I am going to buy a new graphics card and can’t choose between Nvidia and AMD. I know that Nvidia has bad reputation in Linux community but how really it works? And I heard recently their drivers got better. What can you recommend?
P. S. I don’t want any proprietary drivers (so I am talking about Nouveau or any other FOSS Nvidia driver if it exists)
Just not true anymore. Must have been years ago that you used Nvidia on Linux. As someone who has been using Nvidia GPUs under Linux (Manjaro KDE mostly), recently also under Wayland (since plasma 6), I can attest that the experience is very good, no “tons of small issues”.
Still though, since OP wants no proprietary drivers, he has to go for AMD, since nouveau is dog shit.
