Five percent. That's where Linux stands on Steam right now, and depending on who you ask, it's either a sign of real momentum or proof that the so-called Big Switch is still mostly a Reddit fantasy.
A Reddit post from user xVarrick on r/linux_gaming laid it out clearly, comparing Steam Hardware & Software Survey results from March 2024, March 2025, and March 2026 in a single bar graph. The numbers tell a story that's part encouraging for Linux fans, part sobering.

What the three-year snapshot actually shows
As of March 2026, Windows still commands 92.33% of Steam's user base. That number did shrink by 3.77% between March 2025 and March 2026, which is notable, but it's not exactly a mass exodus. macOS picked up 0.77% of that movement. Linux took the bigger slice, jumping 3% to land at 5.33% total.
Here's the thing: in raw terms, 5% of Steam's concurrent user base is not a small number. Steam's all-time peak of 42,686,616 concurrent users means roughly 2.1 million people are gaming on Linux right now. That's a real audience, not a rounding error. According to Steam's own survey data, SteamOS Holo 64-bit sits at the top of the Linux distro breakdown, which lines up with the continued popularity of the Steam Deck.
The Windows 10 holdout problem
The more interesting wrinkle in the data is what's happening inside the Windows camp. As of March 2026, 27.03% of Windows users on Steam are still running Windows 10, even though Microsoft ended support for it in October of last year. That group shrank by a massive 14.57% in a single month, which suggests many finally made a move.
Most of them went to Windows 11, which saw a 13.09% uptick. But Windows 11's strict hardware requirements mean a chunk of older machines simply can't upgrade through official channels without workarounds like Flyby 11 or Rufus. For those users, the choice is either jumping through hoops to stay on Windows or finally giving Linux a serious look.
For context, Windows 11 only overtook Windows 10 in Steam's user count in October 2024, nearly three years after launch. That slow adoption curve says a lot about how reluctant the gaming community is to change operating systems, even when pushed.

Why Linux is better positioned than ever
The gaming case for Linux has genuinely strengthened. Dedicated distros like Bazzite have made the setup process far less intimidating, and Proton compatibility has expanded to the point where most Steam titles run without major issues. The Steam Deck's success also normalized SteamOS for a generation of players who might never have touched Linux otherwise.
What most players miss is that the growth isn't happening because Linux suddenly became perfect. It's happening because Windows gave people reasons to leave. Between aggressive AI feature pushes, hardware requirement walls, and ongoing questions about Microsoft's direction, the friction of switching feels lower than it used to.
Linux gaming compatibility has expanded significantly through Valve's Proton layer, but some titles with aggressive anti-cheat systems still don't run on Linux. Check ProtonDB before committing to a full switch if competitive multiplayer is your priority.
The gap that still needs closing
The key here is understanding what 5.33% actually represents in context. Linux has been the "about to break through" platform for years, and the data suggests growth is real but gradual. A 3% year-over-year jump is the best movement the platform has seen in gaming, but closing the gap on Windows from 92% to anything approaching parity would require a shift in scale that isn't visible in the current data.
For players sitting on aging Windows 10 hardware with no clean upgrade path, the next few months could produce another bump in Linux numbers as Microsoft's extended support window continues to narrow. Whether that translates to sustained growth or a one-time spike is the question worth watching. You'll want to keep an eye on the April and May Steam survey results for early signals.
