I can't reproduce the explanation in comment #16 for nvidia-550 being faster than nvidia-560 (at least on Turing). Though it sounds like [1], that doesn't seem to affect the shell performance itself.
We've verified that most of the shell's performance problem comes down to an architectural difference between Mesa and Nvidia drivers [2]. And while I thought triple buffering should work around that, it doesn't yet [3]. So [2] is the main fix that the Nvidia driver needs (not counting subtle power saving/scaling differences between 550 and 560). And [3] is a performance improvement to triple buffering that might be possible, and would work around the need for changes to the proprietary Nvidia driver. For completeness there is also benchmark performance [1], which is probably something most Ubuntu users won't notice in everyday usage.
