You say it’s because of configs etc., i.e. problems caused by the user. That is a serious difference. You should also narrow it down to SteamOS, Garuda, Bazzite, CachyOS or one of the other distributions designed for gaming. After all, these are also experiencing the most growth in gaming from people leaving Windows behind.

Windows and stable? So blue screens during OS installation are stable? Windows didn’t catch on because it was stable. It stole the most important thing and then the dirty gag contracts where Intel and Nvidia were also involved. That’s the only reason why this trickery has prevailed. Windows is and always has been rubbish, but MS knew how to damage competitors and secure a monopoly position. Windows and stable are a joke.

Every OS was programmed by humans and contains errors. This does not apply to just one OS or the other. In addition, faulty software also runs on faulty hardware. From this point of view, stable is no longer possible with today’s CPUs, even if you counteract this via microcode.
