Linux Gaming

Linux Mint, Ubuntu, and (to a lesser extent) Fedora are basically THE best "desktop" distros. They support a range of desktop evnironments but are mostly built around "just working". If you are coming from windows, you can't really do wrong with KDE Plasma or (Linux Mint) Cinnamon as both of those are "more Windows than Windows" as they heavily crib from the vista/7 era. But even whatever the current default Ubuntu desktop environment is called at this point is fine.

So it mostly boils down to what GPU you have.

• AMD? Any of the above
• nVidia? Mint and Ubuntu make this trivial as they have a nice GUI method to turn on the proprietary (so "good") nvidia drivers. Fedora involves a few terminal commands and seems a lot more prone to getting borked and needing to reinstall the drivers. But I run Fedora with nvidia and have zero concerns.
• Intel? May Erastil protect you.

Personally? I use Fedora with KDE Plasma for my desktop OS. While I am not huge on either, I vastly prefer flatpaks to snaps for app delivery. And I have a lot of concerns with how Canonical/Ubuntu is handling update cadences as a way to promote their enterprise OS.

But also? The beauty of Linux is that it is trivial to reformat. And the best thing you can do is just distro hop a bit for the first month or so. Install Mint. If you find something bothering you, look at what distro does that better and install that. New distro a piece of shit? Embrace Fedora. And so forth.

The reason so many of us get rather tribal about our distro or desktop environment is because we chose them. In the Windows space, you get cranky and hope Microsoft undo something you hate in the next five years (or you install sketchy third party plugins that never work). In the Linux space? You find out that a bunch of people also hate that clippy went away and built an entire distro around support for clippy like behavior. Or whatever.

If you put a bit of effort in you can even re-use your home directory and lose zero data. Although, personally, I have never had the patience for that. Games go on dedicated drives that migrate between installs. And personal documents get backed up to my NAS. So a reformat is just wiping the OS drive, installing the new distro, and then spending a minute or two to figure out what weird ass name an app I like is in the package manager.
