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)
Blender supports cuda for much of its gpu work. It will work with amd. And there are projects allowing gpu rendering via amd. But they are (and have been for a while) a long way behind the cuda stuff.
For major rendering projects nvidia is still the fastest set up to use.
