The main game I'm having problems with is an indie online title whose recent update peaked at less that 150k players. I don't care for AAA either, indie games also break on Linux.
You can definitely say "Oh just don't support Nvidia," but I bought my card nearly 10 years ago, and at the time it was the best I could afford. Upgrading to an AMD card would be great, but absolutely not happening any time soon in the current economic climate. If your response to that is "oh well get fucked ig," pretty hard to argue Linux as a universal gaming solution.
On top of all of this, it seems like everyone in this thread who's had success with gaming on Linux is saying run Bazzite, an OS I'd never heard of prior to reading responses here. That's cool if there's a distro that's actually solved a lot of gaming issues, but if I haven't heard of it, the average user is never going to find it. Maybe the title of this article should have been "Bazzite is now the best system for gaming."
