From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Steam on Linux use in March hit an all-time high of around 5.33% marketshare. Since then it pulled back to around 4% while for September 2026 the Steam Survey results are now in and it's clocking in just above 3%.

The Steam Survey results for September that were published this evening indicate a rather steep decline of 0.85%, down to 3.05%. Meanwhile macOS is at 1.92% and Microsoft Windows at 95%.

As with most months where Steam Survey indicates an abnormally large decline for Linux use, the second stop is checking on the language use... Once again a case of a big spike in Simplified Chinese use. Steam's Survey reports a 7.42% increase in Chinese use, up to 31.39% overall of the Steam population. Usually with those large month-over-month swings where Steam China use shoots up dramatically is a boost to Windows and a detriment to Linux. Some attribute the large increases in Simplified Chinese use to being a reporting/sampling issue.

When diving into the Steam Linux data exclusively, CachyOS has spiked by another 2.65% to now account for 18.12% of the sampled Linux gaming population. That even outperforms SteamOS Holo coming in at 17.37%.

Among Linux gamers on Steam, AMD CPUs still account for the high 60 percentage space thanks to the Steam Deck and Steam Machine using AMD APUs and their open-source/Linux support being popular with enthusiasts.

Those wanting to dive in to all the Steam Survey stats for September can find the fresh data on SteamPowered.com.

I still don't get why I can't opt in to participate in the survey every month, I've only been asked twice in the last three years on Arch

[–] aim_at_me@lemmy.nz 17 points 12 hours ago (2 children)

Because thats not how good stats works. They want random samples to draw actual stats from.

Volunteering ruins the point.

They could just pull the stats from every system

privacy issue

censuses only have marginally better results than random sampling

[–] aim_at_me@lemmy.nz 4 points 11 hours ago* (last edited 11 hours ago) (1 children)

Probably. But it'd 50x the cost of the tool. And for only marginally better results.

[–] Sludge@sh.itjust.works 2 points 10 hours ago (1 children)

Would pushing a request through steam to participate in the survey realistically increase cost?

[–] aim_at_me@lemmy.nz 1 points 3 hours ago (1 children)

The notification would be negligible in cost, but the collation and processing of that collected data would not.

We're talking about ~5c worth of energy...

[–] aim_at_me@lemmy.nz 1 points 27 minutes ago* (last edited 26 minutes ago)

And, in your professional opinion, how much in compute, database, network, and storage costs? We mutli AZ, with some offsite backup or nah? We got a test version of this stack with some junk type-correct data? You 50x the dataset, you 50x all of that.

Look. I’m not saying its gonna bankrupt Valve of all companies. But its clear that people replying have 0 idea about how much hosting 4 9’s available, resilient, reliable, web tooling costs.

[–] yxc999@lemmy.ml 0 points 11 hours ago (2 children)

Yeah, you have a point, but still, twice in three years? I don't know how representative it really is, ESPECIALLY when you see 50-100% ups and downs in the Linux user base. 5 to 3 percent and back cannot be the actual stat, that has to be unreliable selection of users.

[–] aim_at_me@lemmy.nz 2 points 3 hours ago

It happens when they survey China. I don’t know why China isn’t included in the regular survey runs, but if they know the parameters of their surveying, they can make more accurate analysis of it than us.

steam has at least 130 million monthly active users

a margin of error of 1% (resulting in a range of 3–5%) is very, very good
