Abstract
An application/game server comprising a central processing unit to process application/video game program code and a graphics processing unit (GPU) to process graphics commands and generate a series of video frames for the application/video game; one or more back buffers to store video frames as the video frames are being created in response to the execution of the graphics commands; a front buffer-outputting the video frame for display one scan line at a time at a designated scan out frequency, a subset of scan lines stored in the front buffer being associated with a vertical blanking interval (VBI); and a frame processing module to begin copying a newly completed frame from the back buffer to the front buffer before the video data for a prior video frame stored in the front buffer has not been fully scanned out.
