Structure holding the replacement function pointers for frame interpolation to work Not all extensions are supported for now Regarding specific functions:

  • queuePresentKHR: when using this one, the presenting image should be in VK_IMAGE_LAYOUT_SHADER_READ_ONLY_OPTIMAL state

  • getLastPresentCount: this function isn’t part of Vulkan but the engine can use it to get the real number of presented frames since the swapchain creation
