Steam On Linux Gaming Finally Cracks 3% For October 2025 - Phoronix
For the first time ever, Linux surpassed 3% marketshare on the Steam Hardware Survey at a 3.05% clip. At the same point last year, Linux was at 2% marketshare and the year before that, at 1.39%. If you are to look at marketshare among English language users only, Linux makes up 6.61%, also an all-time high.
	When analyzing the Linux-specific data, SteamOS makes up 27.18% of all installs which was down by 0.47 points from the previous month. This would mean while the Steam Deck is helping Linux grow, the traditional Linux desktop is also pulling its weight.
There is still a long ways to before Linux becomes "too big to ignore". Multiplayer games will forever be a nagging issue because that's up to the developers to enable anti-cheat for Linux. The Nvidia GPU experience on Linux is still far from hassle-free, but the NVK driver is making progress such as enabling DLSS support.
