AMD has Mesa drivers for graphics, which are better-optimized than Nvidia's proprietary Linux Vulkan drivers. It can be fixed in software, but Nvidia's only barely started to catch up.
The focus for Nvidia's GPU stack on Linux is getting CUDA working, which means that some traditional raster features get neglected.
NVIDIA also cares about Hollywood and CAD/CAM shops.
I learnt three times that AMD isn't necessarily better in Linux as advertised, now I don't care any longer.
