Abstract
This invention discloses a method for executing vertex shader in a computer system, the method comprising running software vertex shader for a predetermined vertex shader command in a CPU thread when a GPU is overloaded by vertex shader execution, buffering the output of the software vertex shader, running hardware vertex shader for z-values of the vertex shader command, and replacing z-values from the software vertex shader with the z-values from the hardware vertex shader, wherein the vertex shader overloading can be lessoned yet the vertex shader z-values are consistently transformed by the hardware vertex shader.
