According to these new numbers from Valve, the Linux customer base is up to 1.96%, or a 0.52% jump over June! That’s a huge jump with normally just moving 0.1% or so in either direction most months… It’s also near an all-time high on a percentage basis going back to the early days of Steam on Linux when it had around a 2% marketshare but at that time the Steam customer size in absolute numbers was much smaller a decade ago than it is now. So if the percentage numbers are accurate, this is likely the largest in absolute terms that the Linux gaming marketshare has ever been.

There will not be the equivalent compatibility at first. But there will be enough compatibility for most users to not care about it anymore. The equivalent compatibility will only exist once literally every hardware and software manufacturer supports Linux on their own as first-class citizen. And they will only do that once Linux has signifikant desktop marketshare. But it doesn’t matter as long as most stuff still runs no matter what. Which is currently the case. And it’s also gotten easy.
