Comparing to Windows 10, Bluefin runs extremely slow. The whole experience is sluggish. CPU Usage is always above 70%. Same report here.
I don’t think it’s GNOME issue, because no such issue is present on Debian + GNOME, even if it’s not linux new user friendly.
Haven’t really noticed any difference when compared to my other machine that is still on Arch+Gnome setup (which I don’t really use).
Maybe check something like htop what is actually using the CPU if its 100% all the time. It might be just the system upgrade process that runs in the backgound once a day.
