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

    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 edited my comment again around the same time you were replying. You might want to take a look to see if anything I added helps.
