    I too noticed in races with the Formula Renault 3,5 that the flat spots can get better after a few laps. Just make sure not to lock up again.

    I have issue with ffb rattling. Not with flat spots. I understand why they are there but I've already explained why I don't like the rattle.

    I'm starting to remember why rf2 crowd has a bad reputation...

    I'm getting linear response with wheelcheck. Enough to tell the wheel is in good shape. It is not magic! Everything fails eventually some day. I'm gonna take the necessary steps to push that date into the future as much as I can and reducing wheel rattle is one of the steps.

    Why the condescending tone anyways?

    Not filtering out large changes. Filtering out high frequency noise.

    Anyways, I'm done here. I've explained my point several times and some people are getting pretty triggered for reasons I don't care about.

    What kind of response did you think you would get?

    You seemingly flat out ignore all of the insightfull posts Lazza has written, then you proclaim to know exactly
    how it works by saying it's an easy fix. Then in the same post you say you don't really know how it works.

    Really? What did you expect? And it's the rF2 crowd who's wrong? What about people insisting on rF2 being or
    doing things which it it very much isn't, or downright doesn't work the way you 'think' it does, even when presented
    with insightful/truthful and sometimes downright factual explanations by people who spent a lot of time on those
    subjects, including devs?

    Then for the THIRD time turn FFB Smoothing to a level that works for you :) problem solved.

    There are mods in rF2 where flatspots aren't so much pronounced as in most ISI tyres. For me it's no problem with physics engine but in tyres modelling. I think that most ISI tyres are over-sensitive (purely subjective) in this regard. Is it correct or not? Who knows. When we'll have more sims that simulates flatspots we can compare then.

    Assetto corsa and AMS do, the effect is WAAAYYY less pronounced. Which is more accurate? I dunno.

    In pretty sure rF2 implementation is the most accurate available today.

    He asked the question he didn't state anything :)

    I know what a low pass filter is, and it's not what you want. You're getting high frequency FFB the whole time without issue, it's the amplitude of flatspots, kerbs, grass that cause the rattle.

    I don't know why from your first post in here you were playing the victim. People disagreeing with you doesn't mean they're attacking you, and especially when it's not you they've been arguing with (as was the case early on).

    I just wish you'd read and understand, and acknowledge, the arguments you're then ignoring. There's no flatspotting FFB code, end of. Makes the simple solution pretty difficult.

    @Juergen-BY he was asking which one is more accurate. Your 'no' implied he was suggesting one was. It's a subtle distinction, but most native English speakers would see it that way. Just for info.

    language barrier obviously, he asked "which is more accurate?" in the meaning of - "RF2, AC or AMS?", therefore "No, it's not" is not an answer :) no worries though.

    Edit: as Lazza said!

    Those sims are not using a physical tire model, so I'm 90% sure rF2 is closer to simulating a real flatspot. Besides, all testimony I hear from real drivers is that a flatspot almost rattles the teeth fillings out of you. Nico Rosberg had to pit in lap 1 because of this in Sochi 2014. If anything we don't get the full effect because our sim wheels are too weak.

    And I really would like to know if you can manage a flatspot to fade away after awhile in rf2. I tried it a few times but without success. Might have tried it with the wrong tire compounds?

    I have had mixed results in league races in the past. A flatspot where you've made a mistake too many but isn't a very big deal yet (vibrating wheel), I could ease it up a bit but never get away completely. Which is fine, if you manage your braking and such, you can finish the race, and that is the thing which I like a lot. You can still manage it in such a way to make it do as little damage to laptimes as possible, but it isn't very easy to do.

    However, i've also had cases where in the first lap I outbraked myself in a fight, and a couple laps later the 'incidental' lockup occured. Now if you have one too many you are already looking at a more severe flatspot (teeth rattling), this only needs little to turn it in a 'messing up the balance' kind of flatspot. This severe flatspot, no way you can get rid of that and doing the extra pitstop actually is the only solution I personally see in that case.

    In both cases, manage your brakes. When you indeed have a flatspot, the nature of it makes it more prone to additional ones, on that exact same spot. So it is easier to make it worse, than ride it out and have it ease up on you a bit.

    Fun little detail though. Since I've had my OSW, I have yet to deal with a full blown severe flatspot. It is easier to feel when you're on the verge of/actually locking up and take precautions to prevent a 'big one'. If I then see someone advising 11% STM for a Logitech 920, I'm wondering if people are drowning out all detail they can for some straight line feel.

    But in F1 is it about force or grip? A bird poop in the wrong place can cost those cars seconds lol

    This is something I've heard commentators mention loads of times, that when you get a flat spot you inadvertently "find" it again the next time you brake hard, I struggled to notice it doing this in RF2 in the early days but I swear when the CPM updates started coming out this suddenly appeared (maybe a placebo of course and always there!), either way I grinned at it's awesomeness :)

    Are race drivers prone to bad teeth? I didn't get a filling until I was in my mid forties!

    As far as my own experience has shown ..... the flatspot (effect) gets weaker, if you drive smoothly. But it doesn't fades away completely.

    I'm not sure that claim can be substantiated since there's no empirical evidence. The best we can do is superficial observation and that, unfortunately, means it becomes totally subjective. Hence the original dilemma of the OP.
