Dota 2 doesn't start with Vulkan

[bn1knb]

Hi there,

i got my Lenovo g505s and steam.
I went through the vulkan installation guide on wiki and set Dota to start up with it, but it just doesn't start at all.
Log file from starting steam to launch Dota 2 :

It's ok with gl setting.
Driver in use : radeon.
My make.conf file :

Dear guru, what kind of information do you need to solve this?

P.S.
I have some problems with swithcable graphics in my laptop...

Hello bn1knb,

Since you mentioned dota 2, did you download the dlc and set the "-vulkan" option in the boot settings in steam? Did you also get the vulkan-loader package?

Edit: Also check in the dota settings in game to see if it is shaded. For me, I had not downloaded the dlc so I took about a day to figure out why I had no vulkan support haha. Also have mesa built with the vulkan use flag if you have not I suppose.

Hello youand28,

thank you for your reply.

bn1knb,

Try to see if it is for dota only. Test vulkan on other applications other than dota or steam in general. You can compile vulkan-loader with demos use flag and run vulkaninfo. You can also run the dolphin emulator if you want something free to test vulkan as well. Is mesa also compiled with vulkan flag? Sorry if you did already; I'm just verifying since you did not state it in the response.

I experienced same issue. Vulkan were working fine before some update, not sure - world or dota. Furthermore - after this update, dota starts with invisible window, until you remove vulkan.
