-Use the ``time_limit`` parameter to set a time limit (seconds). Use ``throttle_frame_rate`` to throttle the stream's frame rate (frames per second) to a slower pace than the Sketch's actual draw frame rate. The ``scale`` parameter is a scaling factor that can adjust the portal height and width. The ``quality`` parameter sets the JPEG quality factor (default 75) for the stream, which must be between 1 (worst) and 100 (best). If the portal causes the Sketch's frame rate to drop, try adjusting the portal's throttle frame rate, quality, and scale.
+Use the ``time_limit`` parameter to set a time limit (seconds). Use ``throttle_frame_rate`` to throttle the stream's frame rate (frames per second) to a slower pace than the Sketch's actual draw frame rate. By default, ``throttle_frame_rate`` is set to 30, which is half of the Sketch's default draw frame rate of 60 frames per second. Set this parameter to ``None`` to disable throttling. The ``scale`` parameter is a scaling factor that can adjust the portal height and width. The ``quality`` parameter sets the JPEG quality factor (default 75) for the stream, which must be between 1 (worst) and 100 (best). If the portal causes the Sketch's frame rate to drop, try adjusting the portal's throttle frame rate, quality, and scale.
 
 If your Sketch has a ``post_draw()`` method, use the ``hook_post_draw`` parameter to make this function run after ``post_draw()`` instead of ``draw()``. This is important when using Processing libraries that support ``post_draw()`` such as Camera3D or ColorBlindness.
