@hydroel Two biggest drawbacks are certain games with anti-cheat not running (however some do), and peripheral support (my Thrustmaster racing wheel doesn't get force feedback).
Some games (Like Factorio) have a better native Linux version than the Native Windows version.
I use Arch Linux, but wouldn't recommend it to a novice. If you're only gaming ChimeraOS is a good place to start. If you're really new to Linux and scared to break things, an immutable OS like Vanilla may be better suited.
