Personally I haven’t. While Linux is imperfect, choosing the right distro makes the rest of the experience straightforward. And with it’s whole complexity, I find Linux more user friendly than Windows. Even driver issues, broken shadow file ownership and KDE specifics only made me more confident about my choice to use Linux after I solved everything.
Valve said they’re actively working with nvidia to support their gpus. While I’m sure valve hardware will always be the primary concern, they seem to actively pursue the goal of SteamOS being more widely compatible.
Sure, but “works with nVidia” isn’t the same as “works with everything,” since there’s a lot of other hardware to consider, though I’d imagine the latter case would be mostly easy for an end user to work around.
That’s all I’m really pointing out with that part, and if I’m wrong, then it’s only good news for the rest of us.
But the benefit of SteamOS is going to be marginal at best since lots of distros are already highly capable for gaming. Waiting isn’t going to bring with it some magical improvements that makes it the default choice over CachyOS, Bazzite, PikaOS, etc.
