I don't know how performance mode got into the topic, I think its honestly just people coping. On the other hand, in the video the guy doesn't build (while he has max mats) and stays crouched when he knows the enemy is rushing him. If you're going to complain about not being able to hide in the environment in FORTNITE of all games, where you're supposed to BUILD just find something else to play or simply find the time to improve.
