From what Ive heard the issues with Nvidia on linux are less about proton not working and more about the closed source drivers being a little more effort to install, and causing issues with more bleeding edge and rolling distros because nvidia drags its feet on supporting the newer features and standards. Plenty of people use Nvidia on linux and it does come with benefits as well such as better video decoding and encoding, better work drivers, and since its not foss they can just support HDMI 2.1’s closed nonsense without having to worry about stepping on toes.

I dont use Nvidia so I cant say for sure but I feel like the solution to the typical “oh no I ran an update and everything is broken!” is to just use a stable/lts distro.
