We know SteamOS as the tipping point that brought Linux gaming the unprecedented attention it enjoys today. Out of the 5% Linux gamers, 1/4th are on SteamOS, and a large portion of them run it on the category-defining Steam Deck. Valve's iconic PC gaming handheld was the first real proof of concept for Linux gaming on a wildly popular device, not just on a handful of desktops and laptops. SteamOS was the reason the Linux backbone disappeared, allowing gamers to accept it as a long-term option.

While Proton, Vulkan, and Mesa finally cracked widespread game compatibility, high performance, and seamless driver support, respectively, the Steam Deck became the showcase to bring this modern Linux avatar to the masses. The Steam Deck's hardware was modest for valid reasons, but that has opened the door for other manufacturers to showcase what SteamOS can do when allowed to stretch its wings. Valve's modern SteamOS iteration now supports every major AMD handheld, making gamers only more desperate to experience it on the next-gen Steam Deck.

The Steam Deck was what SteamOS was waiting for

SteamOS became what it was always intended to be

Valve's ambitions to make SteamOS a household name started long before the Steam Deck was ever a thing. The original Steam Machines in 2013 ran SteamOS 1.0 and 2.0, which were Debian-based, and a far cry from the Arch-based SteamOS 3.x of today. With limited game support, inferior performance, and a lack of a seamless ecosystem, these Steam Machines and the earliest SteamOS versions silently fizzled away.

In 2022, Valve came back with a resurgent SteamOS on a device that no one was expecting. Valve's industry-altering handheld, the Steam Deck, proved that Linux gaming didn't have to be a chore anymore. A version of SteamOS that enabled excellent performance and battery efficiency proved that gamers didn't care what OS their device was running as long as it did its job properly. The tight integration between the hardware and software allowed for a degree of standardization that was never seen on Linux before.

Proton, Vulkan, and Mesa existed before the Steam Deck, but the new SteamOS version on the Deck was the push developers needed to commit to native Linux ports. Proton was responsible for translating Windows games to Linux, but Vulkan was what made it possible without running into terrible performance. The consequent surge in development of Mesa drivers benefited not just SteamOS, but the entire Linux gaming ecosystem.

But other handhelds proved that SteamOS can fly higher

It's not even a contest

Steam Deck's hardware was always going to be its weakest link. Valve wasn't aiming for the sky; it wanted to launch a handheld delivering a consistent, enjoyable experience at a great price point. The custom AMD Zen 2 APU with RDNA 2 graphics and the 7-inch 800p 60Hz display were more than enough for a portable SteamOS experience for the vast majority of gamers. The Steam Deck OLED bumped that to 90Hz, but the rest of the internals were nearly identical. It was clear that faster handhelds from other manufacturers would soon surpass the Steam Deck's capabilities. Today, competitors like the ROG Ally X, Legion Go 2, and MSI Claw A8 use AMD's latest Ryzen Z2 Extreme chips, powered by Zen 5 and RDNA 3.5 cores, leaving the Steam Deck's modest hardware far behind.

For the longest time, though, the competition was running Windows, an OS that wasn't really built for a touchscreen handheld form factor. The hardware chops were there, but the software was keeping it from achieving its potential. The Steam Deck, despite being "outdated," felt natural to use, thanks to the console-like experience offered by SteamOS. It wasn't too long before people started experimenting with SteamOS on handhelds that weren't the Steam Deck. After multiple pre-release builds, Valve eventually released Steam OS 3.9 that supported virtually every AMD handheld. The Lenovo Legion Go S in 2025 became the first third-party handheld to officially support SteamOS, finally expanding Valve's ecosystem beyond the Steam Deck.

SteamOS was a lean, intuitive, and highly flexible environment that got a shot in the arm when the shackles of the Steam Deck were removed. Handhelds are constantly bringing faster chips, more RAM, larger screens, higher refresh rates, and bigger batteries than the Steam Deck. The perfect marriage of modern hardware and the ideal handheld OS has finally been achieved. The Lenovo Legion Go S feels like a completely different device when running Windows 11 and SteamOS, delivering considerably better performance on the latter. You can also see this in action when switching from Windows 11 to SteamOS on the ROG Ally X — the latter delivers anywhere from 10% to 33% better performance. The Steam Deck holding back the SteamOS is not a revelation in 2026. Other handhelds were always going to surpass it once the kinks were ironed out. However, it also hints at what the Steam Deck 2 could do with SteamOS.

Valve is "hard at work" on the Steam Deck 2, readying the next frontier

Valve leads the way

We always knew the Steam Deck 2 would eventually be real, but Valve doesn't just want to launch a successor for the sake of it. The company has repeatedly said that the next-gen Steam Deck 2 would not be a minor refresh. In a recent IGN interview, Valve programmer Pierre-Loup Griffais said that the company is working hard on the Steam Deck 2, and the Steam Machine, Steam Controller, and Steam Frame are directly influencing the development of the next-gen handheld. Last year, Griffais had also said that Valve wasn't interested in a 20%, 30%, or even 50% performance jump. These comments clearly show that Valve is waiting for a chip that doesn't exist yet.

The Steam Deck 2 will certainly be a massive leap over the existing Decks, and will most likely catapult SteamOS, and Linux in general, to a whole new tier of popularity and relevance. What's also clear is that other manufacturers will not wait before launching Steam Deck 2 competitors; we might see them surpass Valve's next-gen handheld within six months or a year after its launch. The interesting thing is that Valve probably doesn't care. After all, it's a software company more than a hardware company. The Steam Deck is just one of the many weapons in its arsenal to bring SteamOS to as many devices as possible. And the Steam Deck 2 is just the next milestone in that journey.

The handheld industry will inevitably improve SteamOS beyond whatever the Steam Deck 2 brings to the table. Valve will showcase the blueprint for the next era of Linux gaming with the Steam Deck 2, and the competition will refine it with more powerful hardware. SteamOS' market share will grow, more gamers will open up to Linux on desktops, and we'll once again implore Valve with "Mahdi, what do you foresee for us?"

The Steam Deck walked so others could run

Valve knew it had a winner on its hands with the Steam Deck. It knew the power of the renewed SteamOS and the ease of use of the Deck's form factor. Other handhelds may have improved on the formula, but it only clicked for them when they embraced SteamOS instead of Windows. The Steam Deck 2 will once again show the industry how it's done, probably hitting the performance, pricing, and usability trifecta again. Other handhelds will then further the dominance of SteamOS.
