You certainly feel a rotary turbulance before you can see its effect on the plane. Are you telling me that if you get a "slap" on one of your wings and you immediately counter yoke you only do it after you actually see the horizon tilt or instruments indicate it? I know I don't because I would and did react to wings tilting because of sudden turbulance while looking at the map.
It is true that in the clouds you won't know which way is up or whether you are in a turn or not. G's can play tricks on you, fair enough. But whatever conditions you are in you will feel the thumps and react automatically.
Also instruments have delays, they help with what you cannot see or feel., but your body is still faster if you can "feel" the changes. For me, this is also why taking off in a real plane is easier as I can feel the changes and counter react before they are big enough for the eye to see.
