Steam On Linux Gaming Finally Cracks 3% For October 2025

Steam on Linux use has hit an all-time high! With the Steam Survey results for October 2025 coming out this evening, Steam on Linux has finally cracked the 3% threshold! A few months back Steam on Linux was close to 3% before stumbling a bit but now it's above that elusive threshold. The only time Steam on Linux use was close to the 3% mark was when Steam on Linux initially debuted a decade ago and at that time the overall Steam user-base was much smaller than it is today. Long story short, thanks to the ongoing success of Valve's Steam Deck and other handhelds plus Steam Play (Proton) working out so well, these October numbers are the best yet.

The October 2025 numbers just published minutes ago put a hearty 0.41% increase to Linux for landing its overall marketshare at 3.05%. Windows meanwhile was at 94.84% (falling below 95% for the first time in a while) and macOS at 2.11%. For comparison, in October 2024 Steam on Linux was at 2.00%.

The Linux-specific data shows SteamOS commanding around 27% of all the Linux installs at large. SteamOS most notably being on the Steam Deck hardware.

The Linux-specific data shows Intel gaining 1% CPU marketshare for 32.89% against AMD"s 67.1% for October. Meanwhile for the WIndows data, Intel has 57.8% to AMD at 42%.

These Steam Survey numbers for Linux are the best yet with cracking the seemingly elusive 3% threshold and the overall Steam user base continuing to grow nicely.
