From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

The instructions for getting it to run are all over Protondb (needs winetricks), and even then, it looks like a minority of hardware configs that have issues -- perhaps even AMD specifically.
Edit: also it looks like it may work OOTB now if you start it using Glorious Eggroll's Proton 7.2 or higher
