I’ve been using Linux for over 20 years and I don’t get it either. I don’t know why a vocal minority get so fixated on it. It’s not like it’s the only manufacturer with proprietary drivers. As long as the drivers work and are easy to install I don’t see a problem.
I’ve used ATI/AMD cards equally over the years and I’ve always ended up having more problems overall with them than with Nvidia cards & drivers. If I were inclined to generalize I could say that open source drivers are apparently lower quality, right? 🙂
But that would be just as silly as the other way around. I don’t think that open or closed drivers, in itself, automatically says anything about quality.
If closed source drivers really were a problem then Nvidia wouldn’t be used by 80% of Linux gamers.
