A benchmark test system captures and records root, or input, behavior from a user input device as one or more time-displaced samples of input. The system also separately captures and records the canvas, or visual, behavior of a user interface in response to the captured input as a series of time-displaced image frames. The image frames are analyzed for visual prompts occurring responsive to the input, and parameters of the image frames are determined. A parametric difference between corresponding ones of the root events and canvas responses is thereby computed, in order to determine a degree of visual responsiveness for the user interface software respective to the root input.
