Wine, Lutris and Protón prefix folders, and other questions

Thank you very much friend!

One more doubt. In your guide you say this:

I want to install a game, for example Dark souls Remastered. Dark Souls may use a x64-bit launcher, or perhaps a x32-bit one

But my EOS is x64 (if I’m not mistaken). So, should I choose a prefix based on the bits of the game, or the operating system?

I’m using Lutris to create the prefix, and I can choose between x32, x64 or Auto (default).

When I used Windows 10, I could play x32 and x64 games, but I guess the Lutris prefix doesn’t work like that, which is why I have that doubt.
