DXGI_FRAME_STATISTICS_MEDIA structure (dxgi1_3.h)
Used to verify system approval for the app's custom present duration (custom refresh rate). Approval should be continuously verified on a frame-by-frame basis.
Syntax
typedef struct DXGI_FRAME_STATISTICS_MEDIA {
UINT PresentCount;
UINT PresentRefreshCount;
UINT SyncRefreshCount;
LARGE_INTEGER SyncQPCTime;
LARGE_INTEGER SyncGPUTime;
DXGI_FRAME_PRESENTATION_MODE CompositionMode;
UINT ApprovedPresentDuration;
} DXGI_FRAME_STATISTICS_MEDIA;
Members
PresentCount
Type: UINT
A value that represents the running total count of times that an image was presented to the monitor since the computer booted.
PresentRefreshCount
Type: UINT
A value that represents the running total count of v-blanks at which the last image was presented to the monitor and that have happened since the computer booted (for windowed mode, since the swap chain was created).
SyncRefreshCount
Type: UINT
A value that represents the running total count of v-blanks when the scheduler last sampled the machine time by calling QueryPerformanceCounter and that have happened since the computer booted (for windowed mode, since the swap chain was created).
SyncQPCTime
Type: LARGE_INTEGER
A value that represents the high-resolution performance counter timer. This value is the same as the value returned by the QueryPerformanceCounter function.
SyncGPUTime
Type: LARGE_INTEGER
Reserved. Always returns 0.
CompositionMode
Type: DXGI_FRAME_PRESENTATION_MODE
A value indicating the composition presentation mode. This value is used to determine whether the app should continue to use the decode swap chain. See DXGI_FRAME_PRESENTATION_MODE.
ApprovedPresentDuration
Type: UINT
If the system approves an app's custom present duration request, this field is set to the approved custom present duration.
If the app's custom present duration request is not approved, this field is set to zero.
Remarks
This structure is used with the GetFrameStatisticsMedia method.
