VkPresentTimeGOOGLE

The earliest time image should be presented

The VkPresentTimeGOOGLE structure is defined as:

typedef struct VkPresentTimeGOOGLE {
    uint32_t presentID;
    uint64_t desiredPresentTime;
} VkPresentTimeGOOGLE;
  • presentID is an application-provided identification value, that can be used with the results of vkGetPastPresentationTimingGOOGLE, in order to uniquely identify this present. In order to be useful to the application, it should be unique within some period of time that is meaningful to the application.
  • desiredPresentTime specifies that the image given should not be displayed to the user any earlier than this time. desiredPresentTime is a time in nanoseconds, relative to a monotonically-increasing clock (e.g. CLOCK_MONOTONIC (see clock_gettime(2)) on Android and Linux). A value of zero specifies that the presentation engine may display the image at any time. This is useful when the application desires to provide presentID, but does not need a specific desiredPresentTime.
