Linux Gaming Adoption Rises to 3% on Steam

07 Nov 2025

Linux gaming has reached a new milestone, capturing 3.05% of the user base on Steam according to the latest Steam Hardware Survey data. This marks a significant rise from last year’s approximate 2%, highlighting a shift in gaming operating system preferences.

SteamOS Growth and Adoption

SteamOS, the Linux-based operating system developed by Valve, now constitutes about 27% of all Linux installations on Steam. This progress is largely driven by the popularity of the Steam Deck and similar devices, which introduce more users to the Linux ecosystem without requiring an explicit choice for Linux.

However, the reliance of many competitive multiplayer games on kernel-level anti-cheat systems, which are natively supported on Windows, remains a challenge for Linux adoption.

Proton’s Role in Expanding Game Compatibility

Proton has made a substantial impact by enabling over 90% of Windows games to be run on Linux. While not every game operates flawlessly, the increased compatibility illustrates significant strides in Linux gaming capabilities.

This development suggests that Linux may become a viable alternative for an increasing number of gamers, especially those frustrated by certain Windows decisions and seeking alternatives.

Market Influence and Future Prospects

While Windows still dominates with nearly 95% of the Steam platform share, the growing interest in Linux gaming indicates a gradual shift. Current user frustrations with Windows, coupled with the rising popularity of handheld gaming devices, could potentially increase Linux's presence in the market.

Although 3% does not yet threaten Windows’ supremacy, the continued development and acceptance of Linux-based systems suggest this trend may become significant over time.
