Not just for show! Actually saves a lot of fuel even at flank speed on long distances! Though make sure that when submerged and you need hard evasive action you have them both operating!
By the way, when ordering periscope depth, do you also stand behind the ladder at the device with the schußwinkel placque? I do, saves crew moving through youbwhen they come down. No mod to have crew back away when you are near them or want to walk past them afaik.
Ah well... The only way is through. Hehehe.
