On KDE there’s System Monitor, which you can customize to show graphs for CPU usage and temp, among other things, and GPU usage and temp too.

For in-game monitoring there’s Mangohud, also very customizable on what you can show in the overlay

I don’t know if you’ve tried it yet, but setting the “Haptic Touch” option to “Fast” gets you a bit closer to what you could do with 3D touch.

It’s under Accessibility -> Touch -> Haptic Touch

Personally I like it better vs the default setting.

I copy everything in my home folder and paste it all in the new installation. Works well if I stick with the same desktop environment.

I think it’s worth noting that Tumbleweed also has the Mesa/codecs situation, where if you want the codecs you have to enable the Packman repo and install mesa from there, and when there’s an update for mesa you have to wait for the update on Packman repo, otherwise you get some conflicts when trying to update. Though packman usually updates quick enough so it’s usually not an issue but it can be a bit weird the first time you see it.

Aside from that yeah, Tumbleweed is great. Though i’m currently running Fedora Kinoite and overall I’ve been happy with it, but I would probably go back to Tumbleweed if something were to happen.
