Actual Linux Market Share could be Higher
Steam doesn’t agree. It’s a 2% there. I don’t know which site would report more than 5% market share for linux.
I would assume Steam to be lower because gaming was one of the major roadblocks for gaming until recently, and many gamers are still scared of switching over. It also assumes no dual booting and whatever they ran the check on is the registered OS. This would register both potentially.
Team’s data is also useful, but it’s different data.
I dual boot. I use Linux most of the time for everything, but I switch to Windows whenever I want to play on Steam. I just don’t have the time to bother with abstractions layers, drivers and whatnot, even if I read that Steam makes it easy to run Windows games on Linux now.
Have you tried it yet? Try installing Proton on your Linux install and pointing Steam to your existing folder that you use on Windows. It should be able to just boot them up like that without an issue.
