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. | As you can see, rendering takes place only after every rendering command has been issued.
