Patent ID: 7782327

Claim:
A method for accelerating the processing of graphics images by a computer for display on a single visual output device screen through use of a plurality of video cards, comprising the steps of: intercepting graphics commands issued by an application; generating multiple, modified graphics command streams; assigning each of said multiple, modified graphics command streams to different video cards selected from said plurality of video cards; processing at each of said video cards the assigned modified graphics command stream and generating an output signal; synchronizing the output signals by said plurality of video cards; combining the output signal from said plurality of video cards into a single graphics output signal, wherein said combining comprises sequentially routing selected portions of said output signals from said plurality of video cards, wherein routing is determined by a vertical refresh rate of said output signals from said plurality of video cards, a vertical resolution of said output signals from said plurality of video cards and a load balancing ratio assigned to each of said plurality of video cards; and displaying said single graphics output signal on a single visual output device whereby said visual output device displays images defined by said intercepted graphics commands with accelerated performance.
