AC:Valhalla GPUsage issues (latest DXvk/VKd3d builds).

[gkoulou96]

I can launch the game on DX12 fine, when i switch to Vulkan in a futile effort to fix perf, i get "Unable to initialize graphics system. GPU does not support DX12.", on GTX 1080 @ 565.90. Any possible solutions?

You have to use dxvk's dxgi.dll (and maybe d3d11.dll) too.
fwiw vkd3d-proton does not work very well with the Pascal generation so you are not likely to get more performance.

Edit: though i see you mention dxvk in title so you probably know that.

Managed to get it to work, but it freezes after loading screen with the character.

Try latest master i guess https://github.com/HansKristian-Work/vkd3d-proton/actions/runs/11389632572

I suspect GPU usage skyrockets and might just runs out of memory or sth, is there any workaround?

[Blisto91]

You could try making a file called dxvk.conf next to the exe and insert dxgi.maxDeviceMemory = 4000 which would tell the game you only have 4GB of vram. Though the game might just ignore it or not be able to lower it anyway.

The issue is persistent, i already limited my vram usage but it freezes no matter what
