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
6.11.3-zen1-1-zen
Hyprland

Yep, I tried that as well. I have the exact same file in
/gamedrive//SteamLibrary/steamapps/common/Diablo IV/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.
What are the available options? I haven't tried this.
Thanks a bunch!
Looking at ProtonDB, I don't think it's worth the trouble. All users seem to be reporting the same issues as you, so it's probably just the nature of running it in Proton.
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:
gamemoderun %command%in steam launch optionsI 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.
