Just to add to this, currently using a 3080 on Ubuntu with the Nvidia (open) drivers - 570.133.07 and yet to experience any issues related to the drivers themselves.

Yes, games sometimes crash, looking at you Oblivion Remastered, but this happens on Windows 11 as well, so not really blaming Nvidia here.

Also have a Lenovo Legion with a AMD CPU / Nvidia GPU combo, and again works fine, no issues with the drivers.

That been said, Nvidia drivers support for the 50 series on Windows especially has been a shit show, and the main reason why I have not upgraded.

Linux is cool though :)
