Alright we can ignore the benchmark results [1]. And let's not focus on 550-560 performance differences anymore. We know the main performance problem in 560 by a long way and it will either require a new driver (that is probably not "560") [2], or a redesign of triple buffering [3].
So this is now triaged and I have a plan for GNOME 48.

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.
