Well, I just tested it. With Ford Falcon it is very easy to see what is going on. BTW, if you click with right mouse button on slider, you'll get "What's this" box. Clicking on it, you'll get explaination of what this slider does. It is very simple, with 100% you get direct contact with FFB, anything less loses contact with FFB, and introduces slack, which behaves very much like a dead zone, only it isn't dead zone, but just a lack of sensitivity. 50% isn't linear, 100% is linear, anything else is less linear. |

Then you have to ask yourself... why did Logitech make the default 50%? Two people have told you that 50% = linear. A Google search would turn up the same answer. You can go with that, or ignore the facts and just muddle about on your own. You should certainly consider the possibility that you've jacked some other setting up so much that what you're "feeling" with the slider at something other than 50% is just a compensation. |

You guys are right, thanks. Steering wheel on the "Options" screen clearly shows that you are right, thanks. But, this isn't that easy. 100% drive so beautifully, and this is the ultimate judge. But, thanks, you are right, somewhere else is the problem. Well, I already checked absolutely everything, and the only thing that is left is the calibration process, which I started to fiddle with. Here somewhere I must be getting slack. Thanks again, : ). |

Ok, I found it. With calibration everything is ok, calibration is simple process, and it doesn't affect FFB significantly (thanks God). Regarding removing slack, I did the same like when I've put Overall at 143%, only this time I left Overall (O) at 100%, and lowered Spring (S), Damper (D) and Centering Spring (CS) equally. I tested a lot today, so I am too tired to find "the right" value for S, D and CS today (I'll resume tomorow). It is somewhere between 58 and 70%. I tested 50-56%, and tried 57%, and it is above those. It isn't 57%, so the difference between O and S/D/CS isn't the same like before, but it is close. Regarding how this behaves (so far), excelently. I am more than pleased. It behaves just like it should. |

Yes, it should be 50%. Centering Spring should be 50% (and it is responsible for slack). Spring and Damper is per individual preference, as long as they are equal. One can even run them at 0% if he wants "pure" forces. This is for Overall = 100% and natural FOV. I don't know if Centering Spring should be other than 50% if Overall isn't 100% and FOV isn't natural. Maybe I'll test this some day. |

Hm, it turned out that it isn't just any Spring and Damper (equal) the best. Too low, too spring, too high, too dampy. It turned out that the best is 71%. Well, this isn't good. Why? Because if I put 100/71/71/50, then 50 is 71% of 71, which means that Spring and Damper are equaly distanced from Overall, as Centering Spring is from Sping and Damper. Not good. Well, too late today, I'll have to resolve this puzzle some other day, : ). |

Since 100/100/100/100 works well if sensitivity is 100%, I wouldn't be surprised if all this doesn't have something with the position of sensitivity. |

Hm, Spring and Damper at 71% work well with Centering Spring at 100%. I'll see if there is more to it. |

I'll see if there is more to it. Hm, interestingly, 143 to 100 is in similar correlation as 71 to 50, or as 100 to 71. |
