    Only on cars with high caster setting or in general?

    I only use the Porsche GT3 and have not made any modifications. Whether it's high or low speed, when the steering wheel rotates close to 180 degrees, I start to struggle because my base torque is 16NM. When the steering wheel is in a small turning range, the force is actually very small. As the angle increases, the required force becomes stronger, and it does not decrease due to any state of the car.
    Of course, there are also files that will not encounter this situation, such as JP's fullFFBv7, which is somewhat similar to the default. When the angle is too large, the force will decrease sharply.

    I've tested Porsche 911 GT3 (Gen 1!! o_O) and it's all good on my side, at 10Km/h no change in forces until I hit the car's steering lock, just over 180º.

    without knowing which files you have tested, there shouldn’t be a great gain in force at stationary, but you should feel the caster working against you.

    In motion there will be grip loading and some gforce loading depending on speed, but I can’t imagine to many instances that you would steer more than 90 degrees especially at high speed .
    Hairpins etc can be a physical effort as the front tire is loaded with all the weight of the vehicle and grip reduction is t really a factor at this point .

    But in normal condition in normal radius turns the load should build up until the grip is falling away and also if you overturn the wheel , there should be a subtle change in pressure and you should feel the point that the angle of the tire is over it’s useful limit .

    If the loads are too strong , your gain might be too high . Or depending on file , you may benefit from increasing static force reduction.

    About steering vibrations...
    My guess is control loop is not tight enough to ensure a correct/well behavioured PID control system, specially when we want high forces near the center. I maybe wrong.
    It stop worrying me as it has no impact with the hands on the wheel, where I tend to keep then while I'm driving :whistle:... just a light touch with a finger tip and the wheel goes nowhere.

    DK V500 etc.
    I mean as the steering increases, the resistance only increases and there is no sign of a decrease. For example, in the hairpin, when the car is not enough to pass through the corner, I can no longer turn the steering wheel.
    I quickly tried several files, and over 3/5 of them were in this situation. I will try more according to the reply above. Because I have always used default+ before, usually the resistance decreases after turning 120 degrees, so I still need time to try and adapt in order to better understand the problem.:)

    I don't know your base and I don't know your in-game and base settings. I think it could be a problem with your general settings. What is your setting on the base in the steering area? What kind of steering angle do you use on the cars? Try to adapt your settings to the files;)

    This feels good for me, too.
    There is little virbating in straights not like wheels have 1 kg/wheel imbalance.
    Only I need is a bit more curb and off track feeling.

    My settings are tm cp all in 100% and 540° with sparco R383 rim (33 cm).

    In-game settings
    gain 60
    low force boost 25
    fx 55
    damping 10

    This works in Finland, too.

    Maybe someday I try to setup Daniel's V500 to fit my hands.

    Do you mean, at the start of the race before T1?
    After T1, it's normal, it's called "flatspot" :D
    Really, your descrition looks like flatspots. Check if this is the case.

    Try changing this... (as a matter of fact, I've already changed to compensate for a change I've made in my new/test file). You should have "0.2", go from there.
    Code:
    (details_contructor_smooth (* 0.3 (smooth details_contructor 0.07))) #was 0.2

    As I mentioned above, the in-game and base settings are very important and should be adjusted to the different customs otherwise you will have problems

    I don't think he means the flat spot because he doesn't have any problems with it with Default+. And the defaults are very aggressive in this respect, after a short time you only feel the flat spot and a lot of other FFB is lost - everything is covered up. That's why I left the flat spot at 0, even with this setting it is still there but within a reasonable range

    Yeah !! So nice :) Happy to share with you. Just to tell you, since the latest file, i just modified it in order to increase Front and Rear Stretch feel (around 3 for each value). It is even better feeling when turning or brake. Have a nice moment with your steering wheel... and don't forget your wife :) :)

    Hi Joaquim. Yes i agree, i have tested Default and Default+... quite desapointed. Let's continue with our FFB custom. Hope you feel R12 great into your hands :)

    Hi ! I think this is "velocity_res_offset" (how much resustance at velocity 0)
    I have a T818 too and produced a specific file for it. You can check if you want. You have my specific recommandations in the bottom in the file. Cheers

    That vibration starts from pit leaving in Daniel's file.:D

    Yours v7 file works fine with small vibration.

    And I am using that v7 file.

    That 0.3 feels better.

    My settings are now:
    gain 60
    lfb 25
    fx 50
    damping 5

    Sorry, I didn't provide a complete description of my settings yesterday. At that time, I just wanted to confirm that situation. If it was really a special feature, I would accept it. If it is my case, I will try to find the problem on my device. My base is MOZA R16, because I know that the driver/firmware of MOZA is not very good, so my main purpose is to determine if it is a problem with my R16.
    In game: 62-0-20-0
    I tried files 5-7 V500, although the strength was different, the situation was the same.
    Moza Pithouse:
    Max steering angle 1080
    road sensitivity 9 (I don't like 100Hz)
    Game FFB Intensity 100
    Max Wheel Speed 30% & 100%
    Max Output torque limit 80%
    Natural Inertia 100%
    Others 0/OFF
    Describe: In fact, the feel of the steering wheel in the central area is very good (-90 to 90). But when I try to rotate more than 90 degrees, I start to feel a noticeable elastic resistance that increases with the angle. It is almost unaffected by the actual condition of the vehicle, even if I can feel the vehicle lose control and another normal force is changing, but this elastic resistance always exists. When I want to pass through a hairpin, I usually need to turn it 150-180 degrees, and then I find that the resistance is too strong for me to turn the steering wheel.
    Then I realized that it seemed to only affect the angle, and when I rotated less than 90 degrees, it was weaker, so I couldn't feel it. When the rotation exceeds 90 degrees, I can feel it. When the rotation approaches 180 degrees, it is too large and almost uses the maximum torque. This is so strange, that's why I wanted to determine if it was a problem with the ffb profile or my R16.
    Then I used files from several others and found that only two or three were not like this. When the car is stationary, it will not be like this. At 70km/h in first gear, this situation will occur.
    I took two screenshots and am not sure if they are useful. Above is V500, below is JP FullFFB V7.
    (Actually, before that, I made a video specifically for players in my country yesterday, introducing how to use custom ffb profiles and how to download files from DanielKart and others. As a result, I first encountered an unknown problem myself.:D)

    My country's players are particularly sensitive to one thing, which is that when their hands leave the steering wheel, the steering wheel will vibrate violently, which we all call "death swing".
    When I use default, it usually appears after 3-10 seconds. When I use default+, it usually only takes 0.5-2 seconds.
    It doesn't really matter to me.
    Yesterday when I used V500, the "death swing" disappeared, and when I used JP V7, it reappeared.
    I have found that all profiles have a strong centring force, which causes the steering wheel to sway more and more uncontrollably when the hand leaves the steering wheel. However, when using V500, although the centering force around 180 degrees is particularly strong, when the steering wheel is close to the center position, this force is almost eliminated and will not cause the steering wheel to rotate to the other side, thus avoiding the occurrence of "dead swing"

    Well recognized one of the main reasons why the defaults are not an option for me. And this swing will only get worse the more in-game dampening you use
