OK been running the 04 13 for a couple of days with everything I use installed, fully tweaked to my liking and as the saying goes it’s as smooth as butter. I couldn’t be happier about how well pretty much everything is running and behaving. There are a couple of changes that the KDE devs made that weren’t necessary or simply should of been added as options to other settings, but for now I can live with them. I’ve made personal adjustments to deal with them. Overall the responsiveness and smoothness of the OS is simply fantastic. If the final release is like this peeps are going to be very happy.
