http://bugs.winehq.org/show_bug.cgi?id=49028 --- Comment #8 from Stian Low <wineryyyyy(a)gmail.com> --- It's not very clear but it might be the case that X-Plane Demo only offers OpenGL. The splash screen reads: This is X-Plane 11.55 (64-bit, OpenGL) Web Demo Download If Vulkan is not supported by the demo then it explains why my logs are missing Vulkan device detection that appear for original reporter. I don't understand a why X-Plane team would make such a decision to disallow Vulkan testing for a demo. Regardless, the full version will be tested just in case someone made such an odd decision. X-Plane 12 also offers a demo and only mentions Vulkan so I'll test it also in attempt to reproduce VK_KHR_external_memory_win32 logs. It's 25 GB which also seems like an odd decision just to simply demo. -- Do not reply to this email, post in Bugzilla using the above URL to reply.
