  +Demonstrates the use of VK_EXT_conditional_rendering to conditionally dispatch render commands based on values from a dedicated buffer. This allows e.g. visibility toggles without having to rebuild command buffers ([blog post](https://www.saschawillems.de/?p=3098)).

  +#### [05 - Debug markers (VK_EXT_debug_marker)](examples/debugmarker/)
  Uses the VK_EXT_debug_marker extension to set debug markers, regions and to name Vulkan objects for advanced debugging in graphics debuggers like [RenderDoc](https://www.renderdoc.org). Details can be found in [this tutorial](https://www.saschawillems.de/?page_id=2017).
