The present invention is directed to a method for rendering a composite image (comprising a primary object image and at least one graphical overlay) wherein the GPU and VRAM are bypassed altogether and the resulting displayed graphics are instead rendered in RAM by the CPU and copied directly to the frame buffer. This method not only avoids the data flow problems inherent to computer systems that favor system-to-video flow of data traffic (that is, computer systems that utilize an AGP) and avoids the "last-write" problem altogether, but which also takes advantage of modem CPUs having increased computational speeds (that are orders-of-magnitude greater than the speeds of legacy processors) and supports complex graphics functions that are necessarily performed by the CPU (and not the GPU) to achieve significant performance gains.
