Abstract
A computer system includes a processor, a memory, first and second graphical processors that have different operating characteristics, a switching mechanism coupled to the graphical processors, and a display coupled to the switching mechanism. The switching mechanism is configured to couple a given graphical processor to the display, and is initially configured to couple the first graphical processor to the display. Furthermore, a program module, which is stored in the memory and configured to be executed by the processor, is configured to change a configuration of the switching mechanism thereby decoupling the first graphical processor from the display and coupling the second graphical processor to the display. Note that the changing of the configuration and switching module operations are configured to occur while an operating system is running and are based on the operating condition of the computer system.
