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.
