Running with -vulkan only shows a RGB triangle

i'm not sure if this is expected because the Vulkan renderer is still experimental, but i couldn't find it documented anywhere: running with -vulkan only shows a full screen RGB triangle.

It does produce sound and seems to respond to input.

This is on Ubuntu Linux, AMD graphics card w/ amdgpu drivers:

Device Properties and Extensions:
=================================
GPU0:
VkPhysicalDeviceProperties:
---------------------------
        apiVersion        = 1.3.274 (4206866)
        driverVersion     = 24.0.9 (100663305)
        vendorID          = 0x1002
        deviceID          = 0x699f
        deviceType        = PHYSICAL_DEVICE_TYPE_DISCRETE_GPU
        deviceName        = AMD Radeon RX 550 / 550 Series (RADV POLARIS12)
        pipelineCacheUUID = 604006ad-74c5-5c83-34d8-a903358c60d4

OpenGL mode works fine on this system.

I'm afraid this is as far as any vulkan implementation in FSO has gotten. It's currently not possible to play FSO using vulkan.

Yes, the vulkan renderer is a stub-backend at this point. We have the infrastructure in place to build with vulkan and to initialize it, but basically all of the actual graphics backend does not yet exist.

Thanks ! Kind of suspected that. Might make sense to add a warning to the build system, or README 😄
