It’s a combination between KDE 6 and Wayland, which required support in the Nvidia drivers. I remember running Nvidia on KDE 5 and had zero issues compared to now, but we’ll just have to wait. Some issues are just configuration changes that needs to be implemented by the distro mantainers (literally a one line fix on a conf file which was communicated by KDE but not picked up)
It’s as easy to install as any other Linux distro now. Then you have to learn all the configurations of course…
