Abstract
A system for producing image frames for display at display device. The system includes graphics processing units including first graphics processing unit and second graphics processing unit that are communicably coupled to each other and pose-tracking means. Second graphics processing unit is configured to: process pose-tracking data, to determine device pose and velocity and/or acceleration with which device pose is changing; execute rendering application(s) to generate framebuffer data corresponding to image frame; and send, to first graphics processing unit, framebuffer data and information indicative of device pose and velocity and/or acceleration. First graphics processing unit is configured to: execute first compositing application to post-process framebuffer data, based at least on said information; and drive light source(s) using post-processed framebuffer data to display image frame.
