Free Windows 10 support ended for most people this past month, and the trend line of Linux usage has been quite clear leading up to this, as people prepared for the inevitable. An increase in Linux usage is also correlated to a drop in Chinese players, which did happen this month a little bit, but Linux usage is also trending up when filtering for English only. It’s worth noting that for all the official support Macs ever saw in gaming, they never represented anything better than about 5% of the market.
Haven’t checked the news itself, but been following the hardware surveys from Valve for some years now, and on average, Linux is on a slow but constant growth. Also, been checking US’s official analytics site every now and then for some months now, and there, Linux oscilates between 3 and 6% of users per system.
