Abstract: Embodiments of the present invention provide end-to-end frame time synchronization designed to improve smoothness for displaying images of 3D applications, such as PC gaming applications. Traditionally, an application that renders 3D graphics functions based on the assumption that the average render time will be used as the animation time for a given frame. When this condition is not met, and the render time for a frame does not match the average render time of prior frames, the frames are not captured or displayed at a consistent rate. This invention enables feedback to be provided to the rendering application for adjusting the animation times used to produce new frames, and a post-render queue is used to store completed frames for mitigating stutter and hitches. Flip control is used to sync the display of a rendered frame with the animation time used to generate the frame, thereby producing a smooth, consistent image.

Abstract: A method includes capturing an interaction of a user of a data processing device therewith at a level of a user space through a process executing on the data processing device, and communicating the captured user interaction as an event from the user space to a kernel space associated with an operating system executing on the data processing device. The method also includes incorporating, through the kernel space, the communicated event as a feedback to an algorithm executing on a processor of the data processing device communicatively coupled to a memory. The algorithm is configured to modify a current performance state of the processor based on threshold levels of utilization of the processor. Further, the method includes automatically switching, based on the algorithm execution, the current performance state of the processor to a higher power state or a lower power state thereof additionally in accordance with the communicated event.
