The experiment showed that after deleting more than 1000 friends and clearing the mailbox, the interface and games worked faster. Leonard noted:
Input lag has decreased, shots in Halo are registered faster, and aiming has become much more responsive.
He suggests that system processes constantly monitor the activity of a large number of friends, which consumes console resources.
Similar problems have occurred before: when updating Windows 10 for Xbox One, mass messages from friends slowed down the system. Leonard advises using the "follow" function instead of adding friends, which is easier on the console. Despite the lack of official confirmation from Microsoft, the player claims that deleting unnecessary data eliminated even bugs with freezing when reconnecting to matches.
