DotA 2 Vulkan problem

DotA 2 with Vulkan no longer works today, I played yesterday and now it refuses to launch, it is working with default opengl.

I use nvidia-dkms and linux-zen

Re: DotA 2 Vulkan problem

Shouldn't you try to open Dota with vulkan in terminal and post some logs??

Re: DotA 2 Vulkan problem

I've got the same problem, but not only with Dota. I tried launching a game through proton and it won't launch. I think it has something to do with Vulkan perse, but I am not sure.

Edit: I tried launching steam through terminal and start Dota, however, no error message shows up so there is nothing really worth sharing. I've got this message once though
AllocInternal(): CUtlinkedlist overflow

Re: DotA 2 Vulkan problem

Well i am not expert however i would assume that it should be something at vulkan/steam side, however i might be wrong :-)

Yes I think it is something related to Vulkan, because I can play steam games running OpenGL. However, the moment I try to launch a game using Vulkan (Dota2 or Proton games) they just won't launch.

Couldn't find much online so far, but I am still looking.

Re: DotA 2 Vulkan problem

For anyone having this problem still, there is a solution. At least this worked for me.
https://github.com/ValveSoftware/Dota-2/issues/1619

A user by the name of nascheme said:

Cleaning the shader cache seemed to fix it for me.

cd <STEAMAPPS>
find shadercache -type f -print0 | xargs -0 rm
Be careful to run that in the correct folder.
