Vulkan Devices Quirks

VK_INCOMPLETE result when calling vkEnumeratePhysicalDevices

Sometimes the vulkan loader will report a VK_INCOMPLETE code when enumerating a system's physical devices list. This is not a real error, but it's the loader's way to warn that the returned list might be smaller than the previously queried pPhysicalDeviceCount value due to a driver issue.

It is ok to continue sorting/selecting your devices after that, just expect a return value of vkEnumeratePhysicalDevices not being VK_SUCCESS without being an error
