Embodiments of the present invention are directed to a method and computer program product for performing physics simulations and graphics processing on at least one graphics processor unit (GPU). Such a method for performing physics simulations and graphics processing on at least one GPU includes the following steps. First, physics simulations are executed on a first device embodied in the at least one GPU. Then, graphics are processed on a second device embodied in the at least one GPU responsive to the physics simulations executed on the first device. In an embodiment, the first device and second device are embodied on a single GPU. In another embodiment, the first device is embodied on a first GPU and the second device is embodied on a second GPU.
