I've been using Linux with NVidia since ... wow, what time the 9600 was around again? I've been with many new generations and I am currently using a 3090 and I can't remember ever having a problem. The performance is almost the same (depends on the use-case, sometimes better, sometimes worse) as on Windows, at least when using things like Tensorflow and the like. The only problems I ever had were when I tried to get a few ATI/AMD cards to run on someone else's computer. But hey, at least people praise them for being cool with the FOSS community I guess?
