Map responsiveness

There is plenty of information on how fast is Edge 1050 when it comes to its responsiveness to touching the screen, yet I couldn't find any info how long does it take the map screen to update after a turn (track up map orientation). It takes 2-5 sec for my old Edge 830 to update a map view after turning, even when no navigation is active ("always on display" course, though). Is Edge 1050 any better?
