Introduction

Steam’s monthly Hardware & Software Survey, published by Valve, offers a window into what operating systems, hardware, and software choices its user base is making. It has become a key barometer for understanding trends in PC gaming, especially for less dominant platforms like Linux. The newest data shows that Linux usage among Steam users has edged downward subtly. While the drop is small, it raises interesting questions about momentum, hardware preferences, and what might lie ahead for Linux gaming.

This article dives into the latest numbers, explores what may be pushing them to abandon Steam, and considers what it means for Linux users, developers, and Valve itself.

Recent Figures: What the Data Shows

• June 2025 Survey Outcome: In June, Linux’s slice of Steam’s user base stood at 2.57%, down from approximately 2.69% in May — a decrease of 0.12 percentage points.

• Year-Over-Year Comparison: Looking back to June 2024, the Linux share was around 2.08%, so even with this recent slip, there’s still an upward trend compared to a year ago.

• Distribution Among Linux Users: A significant portion of Linux gamers are using Valve’s own SteamOS Holo (currying sizable usage numbers via Steam Deck and similar devices). In June, roughly one-third of the Linux user group was on SteamOS Holo.

• Hardware Insights:

  • Among Linux users, AMD CPUs dominate: about 69% of Linux gamers use AMD in June.

  • Contrast that with the Windows-only survey, where Intel still has about 60% CPU share to AMD’s 39%.

Interpreting the Slip: What Might Be Behind the Dip

Though the drop is modest, a number of factors likely combine to produce it. Here are possible causes:

1. Statistical Noise & Normal Fluctuation Monthly survey results tend to vary a bit, especially for smaller share percentages. A 0.12% decrease could simply be part of the normal ebb and flow.

2. Sampling and Survey Methodology

   • Survey participation may shift by region, language, hardware type, or time of year. If fewer Linux users participated in a given month, the percentage would drop even if absolute numbers stayed flat.

   • Language shifts in Steam’s usage have shown up before; changes in how many users set certain settings or respond could affect results.

   • Latency or delays in uploading or processing survey data might also contribute to anomalies.
