Linux

Linux is an operating system kernel, and a popular name for an operating system. Rubenerd has taken to calling it KDE/Linux, or sometimes Xfce/Linux. It's what you run if you can't use FreeBSD, NetBSD, or illumos for something.

Linux has become awesome for games, thanks in part to the efforts of Valve, and the Wine developers. Unfortunately, Rubenerd's current GPU is an RTX 3070, which does complicate things somewhat.
