---Enables or disables flight path benchmark mode. When benchmark mode is enabled, the next taxi flight the player takes will behave differently: camera movement is disabled and players/creatures/objects below the flight path will not be shown (allowing for consistent test conditions). After the flight, framerate statistics will be printed in the chat window and benchmark mode will be automatically disabled.
