Abstract: The disclosure provides features or schemes that improve a user's experience with an interactive computer product by reducing latency through late latching and late warping. The late warping can be applied by imaging hardware based on late latch inputs and is applicable for both local and cloud computing environments. In one aspect, the disclosure provides a method of operating an imaging system employing late latching and late warping. In one example the method of operating an imaging system includes: (1) rendering a rendered image based on a user input from an input device and scene data from an application engine, (2) obtaining a late latch input from the input device, (3) rendering, employing imaging hardware, a warped image by late warping at least a portion of the rendered image based on the late latch input, and (4) updating state information in the application engine with late latch and warp information.
