Now i just past the .sl2 file in $HOME/Games/Heroic/Prefixes/EldenRing/pfx/drive_c/users/steamuser/AppData/Roaming/EldenRing/ ?

I did a tree on the folder and found a few references to elden ring but i had no idea what to do with it. The tree output can be found at https://pastebin.com/wYMG8D7L

So i assume 3992344196 is my game id. But when entering : .local/share/Steam/steamapps/compatdata/3992344196/pfx/drive_c/users/steamuser/AppData/Roaming i dont see a elding ring folder. Only a microsoft folder with nothing usefull in it. Using the find command im also unable to find a .sl file:

find . -type f -name “*.sl”

Returns nothing

Thanks for your respons! But i have a problem The game id you mentioned is indeed the one for eldenring but i dont have that id in my .local/share/Steam/steamapps this i think bc steam doesnt recognize the game it just shows eldenring.exe without a logo or something. How can i find the game id of it?

Yes i can, when changing it from wine staging to proton it doesn’t launch while it does launch on steam using proton. I have set the wine prefix to ~/.steam/root/steamapps/compatdata/783770/pfx where 78… is the game id i think.
