Linux gaming surpasses 5% market share among Steam users, fueled by SteamOS, Steam Deck, and increased compatibility with Proton.
For the first time in the history of the Steam Hardware & Software Survey, Windows has dropped below 93% among gamers, while Linux gaming has crossed the 5% threshold, signaling a shift in the gaming ecosystem. These results reflect broader trends in gaming hardware, operating system adoption, and the growing influence of Valve’s SteamOS, particularly with the rise of the Steam Deck and its ecosystem of SteamOS-based gaming devices.
Windows Market Share Decline
In March 2026, Windows 10 saw its usage among Steam gamers drop by nearly 15%, a steep decline compared to previous months. Meanwhile, Windows 11 saw a modest uptick of only 10.6%, suggesting that the decline in Windows 10 usage is not being fully offset by adoption of Microsoft’s latest OS.
The overall Windows market share among gamers now stands below 93%, a notable milestone considering the long-standing dominance of Microsoft’s OS in the PC gaming world. While Windows remains the majority platform, the decline indicates a diversification of operating systems in the gaming community, influenced both by alternative OS options and changes in hardware adoption.
Linux Gains Ground
Linux’s growth in the gaming sector has been particularly significant, with its market share increasing by more than 3.1% to reach 5.3% among Steam users. This represents a new high for Linux gaming and reflects the impact of Valve’s ecosystem, particularly SteamOS, which has been optimized for gaming performance.
Among Linux gamers, SteamOS Holo 64-bit remains the most popular distribution, accounting for 25% of Linux-based gamers. This is unsurprising given the success of the Steam Deck, which runs on SteamOS, and the growing trend toward dedicated Linux gaming hardware.
Other popular Linux distributions include:
- Arch Linux – 8.8% of Linux gamers
- Linux Mint – 6.9% of Linux gamers
There are also a few distributions listed in the survey without proper names, such as “0 64 bit” and “64 bit.” These could potentially be experimental or upcoming versions of SteamOS, or even distributions like Fedora that are not fully specified in the survey.
macOS Also Sees Modest Growth
In addition to Linux, macOS has seen a slight increase in market share, rising by 1.2% across various versions. While macOS remains a minority platform for gaming, this growth suggests that some gamers are diversifying their OS usage, possibly influenced by cross-platform games and the increasing power of Apple’s hardware for gaming applications.
SteamOS and Steam Machines: Driving Linux Adoption
Valve’s continued investment in SteamOS and Steam Deck hardware has been a major factor in Linux’s growth. The Steam Deck’s success has not only introduced new users to Linux gaming but has also highlighted the viability of Linux as a competitive gaming platform.
The introduction of upcoming Steam Machines and further iterations of SteamOS is likely to accelerate this trend, as more players gain access to Linux-based gaming hardware optimized for performance, compatibility, and a wide range of titles.
SteamOS has been designed with gaming in mind, supporting Proton, Valve’s compatibility layer that allows Windows games to run on Linux without major performance compromises. This has made Linux an increasingly attractive option for gamers who were previously tied to Windows due to game compatibility concerns.
Implications for Microsoft
The decline in Windows’ market share among Steam gamers, even as small as it may seem, represents a crack in Microsoft’s long-standing dominance of PC gaming. Microsoft has been making repeated promises to enhance Windows specifically for gaming, including improvements to DirectX, better optimization, and system-level performance enhancements.
Despite these efforts, the rise of Linux gaming and the increasing adoption of alternative OS platforms indicate that gamers are exploring other options that may offer better performance, lower costs, or a more streamlined gaming experience.
The Future of Gaming OS Diversity
While Windows remains the dominant platform, the growth of Linux and modest gains by macOS suggest a slowly diversifying OS landscape in PC gaming. Key factors influencing this shift include:
- Dedicated Linux Gaming Hardware – Devices like the Steam Deck make Linux accessible and performance-optimized for gamers.
- Compatibility Layers – Tools such as Proton enable Windows games to run seamlessly on Linux, removing a major barrier to adoption.
- Open-Source Flexibility – Linux’s open-source nature allows for customizations and optimizations that appeal to advanced users and developers.
- Community Growth – Linux gaming communities continue to expand, providing resources, guides, and support for newcomers.
If this trend continues, we could see Linux surpassing 10% of the gaming market in the next few years, particularly as Valve and other companies optimize software and hardware for Linux-based gaming environments.
Conclusion
The Steam Hardware survey for March 2026 shows a notable shift in gaming OS preferences. Windows use among gamers has dropped below 93%, Linux has reached a historic 5.3%, and macOS has seen modest gains. The rise of SteamOS and the Steam Deck has been a major driver of Linux adoption, highlighting that gamers are willing to explore alternatives to Windows when performance and compatibility are ensured.
Microsoft faces increasing pressure to maintain its dominance in PC gaming as the ecosystem diversifies. Meanwhile, Linux gaming is proving itself not just viable but increasingly mainstream, thanks to Valve’s initiatives and the broader support for gaming on open-source platforms.
This trend signals a slowly but steadily diversifying future for gaming operating systems, one where Linux will play an increasingly prominent role in the years to come.
