The following picture illustrates the classic processing model used in [[VR applications]]:

*I = user input, S = simulation, R = rendering command, G = rendering of graphics, V = scanout, | = Vsync
As you can see, rendering takes place only after every rendering command has been issued. This introduces unnecessary latency and simultaneously suggests a simple solution. If GPU buffering is prevented, rendering can start as soon as the first command is issued, thus reducing 16ms of latency.
