A system for hosting video games comprising: a game server comprising a central processing unit to process video game program code and a graphics processing unit (GPU) to process graphics commands; one or more back buffers to store video frames in response to the execution of the graphics commands; a front buffer to receive a video frame for rendering on a display and 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); a frame processing module to increase the number of scan lines associated with the VBI to increase the likelihood that a new frame will be completed in a back buffer and ready for transfer to the front buffer at a time during the VBI.
