Abstract
Methods and devices for presenting a virtual reality image may include rendering at least one image frame received from an application for a virtual reality image for display on a display device. The methods and devices may include receiving a selection of one of a plurality of tear thresholds that define conditions for tearing in a displayed image. The methods and devices may include determining whether the rendered frame is received prior to the selected one of the plurality of tear thresholds, wherein the selected one of the plurality of tear thresholds occurs after a frame timing event that corresponds to a deadline for initiating display of a new frame. The methods and device may include communicating the rendered image frame to the display device for presentation on the display device when the rendered frame is received prior to the selected one of the plurality of tear thresholds.
