Quoting: KilgourianHi 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..

Quoting: GuestHas anybody tried launching AC:V with an AMD GPU? The latest mesa from git should be able to fully support DX12 -> link
I still got no luck starting up that game. Tried with runners like lutris 6.0rc1, wine-stg 6.0rc6, dxvk 1.7.3 and dxvk 1.7.3 with latest vkd3d-proton-libs (d3d12.dll). It still says "Unable to start the game." followed by some activation error.

@LordDaveTheKid: Why did you copy d3d11.dll in the game's directory, when the game is said to be DX12-only?

Quoting: GuestDid you start up both prefixes then? UbisoftConnect and AC:V separately?

Edit: That's not working for me. If I start ACV in one bottle (prefix), it demands UbisoftConnect (even if it's started in another bottle).

Quoting: GuestOk, thanks!
So you got two prefixes here: uplay and ac-valhalla-pfx

Quoting: GuestThe prefix "ac-valhalla-pfx" is completely blank? If I add an empty wine-prefix there, it says "Unable to start the game. The uplay installation was not found...."

Quoting: GuestHm, no idea what's the difference here. The way you described it doesn't work here. I cannot start up ACV without lauching UbisoftConnect first. And if I launch UbisoftConnect and afterwards ACV within, I get the error "Unable to start the game. The game cannot be activated now. Try again later."
Must be something with Ubisoft. Maybe I tried to launch it too often =/

Quoting: GuestUbuntu (Budgie flavor), 5.10 kernel, lutris 0.5.8.2 pretty much standard linux config. Maybe Ubisoft don't like vpns. I'll try another day.
