Embodiments of the present invention are directed to provide a method and system for applying automatic power conservation techniques in a computing system. Embodiments are described herein that automatically limits the frame rate of an application executing in a discrete graphics processing unit operating off battery or other such exhaustible power source. By automatically limiting the frame rate in certain detected circumstances, the rate of power consumption, and thus, the life of the current charge stored in a battery may be dramatically extended. Another embodiment is also provided which allows for the more effective application of automatic power conservation techniques during detected periods of inactivity by applying a low power state immediately after a last packet of a frame is rendered and displayed.

Method and system for artificially and dynamically limiting the framerate of a graphics processing unit

A system, method, and computer program product are provided for a dynamic display refresh. In use, a state of a display device is identified in which an entirety of an image frame is currently displayed by the display device. In response to the identification of the state, it is determined whether an entirety of a next image frame to be displayed has been rendered to memory. The next image frame is transmitted to the display device for display thereof, when it is determined that the entirety of the next image frame to be displayed has been rendered to the memory. Further, a refresh of the display device is delayed, when it is determined that the entirety of the next image frame to be displayed has not been rendered to the memory.
