I get good performance with Nvidia 560 on both kernel 6.11.0 and 6.8.0.
This was a fresh install of Oracular, using a Pascal card.

  [regression] Very poor performance in Nvidia Wayland sessions

Bug description:
  I've just tried the Nvidia-560 driver for the first time and am seeing
  very poor performance in Wayland sessions. Just tapping the Super key
  I can see animations stuttering.

  In 'NVIDIA Settings' it looks like the reason might be a lack of power
  profiles ("Performance Levels"). Those are only reported correctly if
  I log into Xorg. And indeed performance in Xorg sessions is much
  higher, more like what I would expect.

  P.S. Performance on this machine is much worse in upstream GNOME
  without triple buffering. So triple buffering is doing its job.
