Expected Behavior

Recording the app should either work, or failing to record is an expected & documented behavior.

Current Behavior

Hi, I just wanted to let you know that in future OBS will not work with Vulkan 1.0 Apps that do not activate VK_KHR_get_physical_device_properties2.
Users of our project which shipped with Vulkan 1.0 reported it, and the relating Vulkan loader issue is here:
https://github.com/KhronosGroup/Vulkan-Loader/issues/1048
It's not a bug in the loader, but will still affect OBS, as recording in fullscreen will break in future driver versions.

Steps to Reproduce
  1. Start a VK 1.0 App under Windows and it will not record the game (without VK_KHR_get_physical_device_properties2)
Anything else we should know?

Research direction

Start by reviewing the linked Vulkan-Loader issue 1048 and the OBS fullscreen recording path for Vulkan applications. Determine whether the reported Vulkan 1.0 limitation can be addressed in OBS; done means recording works with affected applications or the limitation is clearly documented.
