Description

VK_EXT_swapchain_maintenance1 adds a collection of window system integration features that were intentionally left out or overlooked in the original VK_KHR_swapchain extension.

The new features are as follows:

  • Specify a fence that will be signaled when the resources associated with a present operation can be safely destroyed.

  • Allow changing the present mode a swapchain is using at per-present granularity.

  • Allow applications to define the behavior when presenting a swapchain image to a surface with different dimensions than the image. Using this feature may allow implementations to avoid returning VK_ERROR_OUT_OF_DATE_KHR in this situation.

  • Allow applications to defer swapchain memory allocation for improved startup time and memory footprint.

  • Allow applications to release previously acquired images without presenting them.

Promotion to VK_KHR_swapchain_maintenance1

All functionality in this extension is included in VK_KHR_swapchain_maintenance1, with the suffix changed to KHR. The original type, enum and command names are still available as aliases of the KHR functionality.
