  • I have tried the PROTON_HIDE_NVIDIA_GPU=1 before and I can tell you it definitely helps. The game is unplayable without it, to be honest. The VRAM still fills up but it’s not instantly, it takes quite a while. Makes the problem manageable.

    Edit: Several people have reported that this VRAM bug doesn’t happen on AMD cards. If you happen to have one, you might give it a try.

    Unfortunately I do not. I bought this nvidia card long before I switched to Linux and boy, do I regret it.


  • I believe that config needs to be in the working directory context of the game, but maybe I’m misremembering that.

    Yep, I tried that as well. I have the exact same file in /gamedrive//SteamLibrary/steamapps/common/Diablo IV/

    If upon starting your game, it immediately starts using 10GB of vid mem, then that is what is needed by the game to run. Setting this to 8GB is going to magically make it run by using less.

    But the game does quickly fill 10GB with both low and ultra settings. It hints to me that the game doesn’t need 10GB to run. It just makes use of the available memory. My theory is that using 8GB would at least make my desktop usable. Currently, switching to my browser in the second monitor can break the game. If I never focus out of the game it doesn’t break.

    • Problem occurs in both x11 and wayland
    • Window vs fullscreen makes no difference
    • ProtonDB has some additional flags, I tried them all
    • I tried several proton versions from 8 to 9, GE and no GE. Made no difference

    See if you can force a specific renderer that is more stable.

    What are the available options? I haven’t tried this.

    Thanks a bunch!
