This comment is tough because in its wrongness, it reveals a greater problem with Linux gaming. I think you’re right that it’s probably not ready outside of SteamOS. But it’s not correct to say it’s not ready in general. They are several distros that have all the latest features for modern gaming, the issue is you weren’t recommended even one of them. Pop_OS is currently outdated since they are working on their new desktop and mint is on the Ubuntu LTS version meaning they are both significantly behind. The community needs to take that into account when recommending things. That’s the reason I only recommend Bazzite. Cause it’s the closest to a SteamOS experience.
