Valve’s SteamOS is steadily gaining users, as more gamers move away from Microsoft’s Windows 11. Recent data from Steam’s July 2025 Hardware & Software survey shows SteamOS market share increased by 0.32%, while Windows 11’s share fell by 0.44%. This shift suggests that many gamers prefer SteamOS, especially on handheld devices.
Linux-based SteamOS now holds about 2.89% of the Steam user base, roughly four million players out of 132 million. This growth is likely linked to the rising popularity of handheld gaming since Valve launched the Steam Deck in 2022. Devices like the Lenovo Legion Go and Asus ROG Ally also support SteamOS, increasing its reach beyond Valve’s own hardware.
Though Windows 11 remains dominant, SteamOS is praised for better game performance, accessibility, and gaming-focused features. Users appreciate the easy customization and improved graphics tools offered by SteamOS, such as Decky Loader, which are especially useful for handheld gaming.
Microsoft is responding with major updates to Windows 11, including a new full-screen Xbox PC app experience aimed at gamers. This will debut on devices like the ROG Xbox Ally and promises to improve gaming on Windows handhelds.
However, many gamers remain loyal to SteamOS, saying it already feels more optimized for gaming on handheld devices. While Microsoft’s new features are welcome, the current momentum suggests SteamOS may continue to grow faster in the gaming community.
