I’d have to go parse through the script, though I’m certain someone else here already knows, but amongst other packages, proton, wine, steam and video drivers seem to be what it installs. I had to do all that manually on Mint and since it was my first Linux system I set up as a gamer I am sure I have some package versions set differently/incorrectly. Cachy takes the guesswork out of it.

I am olde and have been building gaming systems for many years. CachyOS is the easiest OS that I’ve ever set up. Am in a game playing within minutes. Even Windows was never so easy.
