The normal gear retracts faster in real life when supplied by on board hydraulics.
This is the gear of a 777-200 as it "flattens out" just before retraction.
777-300ER has another hydraulic strut forward of the gear, which locks the main landing gear "flat" during take-off rotation, thus the aircraft rotates off the aft axel, thus lower take-off speeds and provides better tail clearance at rotation.
