Automobilista 2 Custom Force Feedback - Overview & Recommendations

Only one question ... how the damping influence this situation?? How set the damping slider in game?? Karsten use if i don't mistake 0.25 ... but even if your value is 0 ... what happens on your base if you had to raise it a little bit up to a maximum of 25 ??

 

Hi!
I´m on currently on vacation, will test with my DD1 when I get back
Did some testing a few days ago with Karsten´s latest file, as well as Stakanov´s and your files before you started the latest round of tweaking. At that point I preferred Karsten´s file, but I´m looking forward to test your improvements later on.
By the way, what do you mean by ´swinging´? I speak a little German, so feel free to describe the swinging feeling in German if you want

 

Thanks @torsteinvh for this info, but if you prefer karsten's file on Fanatec DD1 (which I also share on the low end) using the basic settings (or just slight personal changes) it means that, these oscillations that Daniel lives to the point of upsetting the files, you don't have??

@Danielkart sure there is no other way to stabilize your DD1 steering wheel??

Because if there is a way for the basic settings to work everything would be easier .... and the solution was already in front of our eyes

 

If "Swinging" equals Oscillation, then some Damping should solve that. DD-wheels should have plenty of Dynamic range to provide both, superb detail with total oscillation control through Damping and/or Friction, imo.

Zero damping / zero friction with dd-wheels will likely produce oscillation, no matter the title. "Overshoot" is an inherent characteristic of the ffb servo system, not necessarily a flaw in the game ffb. Exceptions may exist due to generous amounts of Gyro / Damping applied to the game ffb signal but, those can usually be controlled one way or another (ffb preset / ffb mode / manual profile editing / use of direct to servo effects).

 

Not only do I share this information from you DD users but it is very useful ... because I also like karsten's original base and my file (even if it seems modified on many things) is not very different from the original and I share it (except a couple of voices) settings and code ... would seem to really like the mid-low range ... in the DD-High range some like it to others it feels heavy along the fast corners ... I think I managed to reach the goal of this aspect and thanks to Daniel for help me ... but if I can recover even the strange sensations of Daniel without further upsetting the file I would be happier ... I don't have the presumption of making a universal file for everyone but I like to play with the FFB trying to reach the goal ... we wait for Daniel to clarify better this "swinging effect" as soon as he can answer....

 

I mean the oscillating or extreme back and forth movement of the wheel

 

Unfortunately, when I take Stakanov's Custom, I have this extreme oscillation from about 8Nm. If I take karstens custom I have to be a bodybuilder as well. It gets so brutally heavy and hard with a dd1. Other people with a dd1 also confirm this to me. I don't like the damping in the game because it also takes away ffb from me. And in addition, the damping also increases the oscillation, just like the lfb in the game. That's why I always stayed with the 5.01 original, everything after that made it even stronger or worse. Maybe it's a problem with dd1 and dd2 bases, I don't know. But I know that with the 5.01 original and certain adjustments I have a ffb feeling like god in heaven

 

I would be very grateful if a dd1 or dd2 user could bring me a solution

 

How much gain are you using in-game? Why not just use lower gain if it is too strong?

 

@Danielkart if some feel it and others don't, you will surely find a solution somewhere with DD friends ... the fact remains, however, that having explored so many roads has served me a lot

For now , when you can, try this with your advice ... i think it is much smoother and more manageable ...

power_steering_angle slightly higher than 0.15

 

Hello Karsten
I use 60Gain in game. No, I don't want to go down because I'll lose ffb then. I described that on page 241 with the gain. But thanks, I have my own custom file, but it would have been nice if yours or Stakanov's file would work for everyone
regards

 

@Karsten Hvidberg the idea of wanting to bring my file closer to @Danielkart 's needs is mine, he is fine with his file, he was just trying to make this possible for me and my file ... and then is him that help me!!!
When others with DD1 said they didn't have Daniel's problems then I hoped there was a simpler solution.

Why do I insist or pursue this need?
Because I suspect that by solving the oscillations on DD at high GAIN we can improve something on the whole range of steering wheels ... we will see, for sure I am experimenting with solutions and values out of the ordinary.

 

You will not lose FFB going to lower gain. On the contrary you will get more headroom for the downforce gain as well as make it clip less in the file, possibly.

 

i’ve not had time to keep up with the latest experiments, but i’ve been trying to find a solution for hands off the wheel oscillation for quite some time.
as i think it’s the number one problem. everything else is just a matter of taste.

It became a problem with the 5.0 series of file’s, the main value that introduced the oscillation was the higher understeer scale ,
but lowering that now doesn’t feel good now .
it generally comes on in severity with increased speed ( like above 200kph) and even more so with high downforce cars.
what seems to be happening just from a feeling point of view is that the centre is tightening or becoming narrow as the speed builds.
i also feel it’s something to do with the way LFB is being utilised. as one way of reducing the effect of the oscillation wave , (which you can see in telemetry, ) is to lower the Lfb strength (in file ) to low levels. which makes the lfb curve a gentle slope but this also comes at a cost of sensations.
Another band aid fix is to use a older understeer relax .

so perhaps it’s something that needs to be altered in the deeper code that controls how the LFB behaves at higher velocity. and also a look at what can be done in terms of relaxation of understeer and centre.

 

@Karsten Hvidberg, @Stakanov and @Danielkart.
I like all your files, the reason I preferred Karsten´s is that that was the one that gave me the best feedback on when I was pushing (too) hard and the front tires were about to lose grip.
The other files were pretty close, and I could probably live happily with either one. All three are very, very good I guess this comes down to personal preference as well. I like to feel the front tires losing grip above other feedback, so Karsten´s file provided me with that.
I have oscillations on all three files, I have just learned to live with it and not let go of the wheel.
Settings currently are in-game gain at 50, LFB at 10, damping at 10. Fanatec base settings gain at 75, damping at 30. No other filters.
On my DD1 in game damping actually make the oscillations worse, that´s why I run damping at the wheel base as well. Need to experiment more with damping and LFB values.
Will test all your files further when I´m back from vacation

 

I find the self centering is far too fast for me on my simplicity SW20 , Danielkarts last but one file has worked best for me as there seems to be more dampening built in by default .

 

I also said today that the damping and lfb amplifies the oscillation. Anything above 0 amplifies it. And suddenly people come and say the same problem with the oscillations. I still say that it has gotten worse since 5.01. Stakanov I can't find a way to eliminate these extreme oscillations, sorry. I don't have this problem with my custom file, that's a fact. I'm at a loss with your and Karsten's file, I can't get any further
Goodnight

 

@Karsten Hvidberg sorry if I disturb, I know that on these formulas you have already told others that everything is as it should be .... but these two changes would be plausible and above all functional fewer oscillations .... is possible only here delete this in bold and red ... with dt now set in static way and equal to 1/300 i have difficult to understand this multiplication and division in red which is practically a little less than 1 and always equal to 0,900900900900 .... and if i set or use dt =1/333 is always = to 1 ... even if i not mistake

(sa_delta_rack (* (/ 1 (* dt 333)) (- steering_angle_rack old_sa_rack)))
(old_sa_rack steering_angle_rack)
(sa_delta_rack (hard_clip sa_delta_rack delta_sa_max))

(sa_delta_l (* (/ 1 (* dt 333)) (- steering_angle_l old_sa_l)))
(sa_delta_r (* (/ 1 (* dt 333)) (- steering_angle_r old_sa_r)))
(old_sa_l steering_angle_l)
(old_sa_r steering_angle_r)

What is the need for this calculation if now dt is static and not variable???
Sorry in advance do not hate me

EDIT: Try deleted the red code ... or in alternative try neutralized the code (=1) for dimostration or for test with game .... many oscillation go away.

enable this on top
(dt (/ 1 300))
(dt2 (/ 1 333))

and now modify the code like this for result = 1 (and not 0.900900900) !!!

(sa_delta_rack (* (/ 1 (* dt2 333)) (- steering_angle_rack old_sa_rack)))
(old_sa_rack steering_angle_rack)
(sa_delta_rack (hard_clip sa_delta_rack delta_sa_max))

(sa_delta_l (* (/ 1 (* dt2 333)) (- steering_angle_l old_sa_l)))
(sa_delta_r (* (/ 1 (* dt2 333)) (- steering_angle_r old_sa_r)))
(old_sa_l steering_angle_l)
(old_sa_r steering_angle_r)

If i right for now or even if the dt is static the code in red can be removed or neutralized as in this example

 

Center_full_ gemischte neue Werte. Relax_us Start wurde reduziert. Kerbs_surface etwas reduziert. Large_Track und Large_offroad reduziert. Federung etwas reduziert. Eine sehr homogene sanfte Handhabung. Sehr empfehlenswert für DD-Basen

Nachtrag: Die Datei kann auch für schwächere Laufräder getestet werden. Reduzieren Sie einfach den Wert dafür
(power_steering_angle 0,15) oder 0,1

 

I am completely Kukus opinion. Priority is to eliminate these oscillations
