System and method for efficient multi-gpu rendering of geometry by performing geometry analysis before rendering

A computer system comprising:

• a processor;
• memory coupled to the processor and having stored therein instructions that, if executed by the computer system, cause the computer system to execute a method for graphics processing, comprising:
• rendering graphics for an application using a plurality of graphics processing units (GPUs);
• dividing responsibility for processing a plurality of pieces of geometry of an image frame during an analysis pre-pass phase of rendering between the plurality of GPUs, wherein each of the plurality of pieces of geometry is assigned to a corresponding GPU;
• determining in the analysis pre-pass phase overlap of each the plurality of pieces of geometry with each of a plurality of screen regions;
• generating information at the plurality of GPUs regarding the plurality of pieces of geometry and their relations to the plurality of screen regions based on the overlap of each the plurality of pieces of geometry with each of the plurality of screen regions;
• and
• assigning the plurality of screen regions to the plurality of GPUs based on the information for purposes of rendering the plurality of pieces of geometry during a subsequent phase of rendering.
