Actually I think it is the other way around. rF1 with RealFeel and rF2 deliver raw rack forces to the wheel whereas AC does some sort of canned stuff like rF1 (without RealFeel) did. In AC they are only delivering the forces they think you should feel. In RealLife you get raw rack forces but they are severely dampened by the power steering, linkage, rack bushings, ect ect. rF2 can sort of simulate some dampening via the smoothing levels and they (ISI devs) could probably add a little more dampening if they wanted, to further simulate power steering. But as you said, we lack feedback in other areas (gforces) so any extra data is welcome.
