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.
