I think the only thing to keep in mind is that Nvidias proprietary drivers work better for Linux whereas for AMD it is the open-source ones.
I have an Nvidia card and the prop. drivers have worked flawlessly for me for years.
I know the open source drivers are closing the gap for Nvidia, and they also seem to be playing ball on that front. But for AMD the open source drivers are definitely the way to go from what I understand.
It’s impressive how this initiative has gathered 360k votes in no time yet completely stagnated ever since. I don’t think it means that the initiative is done, actually I am quite optimistic it can pass, but these things go in waves. I think every time there is a new coverage on the initiative it launches it higher, we just need some folks who have some local presence in the EU to get their audience to act. Perhaps some famous video game streamers? Has that been done already?
