Hello, apparently hanging out in Lemmy inadvertently makes you thinking about using Linux. I am planning to install Linux Mint cinnamon on an older laptop, which I want to bring to LAN Parties. From what I read I can just format my C:\ windows disk, install Linux via bootable drive and from what I understand, proton is basically included when installing steam after setting up my new Linux OS? Thanks for your comments:)
Since you have LAN parties in mind, be sure to check this list to know what games are (or are not) well supported by Proton under Linux.

Proton is the compatibility layer that allows Seam games developed for Windows to run under Linux. Some games, unfortunately, may have problems that cause you to be left out.
