A method and apparatus for displaying composite images, as viewed from a relatively stationary eye point, including a moving target image of relatively small field-of-view overlaid on a background image of relatively large field-of-view, by generating a background image video stream of image data for the background image; updating the background image video stream at a zero or low data update-rate; generating a target image video stream of image data for the target image; updating the target image video stream at a relatively high data update-rate; combining the background and target image video streams to produce a combined video stream; and feeding the combined video stream to a display system for displaying the composite images. The described preferred embodiment is a simulator, wherein the display system includes a plurality of projectors each projecting a predetermined section of the composite image including the background of the respective section, and the portion of the target in the respective section.
