It's a bit better in rF2.
In my opinion there are 2 factors:
- The inertia moment is higher on rF2. When you turn the steering is more sensitive to the axial displacement. Just a little, but it's noticiable.
- The surface of the tracks (official content of course). They are more complex than AMS.
Anyway, both FFB are superb, in my opinion by far the best in the sim market.
