Failed to initialize vulkan

[yat-L]

This pop up when I try to run dota2 on with vulkan "Failed to initialize vulkan. Please make sure your driver and GPU support vulkan" I set the launch option to -vulkan, installed the latest nvidia driver. The system setting didn't mention, but I have a geforce 840m nvidia card.

Hello @AinsworthK, Have you read through https://wiki.archlinux.org/index.php/Vulkan and confirmed vulkan works outside of steam? Are you using any other launch options?

[yat-L]

yes, I have read through the wiki page and tried remove vulkan-intel, I am only using -vulkan. What can I do to check if vulkan work outside of steam?

[kisak-valve]

There's a bunch of tests at https://github.com/SaschaWillems/Vulkan, but it may be easier to try vkquake from the AUR.

Also, you should be able to use vulkan-caps-viewer as a basic test.

I guess it is not a dota2 issue, I can't run vkquake, return "Couldn't find any Vulkan device". Geforce 840m is maxwell. according to wiki, my card is not supported, but according to nvidia , it is . https://developer.nvidia.com/vulkan-driver

Thanks for testing, I agree that this is a driver or system issue and is out of scope for this issue tracker.

If you happen to figure this out, it would be nice to know, but I will be closing this for now as it is not actionable by a Valve dev.
