I’ve been having a couple of troubles playing Diablo IV, though they seem to be a lot worse with the new expansion. After a while of playing for a while, the game seems to leak VRAM and makes my desktop pretty unstable. Alt+tabbing occasionally breaks the game, the image freezes but I still hear the noises of the menus opening and such. If I don’t alt-tab the game doesn’t break.

I have found this reddit thread about setting a dxvk file to limit the amount of VRAM available to Diablo. I set up the max VRAM to 8gib but mangohud still reports 10gb being used. I tried setting the DXVK_CONFIG_FILE flag but that also doesn’t seem to work. Mangohud report 10gb VRAM very fast. DXVK file contents:

dxgi.maxDeviceMemory=8192
dxgi.maxSharedMemory=8192

Decreasing the graphic settings just slows down the problem, it doesn’t prevent it.

Launch options: DXVK_CONFIG_FILE=/gamedrive/dxvk.conf mangohud %command%

Specs:

Intel i7-12700K @ 4.900GHz
NVIDIA GeForce RTX 3080 (driver version: 560.35.03)
64GB DDR4
EndeavourOS Linux

    With i install and play i get the same issue as you, vram filling up, framerate going down, ground texture going grey and if i alt-tab at that point the game crashes.

    What i have done and works - at least in my case - is the following:

    • dxvk.conf with memory limit in …/steamapps/common/Diablo IV/
    • gamemoderun %command% in steam launch options
    • textures set to medium in game.
    • proton GE 9-15
    • I also have the high resolution assets disabled in the dlc options in steam.

    I can play fine with these, vram never goes above the limit i have set in dxvk.conf. I am doing this on endeavour, default kernel (not zen), 12500H and a 8GB 4060.

    The limit i set is at 6GB for the vram. The only difference might be that this is a laptop with igpu so anything else OS related is rendered on the igpu and i don’t use a second monitor. It plays fine and i can alt-tab without issues.
