RTX 4070 - kernel 6.9.0 - 2 monitors
I have to set NVreg_EnableGpuFirmware=0 otherwise KDE 6 is unusable.
I also noticed that logging into KDE (X11 session) seems to take longer now than with the previous drivers.
UPDATE: Something is still very wonky, everything seems delayed, like changing desktop display settings takes longer than usual. And if the KDE screen lock kicks in, it takes some time for it to show the Password dialog.
UPDATE 2:
wayland seems to work better than X11, I also see an improvement there with explicit sync patches.
UPDATE 3:
The x11 issues seems to be a KDE hiccup, it decided to corrupt some config files. It works better now.
