I've read the article from itsfoss about how to share a game between Linux & Windows and it got my excited, I've been undecisive about using Linux because I couldn't play video games but now I can!
From what I understood, SteamPlay on Linux will -according to what I understood- download the Windows binaries of a game along with the Proton magic (mostly the binaries/programs required by that game) then run it.
I made a new partition, made a SteamLibrary folder which has a Rocket League (Windows steam downloaded), since they discontinued their Linux support recently I thought they would be a great first attempt.
Anyway, the game runs perfectly on Windows, I switch to Linux and it started downloading somethings (few 100 MBs) and I I thought that's it, upon finishing those things, it started downloading the game itself.
I was wondering if there's a chance to share my entire games library between Windows/Linux without having to download & keep two copies of each game.
P.S: I found an article about using Wine to install the Windows Steam & using that for the shared library directly, If that's the only option out there I will definitely use it but I thought, and I could be wrong, that using Linux Steam + SteamPlay(Proton) would get me better performance than using Wine only.
