Yeah, definitely need (un-biasedTM) user-reviews, not sales pitches. I can imagine some improvement coming from the controller-processing improvements and the Static Torque Reduction seems like a useful setting but, I feel like the overall tangible improvement in FFB is still likely to be fairly subtle, especially when weighed against the overall cost to upgrade again.
Still, interesting development to keep an eye on and see how this DD-line stacks up against the Fanatec Podium series.
Of course, if game developers sell us FFB that is dumbed down and sold as being "more realistic", how useful is a smoother ffb-system really going to be(?)
