Recommendation: run the game in vulkan

[WreckWren]

DXVK is a drag & drop installation, works on Windows, and you can pick up 10-50fps on average. This will disable & impact some third party features, but many of you of course are unable to use these already. This does not result in a big improvement in most games, but the ACO twins are extraordinarily poorly optimised and do net a big improvement.

Hilarious that the optimisation is so BAD that these games were written in DX12, translated to DX11 in Windows, and are MORE efficient being translated AGAIN to Vulkan! Ubi's dev team really were absolutely hopeless with both these titles.

If anyone wants a guide to install for any reason, drop a reply.

Can I have a guide please.

Sure:

Download the latest release from the github:
https://github.com/doitsujin/dxvk/releases

Drag & drop the relevant .dll files (d3d11 & dxgi) to the same directory as where ACO is installed (specifically where the .exe is located)

Install the Vulkan SDK:
https://vulkan.lunarg.com/

And launch the game!
There will be stuttering at first as the game compiles all the shaders again. Give it half an hour to an hour of play time to perform at best.

If anyone works out a way to force HDR on without Ubisoft deciding for you with the "hArDwArE uNsUpPoRtEd" crap, please let me know 😊

Did you install the Vulkan runtime? This requires a reboot. This step is not optional, otherwise your game will obviously not launch since you will be trying to run the game in a runtime that is not properly installed. Needless to say, also, that if you want to run in Vulkan your system must be capable of this.

I will put together an ELI5 guide this evening.

With your recommendation i have a performance decrease.

Pics of framerate graph or it didn't happen. I suspect you are referring to shader compilation time mentioned in the OP.

Thanks for sharing this, I was having a terrible time with DirectX, crash after crash, with this workaround the game is stable AF.
Specs:
-RTX3060
-Intel i1180H
-16GB RAM

my game crashes on startup

Glad to hear you had a positive experience.

Try a different version/release of DXVK. They do new releases relatively frequently & I would bet that one will work for you.
