The panel-selection switches don’t change the underlying image settings so the OP is not turning off images settings that will be turned on later, they are merely not burdening the computer with rendering those compute-intensive settings.
Sorry Steve, but I don't understand this comment. Turning the panel switch off after applying lens corrections via default settings WILL change the rendered preview back to the "lens corrections not yet applied" position. So if you can't see the effect of these "underlying image settings", I don't understand the point of making them then immediately hiding them again. What am I missing or failing to understand?
