## Name

VkPresentTimesInfoGOOGLE - The earliest time each image should be presented

Loading… please wait.

## C Specification

When the `VK_GOOGLE_display_timing` extension is enabled, additional fields can be specified that allow an application to specify the earliest time that an image should be displayed. This allows an application to avoid stutter that is caused by an image being displayed earlier than planned. Such stuttering can occur with both fixed and variable-refresh-rate displays, because stuttering occurs when the geometry is not correctly positioned for when the image is displayed. An application can instruct the presentation engine that an image should not be displayed earlier than a specified time by adding a `VkPresentTimesInfoGOOGLE` structure to the `pNext` chain of the `VkPresentInfoKHR` structure.

The `VkPresentTimesInfoGOOGLE` structure is defined as:

    // Provided by VK_GOOGLE_display_timing
    typedef struct VkPresentTimesInfoGOOGLE {
        VkStructureType               sType;
        const void*                   pNext;
        uint32_t                      swapchainCount;
        const VkPresentTimeGOOGLE*    pTimes;
    } VkPresentTimesInfoGOOGLE;

## Members

- `sType` is a VkStructureType value identifying this structure.

- `pNext` is `NULL` or a pointer to a structure extending this structure.

- `swapchainCount` is the number of swapchains being presented to by this command.

- `pTimes` is `NULL` or a pointer to an array of `VkPresentTimeGOOGLE` elements with `swapchainCount` entries. If not `NULL`, each element of `pTimes` contains the earliest time to present the image corresponding to the entry in the `VkPresentInfoKHR`::`pImageIndices` array.

## Description

Valid Usage

- VUID-VkPresentTimesInfoGOOGLE-swapchainCount-01247
  `swapchainCount` must be the same value as `VkPresentInfoKHR`::`swapchainCount`, where `VkPresentInfoKHR` is included in the `pNext` chain of this `VkPresentTimesInfoGOOGLE` structure

Valid Usage (Implicit)

- VUID-VkPresentTimesInfoGOOGLE-sType-sType
  `sType` must be `VK_STRUCTURE_TYPE_PRESENT_TIMES_INFO_GOOGLE`

- VUID-VkPresentTimesInfoGOOGLE-pTimes-parameter
  If `pTimes` is not `NULL`, `pTimes` must be a valid pointer to an array of `swapchainCount` VkPresentTimeGOOGLE structures

- VUID-VkPresentTimesInfoGOOGLE-swapchainCount-arraylength
  `swapchainCount` must be greater than `0`
