 ## ``--only-generate`` (Server Mode Only)
 If you run MCPI-Reborn with ``--only-generate``, it will immediately exit once world generation has completed. This is mainly used for automatically testing MCPI-Reborn.
+
+## ``--benchmark`` (Client Mode Only)
+If you run MCPI-Reborn with ``--benchmark``, it will enter a simple benchmark mode. This means automatically loading a newly generated world, then rotating the camera for a period of time. When it has finished, it will then exit and print the average FPS while the world was loaded. In this mode, all user input is blocked. However you can still modify rendering settings by changing feature flags.
+
+The world used will always be re-created on start and uses a hard-coded seed.
