No worries, bazzite has you covered there too.

I can second bazzite. It. Just. Works. But it is built differently from the distros that everyone has heard of like arch & Ubuntu, so it’s best to read up on how to install non-flatpak programs.

Keep in mind that steam can run Windows programs for you with it’s emulation layer. It’s not the only option, but it is convenient as an app launcher.
