With the removal of skills in Fallout 4, Perception now directly affects accuracy in V.A.T.S., lockpicking, and stealing attempts.
The main difference from Fallout 3 and Fallout New Vegas is that perception no longer affects the distance at which enemies appear on the player character's compass. Enemies do not appear on the compass in Fallout 4 unless they are looking for the player character (Caution in sneak mode) or are fighting the player character (Danger in sneak mode).
