Abstract
Techniques for calculating a predicted head pose time for a display device are described herein. A request to start a frame is generated. A target finish time stamp associated with rendering the frame is calculated. A number of VSync periods from a last VSync to a target VSync is determined based on the target finish time stamp. A target VSync time stamp is calculated based on the number of VSync periods from the last VSync to the target VSync. The target VSync time stamp is compared to the target finish time stamp. The predicted head pose time is calculated based on the target VSync time stamp and a fixed platform offset.
