1. A head-mountable display system, comprising:
a head-mountable display device, comprising:
a housing;
a display panel within the housing; and
one or more eye tracking units configured to obtain eye tracking data;
an eye tracking module configured to identify a change in a current gaze location, based on the eye tracking data;
an eye prediction module configured to generate a predicted future gaze location based on the change; and
processing circuitry configured to render, for display by the display panel, a predictive foveated display image frame based on the predicted future gaze location, wherein the display panel is configured to display, while the processing circuitry renders the predictive foveated display image frame, a current foveated display image frame based on the current gaze location.
