Automobilista 2 Custom Force Feedback - Overview & Recommendations

@Danielkart and @ALL I'm not on my computer today and I will stay away from home so I can only search the archives on my mobile, in these spoilers there are the first version of tear implemented by Karsten ... you or someone could try if it works or if it covers also the feeling of rubber ..... perhaps some of these give important indications.

First tear...

A subsequent change to the tear took place in rfactor 4.1 with the insertion of the deadzone...

And then in 4.3 it changed again in the first embryonic forms of the present one,,,,

That's all, after these the latest version of tear took over (obviously I haven't published all the minor changes that have occurred in the individual values)

 

Is there a problem?

 

I’m almost caught up

the way than Daniel has implemented the scrub and tear isnt dissimilar to the way I’ve been using for some time, except for the zero tear scale. So it mostly feels very similar but does come through the wheel smoother,

for me, tear has always been a snag feeling which is why I’ve always pushed it out to be at edge of grip threshold as a que that the tire is almost ready to give in.

it also gives a good initial lock up feeling .

some tires have more tack than other, and on some tracks with the tacky tires the tear can be quite rough feeling.

making the scale low does smooth this out for sure. But there is a trade off that the tire sensation is quite same same throughout if you know what I mean.

so I’m not saying I don’t like it at zero, I’m just saying there’s still a case for it to be used depending on taste.
I’m not sure there’s any actual bug with it, it’s just an effect.

 

sorry karsten , English is not my mother tongue. I mean Tear_scale is responsible for the wrong scrub feeling and tear feeling. How long it's been you'd have to look up what Stakanov said. I usually never look back at what used to be. I test and go by my feelings and adjust values accordingly. But I'm sure it's been like this for a long time.
regards Karsten

 

Ive been away for a week and this thread has blown up. I now have some testing to do. Thank you all

 

hey kuku
I have a different opinion than you. Tear_scale interferes with every value above 0 . But if you have a different feeling then use it

 

I don’t mind it at 0 at all, it feels fine.
But trying to understand what you mean by a bug ?
What values is it interfering with specifically.
I’m sure Karsten would be able to correct it and it may improve everything if there is something unintentional happening.

 

It's weird how we all feel tear and scrub are better or worse, perhaps it's a thing that is more wheel base dependent than most other things... Great if these efforts can result in somethi g that works well for most...

 

Yes this is always a strange anomaly, but I ( you may remember back in the day ) have always felt low scrub frequency a different way even with my old T300, compared to what you found best on your trusty simucube.
but for me it has carried over to my DD. The preference is still the same.

 

I do think I would now prefer lower frequency tear, and low force on it.
It was made for coming slightly before scrub, but it also makes sense to ha e something change on lateish scrub, for variety as you also pointed to earlier.

 

its always had a small tug on the wheel effect to me. So if it comes in early in loading it’s trying to repeatedly tug on and off as it skips over road texture.
This interferes with the progressive loading feels, so that’s why I liked to push it out until later or closer to the grip limit.

anyway, I’ve slowly morphed my 5.0.1 tune bit by bit through to exp 6 and it’s feeling quite good, but now I’m going to go back and mix and match a little as there’s a couple of things I liked more previously. But exactly which bits is the fun part. Plus I’ve got to see how some of the others variations feel.
Tomorrow’s job

 

No @Karsten Hvidberg there are no problems, the only anomaly is that with tear_scale_effect at 0 the tires feel different even when there are still neither of the two scrub tear effects (in the straight and at the beginning of the curve), no matter how much you delay the effects arise ... the question is "it's normal that the tires feel different when the tear_scale is different from zero" ??
or
Why does the tear change the normal tire if the effect has not yet arrived and when the tear is the last effect why does the scrub also feel different if the tear has yet to arrive to the last?

So with the zero tear the tires feel good without effects (only the rubber work), and I continue to feel it well even when the scrub arises which adds to the sensation of normal rubber and obviously the tear does not arrive and I do not feel it and everything it is OK ... and we come to the loss of grip.

If, on the other hand, I enable the tear and I impose it that it must arise even very far before the loss of grip .. it happens that the tire start feels different without the effects having arisen yet so I don't feel the work it was doing as before, even the scrub feels different as before and at the last the tear arrives ... but why change the first and second step I do not understand...

So we are not talking about how the effects should be, as you like it or as modify it, but only because an effect modifies everything else when the effect has not yet arisen

I hope I have interpreted @Danielkart 's thought well....

 

I've done some testing by disabling Scrub and focusing on Tear effects alone. I also disabled rear-tear to have a clear indication of when front-Tear begins and how it progresses. I also increased Tear Scale to make it more obvious however, I now can feel a cyclical variation pattern within the Tear effect. In other words, the intensity (maybe frequency) varies in cycles throughout the cornering phase, so the effect is not at all consistent.

Perhaps those changes I made cause the cycling result? At any rate, pushing the Tear Threshold to about 0.2 feels better through the cornering phase as lateral pressure is near its high point.

Update: In the Beta thread, others are also mentioning "Pulsating ffb effects" with certain cars (One being the Stockcar 2022). There may already be a fix in place for future builds so, best to wait and see if that solves the issue I mention above (Tear effect).

 

I have a big guess, will test and let you know

 

thanks for your tip, the problem with stock cars might be better soon

 

yes, it is as I suspected. Enjoy drifting and control with the stock cars. The stock cars before were very, very, very bad. Now they are joking
Unfortunately, there is bad news as well. Because I know that someone will be very sad here

First the not so important, just a matter of taste:

Stakanov your middle is a bit loose I think it's better with 30

over_steer_scale and under steer_scale can now even be increased 1.5/1.5 but better both values the same as Stakanov has. The same values give a very homogeneous and less nervous steering wheel (with dd1)

Test: With Toyota Corolla Stock car 21

Route: Spa

Rack Settings:
Switch off all yaw values with #, I think there are 7 values
These values have a massive impact on the ffb, unfortunately that's the way it is. I've been dating yaw for a long time.
Compare it yourself how nice you can drift

 

Guys, let everything rest for a while. I notice that the thread is very restless. It was a crazy week with a lot of new things. Just enjoy this ingenious simulation
regards

 

yes , while it’s been awesome to have so many new thoughts and furious testing from multiple users at the same time ( which isn’t all that common)
It’s getting hard to keep up , which makes it hard to come to conclusions.
But there’s definitely progress which is a good thing .

 

The edge of grip feeling in this file is really really good. That feeling you get when all you want to do is push the car a little more.. then a little more... and more. It's really fun.
