I think we can now firmly say that we are the 1%? Another month is down as so the latest Steam Hardware Survey numbers are out and it continues being very positive for Linux gaming.
As we show on our dedicated Steam Tracker, we've now seen the Linux user share on Steam remain above 1% for 5 months and we've seen 7 months of continuous growth.
Valve usually does an announcement of user numbers early each year, so hopefully in 2022 they can give us an updated monthly active user count to see where we are compared to before. Going by their last numbers, there would be approximately 1,396,640 monthly active Linux users on Steam.
We're still a while away from seeing how the Steam Deck will affect this, if at all, as it depends on how Valve will be tracking the number of SteamOS 3 devices. With their original SteamOS 2 that was for Steam Machines, it wasn't properly included as Big Picture Mode does not get the survey. This time they're redesigning the UI, so hopefully it will be included or they might just show how many people have one like they do for VR kits.
We do also know that SteamOS 3 will be released as a standalone operating system, as confirmed by Valve, so we may even see more devices and people using it.
