alt Hacker NewsThe AMD drivers are open source, but they definitely are not good. Have a look at the Fedora discussion forums (for example https://discussion.fedoraproject.org/t/fedora-does-not-boot-... ) to see what happens about each month.
I have no NVIDIA hardware, but I understand that the drivers are even worse than AMD's.
Intel seems to be, at the moment, the least worse compromise between performance and stability,
Although you get to set your own standards "A bug was discovered after upgrading software" isn't very illuminating vis a vis quality. That does happen from time to time in most software.
In my experience an AMD card on linux is a great experience unless you want to do something AI related, in which case there will be random kernel panics (which, in all fairness, may one day go away - then I'll be back on AMD cards because their software support on Linux was otherwise much better than Nvidia's). There might be some kernel upgrades that should be skipped, but using an older kernel is no problem.
