Overall, 3% might not seem like much to some, but again - that trend is very clear and equates to millions of people. The last time Valve officially gave a proper monthly active user count was in 2022, and we know Steam has grown a lot since then, but even going by that original number would put monthly active Linux users at well over 4 million. Sadly, Valve have not given out a more recent monthly active user number but it's likely a few million higher, especially with the Steam Deck selling millions.
