Missing Vulkan extension.

[Hubert787]

I'm trying to run x plane 11 with wine using Vulkan rather than opengl. X plane 11 runs native on Linux but lots of 3rd party add-ons are Windows or Mac only.

In opengl, it works fine but Vulkan would be much preferred due to higher fps. However, when trying to run in Vulkan mode on both wine 5.5 and proton 5.0 I get this error: "The graphics card or driver lacks support for a required extension: VK_KHR_external_memory_win32". This is with Arch on a gtx 1070 but it appears to be the case on all systems. Is there anyway to fix something like this, maybe by compiling wine without blacklisting some of the extensions? Any other way?

Thanks, Hubert.

Try installing libvukan1 libs
In terminal: sudo apt install libvulkan1 libvulkan1:i386

Reboot to apply settings.

Hope that helps.

Hmmm....
VK_KHR_external_memory_win32 is a Windows only Vulkan extension.
So probably a non-starter...
As Wine only passes through Vulkan instructions to the native Linux Vulkan API.

So I guess that means no hope then. Is this something that could potentially get solved in a future version of wine?

Well don't take my word for this!
You can try filing a Wine bug for this issue.
Otherwise it is very unlikely this issue will get looked at...
