Quoting: OfcaThen I don't know what's different. I'm using drivers 455.45.01, although I doubt newer drivers would cause the breakage. My Lutris settings are pretty much default: Proton-5.21-GE-1 as runner, Esync on, Fsync off (my stock 5.9.0 kernel doesn't support that)

For me, it runs on stable drivers without crashes. I was trying yesterday with the beta one and it was running the benchmark but was crashing when loading or starting a new game.

I have an RTX 2060 by the way. On Manjaro and with latest 5.9 kernel.

And also, it works with the proton 5.21 from gloriousEggroll as well. To be honest, the only thing that I think is necessary is to build the vkd3d dlls from the latest master and put on the game folder or on system32 and syswow64 of your wineprefix.

Yes. This won't be needed once GE decides to release new version, since he updates VKD3D all the time ;)

will try tonight

Hmm... Turns out my doubts were misplaced. It would seem that problem lays within beta drivers and you may want to try the stable ones. At least according to one of redditors.

Yep works with 455.45.01. Ironic, as I'd chosen the beta driver for better Vulkan support.

Hi guys,
I've been following forum posts, and trying to get the game to work, but I keep getting the following error message:
This message shows up at the first splash screen..

=====================================
Non-DX12 Video Card
Unable to initialize graphics system. GPU does not support DX12.
=====================================

I'm currently running a Radeon 5700xt so I'm pretty sure the hardware is not the issue. I was able to clone and compile the d3d12.dll for both 32 and 64bit drivers from https://github.com/HansKristian-Work/vkd3d-proton repo. I tried both the master and the ac-valhalla branch but I get the same message for both.

I have the Proton-5.21-GE-1 runner installed, with the DXVK/VKD3D disabled in Lutris. I've copied the d3d12.dll (64bit) to the Assassins Creed Valhalla and SysWoW64 directories. I've also copied the d3d12.dll (32bit) to the System32 directory. I feel like I'm missing something simple to get passed this issue.

Any help would be greatly appreciated!! Thanks..

Based on posts i've seen I believe that there is currently a but in the support for ATI cards and vkd3d which means it isn't working, at the moment it's NVidia only. though I'm sure there is a fix in the works

Yes; it's indeed something simple: you are missing a bit of patience, or nvidia GPU. ;)

Got it running by compiling wine-tkg and vkd3d-proton as well. Avg. of 38 fps on ultra settings at 5120x1440. A lot of stuttering, perhaps due to my CPU.

Still not great performance. Avg. of 52 fps, ultra 5120x1440, RTX 3080, 5950X. A lot of stuttering in the benchmark.

Yesterday has worked for me too finally. Loaded the game and successfully run the in-game benchmark.

The secret was to create an empty prefix, different than the Ubisoft Connect one.

Here below my additional setup:

• Proton-TKG 6.0rc1.rc3.gfce121fc


• dxvk commit 0b4e16. file d3d11.dll copied in the executable directory;


• vkd3d-proton commit cf4fbe47. file d3d12.dll copied in the executable directory;


• A clean Wine prefix;


• Esync disabled;


• Fsync disabled.

here the result:



Edit 12th Jan: apologies, I noticed just now there was a typo on the 3rd bullet point above.
