Ive used it for 1.5 years with absolutely no issue. I made a separate steam account just in case, but honestly even if i couldn’t use steam I’d still never put windows on there. Id much rather keep linux on it and just run games with lutris like people who have linux gaming pcs do. Steam makes it super easy and convenient but it isnt necessary for linux gaming.
Linux doesnt install things like windows does. A tar file is just an archive. What you did is basically the equivalent of copying a program’s Program Files. Itll still work if you just run the exe from the folder, but there’s no registry entry, no start menu shortcut, no desktop shortcut until its created by you or the installer on Windows.
