Automobilista 2 Custom Force Feedback - Overview & Recommendations

Just did some more testing with different cars.
Im not sure how realistic sound fx is for tyre scrub, but the higher values Im using feel much better in line with my audio cues now. In turn making it much more believable and immersive.

I found it really noticable in the 911 RSR GT3 and have the frequency pretty dialed, except for the fact that the feedback through the wheel is present before the audio cue kicks in.
Its now a bit unclear when the tyres are losing their grip and the understeer starts.
It would be really cool if this can be solved by raising or lowering thresholds for the FFB/tyre FX...

 

Nice!

I can add in some sompler threshold control than is there now.
Currently there's only really one:
(scrub_deadzone 0.0)

You can raise that to have scrub appear later.

That one is interesting

I used to think just as you but then had discussions with @Shadak about it, since his opinion was the opposite.
Turns out it's down to suspension type which way it pulls

Ok, I hope tyre scrub effects are more in sync with tyre FX than with the actual physics then.
Or more likely the values are so exaggerated now that scrubbing is noticable earlier than it should be.

Anyhow, I just left town for a few days so unfortunately I wont be able to try this out untill Im back. But I will try it out and let you know how it went!

Cheers and tusen takk!

 

Depends on what you want to "show" via ffb, either suspenion moving up so the side you hit moves up in the wheel, right curb, right side (tyre elevating in relation to the opposite side). Or you can simulate relation between rack and axle. Cant remember which it is in default ffb tbh.

 

Might depend on the tyres used, when I drove the Porsche cup car it was very noticeable when the tyres came close to the limit how I could feel the rubber "skipping" on the surface in my hands, same with an M3 race spec, then I drove rally lancer Evo and there I didnt feel the tyres as much. Not sure if Karsten changed anything in the last file, I dont think he has but we had the tearing/flexing of the tyre frequency lower and scrub much higher, imo raising the scrub even more would make it too noisy and seem more like a vibration of the wheel. Also should raise more with speed etc.

Thats one of the things we tried to simulate with tearing/scrub, not really the screeching of tyres as thats already in the game as a sound effect. When I drove a formula, there wasnt a lot of feedback but it was a damp track so maybe it was that.

 

Different wheel bases will accentuate things more than others, with my old T300 it used to have pronounced higher frequency effects, and it was great with the normal scrub.
But currently ( software could be better) my Simagic doesn’t highlight the high frequency as well, but is better in all other aspects.
The normal 4.6 scrub feels a bit grabbing on the wheel without the subtle vibes , hence I’m using older scrub which is allowing a bit more slip and good load up of subtle vibe for information cues.

 

Liking your latest file @Kuku Maddog , made a couple of tweaks to improve slow speed forces and now I reckon this is a keeper.

 

Hey Alegunner!

Nice to see you're still around too

 

Hi Karsten, good to see you back as well

 

The last time someone made a return like this , they wrote a book about that millions still read today. Think it’s called the Bable or something like that
gifs and stuff: Image

 

lol, Karsten is actually the author of Bable: Old Testiclement

 

Hahahaha,
I don't think it can be kept a secret any longer who actually came up with the "rFuktor" name, that was several days of giggles! Thanks @Shadak, it still can make my day 8)

@Kuku Maddog 's "Bable" is pretty sweet too 8)

 

for me and my TSPC racer, default+ is really good, good enough to be on par with the Custom Silver Raw - rFuktor 4.6 - Momentum Rack 6.3 - Karsten with Shadak & Panos - High end file I was using prior to 1.3 Game update

talking about update, one thing I noticed, actually 2, is that kurbs feels is weaker and I am getting low to zero effect driving off the grass (I know I shouldn't but ....)

PS1 Karsten, nice to see you back here!
PS2 @Reiza When will we be getting key bidding for LFB, damping and stuff, like PC2 offers and is super useful with Custom file FFB, not only Gain?

 

I think you have a very good point about the frequency raising with the speed. I think it should also go up or down relative to tyre compound, track conditions, weight of the car, sidewall tension etc etc. Things that are probably beyond the Madness engine, or any engine in simracing for that matter.
Im not sure about this though, maybe one of the devs can weigh in on this, but the tyre FX seems to be a single non dynamic sample of a tyre screeching/scrubbing.

Whatever the case may be, with the values as per the original FFB files the frequency of the FFB FX felt very much out of line with the sound FX, totally breaking the immersion for me.

I still need to figure out how to delay the FFB FX by setting the deadzone Karsten mentioned, but if I can make that work I think I will keep using it.
It does indeed make it more noisy like you said, but for me personally it feels a lot more immersive if its in sync with the audio.
But ofcourse this is also totally subjective and a matter of personal preference..

 

Oh yes, FFB will be about compromise a lot, its not easy to represent real life driving in all aspects. If we could get all the information about tyres and road surface etc. we could dial in the ultimate feel but tbh that would require people who have RL experience with those kinds of tyres and surfaces or at least relevant data.... that would turn this into a 2nd job which none of us can afford. I think its already possible to do so much with Karstens ability to put this all into a single FFB file and thats the beauty of it, you can quite easily change the frequencies if you feel like you need to raise them

 

On a real car, when you hit an uneven right wheel, the steering wheel pulls to the right more or less.

 

@Karsten Hvidberg
I haven't heard from Stakanov since yesterday, I know he has a big (health) problem to shoot at, I hope he can come back here in a week or two and win the duel.
In these 2-4 days in chat we dedicated ourselves to the FFB Default+ preset with our cheap Logitech G920 (or rather he advised and I tried to give him a confirmation or not of the result) and came to verify the goodness of the new Reiza Default+ profile respect to the old Defult profile.
In particular and in summary he believes (which I share) that on the low belt/gear band, using tons of damping and effects, medium LFB aids and finally not too high GAIN, it is possible to obtain an FFB suitable for almost all the cars!!!
These are the settings: GAIN 68 LFB 48 FX 98 DP 88
With this configuration on Default+ and on the Logitech we get (finally) the elimination of the excess of elastic effect, some cars no longer become hard boulders to turn and to correct in counter-steering, you have a lot of information from the suspension, the weight of the car and the trail when braking, and finally, only some cars have little acceleration trail and perhaps become too light but always consistent (Stakanov only didn't like the Vee formula and the Karts as they are still immature using the Default+).
In short, it seems a great improvement and all the cars have their own distinct and drivable personality, it seems to change almost steering wheel between one car and another.
Doing the summation, he therefore judges it to be very similar in the background to the rFuctor 4.6, a file that he still prefers over the Default+, as the latter remains less energetic, less informative and detailed about the wheels, with an effect that is still too open and rubbery and finally with a minor trail in acceleration.
Although deficient, however, it highlights the default+, as free from defects or rather from the one or two main imperfections that currently occur in the rFuktor 4.6:
1) the "jolts or anomalies" in the central area of the steering wheel above the parabolic curves and the cements (Monza10k, Daytona, GreenHell, etc.) if the trail_strength_feel, rear and caster code are used;
and/or
2) the "oscillations" in the central area of the steering wheel with Formula cars if the trail_strength_feel, rear and caster code lines are not used.

The rest were summed up very well by the others.

I hope he hasn't written any imperfections, have pity on my level of technical knowledge and allow me a special wish to Staky......................

 

Get well soon @Stakanov

 

Thank you @Manolo,

I am worried to hear that,
best of wishes for safe recovery @Stakanov, crossed fingers for you my friend.
