Abstract: A method for graphics processing including rendering graphics for an application using a plurality of graphics processing units (GPUs). The method including dividing responsibility for rendering geometry of the graphics between the GPUs based on screen regions, each GPU having a corresponding division of the responsibility which is known to the GPUs. The method including determining a Z-value for a piece of geometry during a pre-pass phase of rendering at a first GPU for an image, wherein the piece of geometry overlaps a first screen region for which the first GPU has a division of responsibility. The method including comparing the Z-value against a Z-buffer value for the piece of geometry. The method including generating information including a result of the comparing the Z-value against the Z-buffer value for use by the GPU when rendering the piece of geometry during a full render phase of rendering.

Abstract: A method for graphics processing. The method including rendering graphics for an application using a plurality of graphics processing units (GPUs). The method including dividing responsibility for the rendering geometry of the graphics between the plurality of GPUs based on a plurality of screen regions, each GPU having a corresponding division of the responsibility which is known to the plurality of GPUs. The method including generating information regarding a piece of geometry with respect to a first screen region for which a first GPU has a first division of responsibility, while rendering the piece of geometry at a second GPU for an image. The method including rendering the piece of geometry at the first GPU using the information.
