System and method for controlling the operation of a work vehicle to provide improved responsiveness when commanding implement movement

A method for controlling the operation of a work vehicle includes initially controlling an operation of an implement actuator of the vehicle based on operator inputs received from an input device while a load sensing system of the vehicle is operable to adjust an output of an associated pump. The method also includes receiving an input providing an indication that an implement-based movement operation is to be performed and deactivating the load sensing system in response to the indication that the implement-based movement operation is to be performed. In addition, the method includes controlling the operation of the implement actuator based on further operator inputs received from the input device to perform the implement-based movement operation while the load sensing system is deactivated.
