Regarding everything, you are doing something wrongly. I am not doing it, so I don't know what you are doing wrongly (generally I tend to avoid doing things wrongly). You are measuring something, you don't know what exactly. Somebody told you that this is it, and you accept this lightly. It is your problem, not mine. If everybody else also accepts this (lightly), this is also everybodyelse's problem, but also NOT mine. I wrote that clipping isn't JUST a constant force in Force Fedback. This means that it IS a constant force, but there is more to it. Mario |

Where you can have problems: You got to set hight of screen ("DrivingVanishY"), latency ("cockpitLookDeadZone") and FOV. FFB signal is something like hi-fi, you got to have clean, undisturbed signal. You got to get rid of compression-like things, other noise and delays. For example, iRacing's AA and AF works like a compression (I presume). Use video card AA and AF. Use no-limit fps. And things like that. Use USB port that doesn't share resources with other things. I disable all I/O ports that I don't need. And things like that. Dirtiness, compression and delays affect FFB. Regarding how much it approaches real life. The way I am using FFB is the standard made by inventors and productors of FFB and FFB devices. They should know what they are doing, and it is advisable, if you are using FFB devices, to use them per their standard. If you don't use them like that, you can expect to have below average results. I don't get constant clipping, if I would drive my wheel with the strongest force it can produce, I wouldn't be able to drive a car, and I am getting 1:57 at Suzuka, with fixed Corvette setup. Even more, I am just testing FFB, and when you are testing FFB your last lap should be driven like your first lap, otherwise you lose reference points, and you musn't improve your driving line, or anything, the improvement in time must be solely because of the improvement of FFB. Of course, I cannot resist to improve on my driving line a bit, but this definitely isn't some major effort, and I do have some room to improve times, when I finaly set the FFB correctly. Mario |

Sorry Mario, but the whole FFB thing is subjective at best, even on a
$15000 simulator. The 2D screen, the shaking, etc. are nothing like what is felt in a real car so my thought is set it the way that "feels" good and go play. Some of the fastest sim drivers in the world can beat you with a joystick and no FFB, my thought is you are wasteing a lot of time trying to achieve the unachievable.. it's a game after all, just play it.

Yes, that is your thought. My thought is that this isn't so. Just like Ken said, you got to have just the right amount of damping. The same goes for everything else. For now, it really looks like all four things have to be on the same value. But, there also problems regarding some other things (lag, FOV, dirty USB signal, and so on). So, this is my thought, and my discussions are for people who are thinking like me. So far, it looks like it works (I am driving pretty well with my setup, much better than with iRacing's way to set up FFB, and I am much more pleased with what kind of FFB I am getting). The big problem is in iRacing (and the sim community). It looks like initially they were pretty confused about FFB, and overhelmed with all those numbers, and couldn't find the right way, so they created some kind of FFB alchemy. Good example is the question od damping, where they support the way that without damping you get the "pure" signal (which ISN'T the "right" signal, just like, now suddenly shy, Ken explained). Then they have put 75% damping. This alchemy just puts more confusion. Why don't they leave people to do this for themselves (if THEIR view ALSO is that this is subjective). Well, I am working on it, and trying to find the answers. Mario |

Ken is not being shy, he just doesn't have anything new to add. ;-)
Have found nothing that clarifies if damping in FFB settings is applied the same way as it is in control systems or how it is used (or not used) by the software. Don't have any way of verifying if the suggested settings are correct. Unless someone has come up with a way of measuring the forces at the wheel and comparing them to the forces being requested by the software then whether or not the forces are correct for given settings will be subjective. |

You cannot do this, because this thing is dynamic, and it works on a feedback, differnt feed, different output. But, once the "control" settings are established, you CAN do one thing. You can distinguish *patterns* produced by incorrect settings (in comparission to the correct settings), and produce a tool which can help you to minimaze/eliminate those patterns, and thus help you establish more correct settings more easily.
