I use Nobara, moved to it from Neon myself after the debacle that was the rebase to 24.04. It’s Fedora based and you can get it with regular KDE or their own customized version. It’s Fedora with special mods made by GloriousEggroll (the dev behind Proton-GE) to improve performance mostly for gaming though the improvements can be of benefit to other applications as well. It was probably the most popular “gaming” distro until Bazzite became the hot new thing. Give it a try and see how it runs on your hardware.

“Pretty capable” will get you dunked on in the PC gaming world. For what I’ve seen PC gamers actually recommend I could buy 2-3 modern consoles.

I don’t think it will ever happen, but the way PeerTube as a whole would be able to rival YouTube is when looking at all instances as a whole, or a large number of federated instances sharing content. That distributes the content storage and bandwidth to help ease things up and expand the amount of content available/searchable on each instance. Kind of like how lemm.ee was made to help ease the load from other bigger instances of Lemmy such as lemmy.world. The closest a Fediverse platform has gotten to actually posing some real competition to a mainstream platform was Mastodon compared to Twitter/X, but even then it wasn’t just one instance but Mastodon as a whole.

That said, doesn’t Bluesky run on something like a federated model?
