I'll try to get my GPU to at least get detected as a Vulkan device to reproduce the VK_KHR_external_memory_win32 logs.
I get practically the same Log.txt and greyed out Vulkan Graphics Setting option for GE-Proton 10-11 and 10-15. This is surprising because Proton and forks typically work around upstream WINE Vulkan issues.
I'll try another machine with a different graphics card to see if I can get it to detect a Vulkan device to reproduce VK_KHR_external_memory_win32.
VK_KHR_external_memory_win32 does not have many examples in the wild to alternatively reproduce the logs.
Maybe the VK_KHR_external_memory_win32 log is derived this lib which lists X-Plane as a user: https://github.com/GPUOpen-LibrariesAndSDKs/VulkanMemoryAllocator
Many other apps are listed which may be useful for reproducing VK_KHR_external_memory_win32 related discrepancies.
