In one example, a streaming server or a client device may measure an end-to-end time for a streaming operation in real time. The streaming server may store an input time associated with a user input and a frame presentation time associated with the frame output. The streaming server automatically may correlate the user input to the frame output generated at the streaming server in a frame generation process. The streaming server may calculate an end-to-end time based on the input time and the frame presentation time. The streaming server may adjust the frame generation process based on the end-to-end time.
