My problem with FFB is that the forces are enhanced by the steering wheel, which is not realistic. IRL, as far as I know, the forces coming through your steering wheel are the forces coming from the wheels, suspension, tires etc. In certain racing cars, which have power steering, these forces are muted somehow. In a sim the forces coming from the sim are transferred to the steering wheel which enhances the forces significantly >>> read: the torque of the steering wheel (DD wheels are in that regard super unrealistic). IRL when you are drifting and let go of your steering wheel, the steering wheel will align itself automatically (is this what
@Scaff's chart is about?) but you can easily stop the wheel from turning (forces, not the speed of the turning wheel because that could be potentially dangerous). When you are drifting in a sim, the steering wheel wants to align itself as well but the forces when doing so are super unrealistic and super enhanced by the electronics of the wheel and the torque of the wheel's motor.
And that is what I hate about the FFB and say it is crap and unrealistic.
The real forces of the wheels, suspension and what not should be transferred to the steering wheel without being enhanced that the wheel. You could argue that this is already happening but you are still able to so in the FFB settings but that is one of my problems. The FFB coming through the steering wheel are enhanced in the settings (if you turn the settings to the maximum) AND by the steering wheel itself.
Not to mention the FFB coming through the wheel that is felt through the suspension, chassis etc of a real car and not the steering wheel.
A few years ago, a friend invited me to try his new AccuForce in Assetto Corsa. When I started talking about the FFB and how I feel about it we started to experiment with the FFB settings in SimCommander. He followed my instructions of what I think should be felt through the steering wheel and what not and how you should feel these forces and guess what, his lap times improved from the get go. So I guess there has to be some truth to what I'm saying.
It is not easy to explain what I mean but I hope you all understand what I'm trying to say. And it is my personal opinion and doesn't mean that it is correct.
I just read this in the Fanatec DD steering wheel thread:
There is simply no situation in normal use where the motor would be delivering full power ...
A steering wheel in a real car doesn't have a motor that delivers
extra, unrealistic power.
And the forces coming through the steering wheel of every single car IRL is different and feels differently. This is not the case in sim racing. It feels more and less the same in every car you are racing.
