Note, the source will change every month. That’s why I made a screenshot, so the discussion in this thread makes sense in the future. Source: https://store.steampowered.com/hwsurvey/?platform=linux
Linux Mint 22.2 64 bit got +3.34% from previously 0%, while Linux Mint 22.1 64 bit lost -2.71%. So the rest of the 0.65% are either new users or upgraders from even older Linux Mint versions. Whatever the reason is, these two entries should have been a single one as Linux Mint 22 with 8.84%.
Also what is the category “Other”? It’s almost 20% big, so this is not something to wave over. Bazzite got a good start, hopefully it will grow further. I’m surprised that CachyOS is this popular, much more than Ubuntu and Bazzite.
For me Steam never picks up the discrete GPU and always wants to report the integrated one. Might be relevant for you if you intend to do anything with Steam’s hardware survey data.
