Fedora, it fucking slaps and worked right out of the box. I'm using it for work and play on my main rig! I dual boot for some very specific hardware things that are not normal, but other than that it's been seamless! When I booted into Windows 10 again, they auto installed copilot... Glad to be done with this crap.
In an ideal state the more flatpaks you use the more efficient it is per flatpak. If you download one flatpak you also need the runtimes for it. If you download 10 flatpaks and they all share the runtime then the cost of having the runtime isn't so high, comparatively.
But as it turns out, some flatpaks don't update in sync with others and now you have multiple runtime flatpaks. If you use Nvidia drivers now you have the Nvidia driver installed twice on your system: the main install and the flatpak version of it. Ditto for Mesa. Stupid things like that.
I still use Flatpaks, though.
Hopefully this problem goes away once NVK formally drops and people don't have to install a big huge blob on their machines anymore.
Joke's on me! I have a pre-Turing Nvidia GPU which doesn't have open source module support. What I know for sure is that I'm not buying Nvidia again.
