Important to note that the results are a bit weird though for the last couple months.

In December, after Win10 EoL, linux achieved a record 3.58% of Steam users. However there was a massive drop in February, down to 2.23% of users on Linux. This was accompanied by a massive spike in Chinese steam accounts (english users dropped from 36% of user accounts in the survey to 22%, while Chinese user accounts jumped from 24% of users to 54% of users). I’m guessing it was a bunch of chinese bot accounts. (edit: as pointed out in the comments, this was probably due to chinese new year. Lots of chinese people hitting gaming cafes).

Now for March, Linux jumped back from 2.23% of users to 5.33% of steam users surveyed. Leading the charge are two unidentified distros 0 64-bit (+17.6%) and 64-bit (+8%).

The unknown distros being responsible for the massive gain is very suspicious, so we’ll have to see if that part ends up being correct or not. On the other hand, the surge of chinese accounts that seemingly pushed down linux’s percentages last month are now gone, with chinese accounts dropping from 54% of users to 23%.

So ultimately we’ll need to wait and see if valve clarifies what “0 64-bit linux” and “64-bit linux” are, or wait until next month to see how things change.
