I have zero interest in spending this beautiful Friday morning arguing, so I'm not going to, but if you would like some reading recommendations to understand my political positions on these sorts of things, let me know and I'd be happy to provide them.
I play on a proper PC, not a steam deck. Of course there are going to be performance compromises on a portable device with an APU; that's got nothing to do with the OS.
I exclusively run Linux and I play modern games all the time without issues. You just click "install" on Steam and it works 99.9% of the time; I dont even look up the game to check if it works anymore. Also, have a look at some comparisons on YouTube — some games actually run faster on Linux because there's less bloat in the OS.
What distro are you on? Some don't install all available KIO workers and you'll have to install them yourself.
Is this something that is likely to improve going forward?
Like any FLOSS project, things tend to happen when programmers decide to solve a problem for themselves. If you don't the the skills to do this, you could always bring it up on the KDE forum under the "brainstorming" category, submit a feature request on the KDE bug tracker, or sponsor a developer to perform the work.
Well that's just it; Endeavour is not a beginner distro. It's not designed to be. Endeavour is Arch with a graphical installer and some modest quality of life improvements for users who are otherwise willing to trawl through the Arch wiki for answers. The welcome app really just seems to be there so that you don't have to memorize all the commands or set up aliases, etc, if you don't want to.
So when you ask "am I supposed to X," the answer is that there really isn't a set-in-stone workflow to accomplish anything on EOS or Arch; what you're supposed to do is read the manual, so to speak, and decide for yourself how you want to go about things.
Unlike some other Arch based distros like BlendOS and Manjaro, Endeavour is still very much a DIY distro.
Don’t use GUI package managers, but here, have some GUI package managers.
What GUI package managers are you referring to? EOS doesn't supply any.
AFAICT they made something more confusing than Arch, not less.
If I'm not mistaken, this is all stuff you should also be doing on Arch. The single difference is that EOS provides a button in their "Welcome" app that will helpfully run a command for you in a terminal for some of these tasks.
I am, yes.
