Valve’s Linux-based SteamOS is rapidly reshaping the landscape of PC gaming, with new data from Steam’s July 2025 Hardware & Software survey illustrating a notable shift in user preference away from Microsoft’s once-unassailable Windows 11. According to the survey, SteamOS market share surged by 0.32%—now accounting for approximately 2.89% of all Steam users—while Windows 11 suffered a 0.44% decline. This momentum underscores a broader change in platform loyalty, driven in large part by the surging popularity of devices like the Steam Deck, Lenovo Legion Go, and Asus ROG Ally, which now offer robust support for SteamOS and demonstrate a clear appetite for alternatives to Windows in the handheld gaming sector.
The dominance of Windows on gaming PCs has long seemed absolute, but Valve’s introduction of the Steam Deck in 2022 marked a pivotal moment. The handheld device, preloaded with SteamOS, showcased the OS’s capabilities in providing a console-like experience within the open ecosystem of PC gaming. SteamOS offered immediate advantages for gamers seeking both performance and flexibility, igniting renewed interest in Linux as a credible gaming platform.
Handheld gaming devices have since become a powerful growth engine, not only for Valve’s hardware but for SteamOS adoption. As the handheld market matures, established names like Lenovo and Asus have entered the fray with Windows-based handhelds—but crucially, they also support SteamOS, broadening its reach and reinforcing an ecosystem in which Windows is no longer the sole superpower.
Lenovo and Asus have followed with their own handhelds—the Legion Go and ROG Ally—that embrace the flexibility offered by SteamOS. This hardware-agnostic approach accelerates adoption and encourages developers to consider Linux a first-class target for releases, not merely an afterthought.
Microsoft is doubling down on its commitment to gamers with the rollout of a revamped Xbox PC app. This critical update brings a full-screen experience aimed squarely at handheld gaming devices, including the ROG Xbox Ally. The new app promises easier access to PC Game Pass, improved navigation, and tighter integration with Windows gaming features—a direct countermove to SteamOS’s streamlined interface.
Microsoft is also expanding support for gaming-optimized drivers, DirectStorage for faster game loading, and Auto HDR for enhanced visuals. These improvements are designed to shore up Windows’s position as a best-in-class gaming platform, particularly as competitive pressure intensifies.
The ecosystem built around SteamOS also encourages experimentation. With features like sandboxed game installs, robust community mods, and full access to the Linux desktop, users can customize their experience without fear of system rot or malware endemic to less controlled ecosystems.
As Microsoft accelerates its own user-centric updates in response, the stage is set for a new era of platform competition—one that will benefit gamers through better tools, more choices, and deepened innovation. For millions of players seeking an optimized, gaming-first experience, SteamOS now stands as a compelling alternative—and its best days may yet lie ahead.

SteamOS: Market Growth and Key Drivers
Expanding User Base
SteamOS’s current share—nearly 2.89% of the total Steam user base, representing roughly four million gamers—would have been inconceivable only a few years ago, when Linux’s gaming market hovered below the 1% mark. The latest survey data shows not only steady growth but a clear acceleration associated with the handheld gaming boom. While Windows still holds a commanding lead, every tenth of a percent now represents hundreds of thousands of players making the shift.The Power of Handhelds
The success of the Steam Deck cannot be overstated. Its seamless integration of hardware and software, optimized for gaming on the go, demonstrates the unique appeal of a Linux-based system purpose-built for gamers. Since its launch, Valve has poured resources into refining compatibility layers such as Proton, making it possible to play a vast majority of Windows games on SteamOS with little to no compromise.Lenovo and Asus have followed with their own handhelds—the Legion Go and ROG Ally—that embrace the flexibility offered by SteamOS. This hardware-agnostic approach accelerates adoption and encourages developers to consider Linux a first-class target for releases, not merely an afterthought.
Why Gamers Are Switching: Key Advantages of SteamOS
Performance-First Philosophy
At its core, SteamOS is engineered for gaming excellence. Stripped of legacy overheads that can drag down performance on traditional Windows systems, SteamOS provides a lean, purpose-driven environment. Gamers routinely report smoother frame rates and more consistent performance, especially on modest or handheld hardware where system resources are at a premium.Accessibility and Customization
Another pillar of SteamOS’s appeal lies in its accessibility. Valve has invested heavily in ensuring that SteamOS remains user-friendly for both newcomers and seasoned tinkerers. The availability of tools like Decky Loader enhances customization, allowing users to tailor everything from power profiles to graphical settings without the bloat or restriction often found in proprietary systems.- Quick access to community plug-ins and enhancements
- Streamlined update process, avoiding forced reboots
- Enhanced support for controllers and touch interfaces
Gaming-Focused Features
Unlike multi-purpose operating systems, SteamOS delivers a tailored experience. Features such as a unified gaming mode, integrated performance overlays, and automatic compatibility fixes cater directly to the needs of gamers. The centralized Steam interface also removes much of the friction in game management, system updates, and hardware configuration.- One-click game library access optimized for handheld use
- Integrated Proton for seamless Windows game compatibility
- Support for dynamic scaling and profile-based settings
Windows 11 Fights Back: Microsoft’s Response
Major Updates on the Horizon
Despite the headwinds, Windows 11 remains the default choice for most PC gamers. Microsoft’s dominance has been maintained through sheer software compatibility and strong hardware partnerships. However, the recent downturn in market share—combined with user migration to SteamOS—has prompted swift action.Microsoft is doubling down on its commitment to gamers with the rollout of a revamped Xbox PC app. This critical update brings a full-screen experience aimed squarely at handheld gaming devices, including the ROG Xbox Ally. The new app promises easier access to PC Game Pass, improved navigation, and tighter integration with Windows gaming features—a direct countermove to SteamOS’s streamlined interface.
Hardware Partnerships and Ecosystem Improvements
Beyond software updates, Microsoft continues to fortify its ecosystem through strategic partnerships with manufacturers. Devices like the Asus ROG Ally ship with deep integration of Xbox services, ensuring a familiar environment for Windows gamers making the jump to handhelds.Microsoft is also expanding support for gaming-optimized drivers, DirectStorage for faster game loading, and Auto HDR for enhanced visuals. These improvements are designed to shore up Windows’s position as a best-in-class gaming platform, particularly as competitive pressure intensifies.
Critical Analysis: SteamOS Strengths and Potential Risks
Notable Strengths
The momentum driving SteamOS is anchored in several indisputable strengths:- Optimized performance on constrained hardware and handhelds
- Rapid compatibility improvements via open-source updates (e.g., Proton, Mesa drivers)
- Flexible customization for community-driven innovation
- Robust security and privacy with fewer pre-installed or unwanted services
Potential Risks and Limitations
It would be misleading, however, to overlook ongoing challenges:- Game compatibility gaps persist—while Proton is a marvel, a minority of recent AAA titles with aggressive anti-cheat or DRM still struggle to run smoothly.
- Developer support is uneven, particularly outside of the Steam ecosystem. While indie and mid-tier studios are increasingly Linux-aware, full platform parity remains an aspirational goal.
- Peripheral and third-party software limitations may frustrate users accustomed to Windows-only tools, especially when handling mods, streaming, or niche accessories.
- Learning curve for power users and those migrating from Windows remains nontrivial, though this is less acute for dedicated handheld devices.
