play AAA Windows games on the go, sold by a company whose previous hardware ventures included the Steam Machine (mostly forgotten), the Steam Controller (cult favorite, discontinued), and the Steam Link (eventually replaced by an app). The track record was not exactly spotless.
Three years later, the Steam Deck is the dominant handheld PC, has spawned a whole category of competitors, and quietly did more for Linux gaming than the previous two decades of advocacy put together. Worth looking at what Valve actually got right.
The hardware bet
The original Deck shipped in February 2022 with a custom AMD APU, 16GB of RAM, a 7-inch 1280x800 display, two trackpads, four back buttons, and a 40Wh battery that promised "two to eight hours" of gameplay depending on the title. The first wave was hampered by supply chain issues and a backlog that took most of 2022 to clear.
The hardware design was unusual. Most handhelds before the Deck had been built around mobile chips with weak GPUs, like the Nvidia Shield or the Razer Edge. Valve went the other way and put a desktop-class GPU into a battery-powered handheld. It was thicker than competitors, heavier than competitors, and ate battery faster than competitors. It also played Elden Ring at 40fps, which competitors could not.
The trackpads were the most controversial decision. Valve had been pushing trackpads since the Steam Controller, and the conventional wisdom was that nobody actually used them. On the Deck, the trackpads turned out to be the killer feature for strategy games, point-and-click adventures, and anything else that traditionally needed a mouse. Crusader Kings 3 on a handheld is genuinely playable, which would not be true without the trackpads.
SteamOS, Proton, and the Linux thing
The bigger bet was software. Valve shipped the Deck running SteamOS 3, which is Arch Linux underneath with KDE Plasma as the optional desktop. The default mode is "Game Mode", which is basically the same Big Picture interface from the Steam client, scaled for the Deck's screen. Click into desktop mode and you have a full Linux PC, complete with a browser, a terminal, and the ability to install Flatpaks.
The piece that made it work was Proton. It's Valve's compatibility layer that translates Windows API calls into Linux equivalents on the fly. Proton is built on top of Wine, with substantial Valve contributions to DXVK (Direct3D-to-Vulkan translation) and VKD3D (Direct3D 12-to-Vulkan translation). It is the reason a Windows game from 2018 can run on a Linux handheld in 2026 with no per-game configuration.
The compatibility numbers are remarkable. ProtonDB, a community-maintained database of game compatibility, shows that the vast majority of recent AAA titles run on the Deck with no issues. The exceptions are mostly competitive multiplayer games with kernel-level anti-cheat (Valorant, Fortnite in its current state, Call of Duty's online modes) because those anti-cheat systems specifically refuse to load on Linux.
What Valve quietly did to Linux gaming
The Steam Deck did not just sell well as a handheld. It made Linux a viable gaming platform for desktop PCs, almost as a side effect. The work Valve poured into Proton, DXVK, VKD3D, and the various Mesa graphics drivers shipped to every Linux user, not just Deck owners. Steam's Hardware Survey shows Linux's share of Steam users has roughly doubled since the Deck launched, which is not all Decks. It includes a real number of desktop Linux users who finally felt comfortable making the switch because their library would actually run.
This is the part that gets underplayed in coverage of the Deck. The hardware sold a few million units, which is fine but not earth-shattering. The software work it funded changed which operating systems are viable for gaming, period. That is the Trojan horse story.
The OLED upgrade and where it stands now
Valve released the Steam Deck OLED in late 2023, with a brighter HDR-capable display, longer battery life, faster Wi-Fi, and a slightly slimmer chassis. It was a refinement, not a sequel. Same APU, same RAM, same general performance envelope. The OLED model is the one Valve still actively sells today, alongside a base LCD model that has dropped in price.
The competition has caught up on hardware in some ways. The Asus ROG Ally, the Lenovo Legion Go, and the GPD Win 4 all match or exceed the Deck on raw specs. None of them ship with Valve's software stack, though, and that is what consistently keeps the Deck on top of usability rankings. Windows-based handhelds work, but they require fiddling. Disabling notifications, configuring power profiles, dealing with sleep that does not actually sleep. The Deck just turns on and plays games, the way a console does.
What is next
Valve has been quiet about a Steam Deck 2. CEO Gabe Newell has said in interviews that the next generation needs a "generational improvement in performance" before they will ship it, and that the current APU still has more headroom in optimization than people assume. The implication is that we are probably looking at a 2026 or 2027 release at the earliest, not 2025.
What feels more likely in the near term is the wider expansion of SteamOS to non-Valve hardware. The Lenovo Legion Go S launched with the option of SteamOS preinstalled, the first time Valve has officially shipped the OS on a third-party device. If that goes well, expect more handheld and small-form-factor PCs to ship with SteamOS as a Windows alternative.
The honest verdict
The Steam Deck was a risky launch that turned out to be the most influential PC hardware product of the decade so far. It made Linux gaming viable for normal people, it created a whole new product category, and it pressured Microsoft hard enough that there are now serious internal conversations about what Windows on a handheld should look like. Three years in, with the OLED revision out and the OS being licensed to other manufacturers, this is the moment to recognize that Valve actually pulled it off.
If you have been on the fence about getting one, and the use case is "I want to play my PC games away from my desk without buying a gaming laptop", the answer is yes. It does the thing.
