Automobilista 2 Custom Force Feedback - Overview & Recommendations

I don't know what to tell you ... I'm happy for you but here on the parabolic curve we have repeated gunshots and not a high level of detail (the whole station dances to me and I don't have a DD) ... otherwise everything is perfect including Doms correction ... and of course I can lower gain and fx (Peter does this) but the jolts are only attenuated and I lose in all other aspects and situations ... in this condition I prefer to stay where I am with my settings and change on default only when I'm on Monza ...

 

While not technically understanding what to recommend, I take the liberty of giving my contribution by having a Logitech myself.
I tried to load the DomFix file, that of Kuku, that of Stakanov, that of Peter and finally the original of Karsten, all in version 4.6. I used 2 machines, the Gen2 and the Ultimate, and in the game I used Stakanov's values ie 95-30-30-55 in the track Monza 10K!

ON THE PARABOLIC CURVE THE CAR IS UNDRIVABLE, THE SHOCKS ARE DRY AND REPEATED AND SOMETIMES THE CAR SLIDES TO THE RIGHT, lowering the values the situation does not become manageable but only more attenuated.

I hope it helps to understand, but Stakanov does not exaggerate here on Logitech we really dance and then maybe on DirectDrive it feels less!

 

Try Stakanov's file (all in one v2 or v3), but also last file version of PeterStafani and Kuku are good.

 

I had the same problem on T300 , it clipped and used every bit of the peak force available on these bumps.
The bumps are real and what you are feeling is the car bottoming out . if you bottom out at speed the car will move off line.
the problem is you are feeling it too strongly.
I suspect that is because gain ( peak forces) are so high. but i understand that you need it high because it adds more weight and resistance etc.
So the thing that you logitech guys need to find is how to alter the file to give more headroom. ie lower gain but still nice low load feel and weight.
I would see to start with zero static force removal . and see if that helps you be able to lower overall gain.

 

The logitech Gaming controllerSoftware does not alow to alter the different static, dynamic spring and damping forces like the TM driver does.

 

t

the thrustmaster software is just as basic.
i’m talking about in file .

 

Sorry for delay @Kuku Maddog but before answering you i wanted to test all your previous Delta, V1, V2, V3, High files in addition to the last one published, but I can't find one that minimizes the jumps/jolt during the Monza parabolic, I tried to lower and higher the entries in the file related to the static force but nothing works!
Where are these your files and/or your instructions and/or value from which this effort on T300 to solve the Jolt problem is highlighted?

Why if you believe that there is a defect, do you continually belittle it? Of course the bumps are real but it's the FFB Custom that doesn't represent them in a real way on parabolic.and comparing myself with others, it is not only the logitech base that suffers, I begin to not understand you.

Is the gain high? But have you seen Stakanov's telemetry? The forces are all low even with high gain and only the jolt makes the red bar jump up intermittently! It's a defect not an a wrong setting and not a simple abnormal micro/largebump to smooth and we guys at Logitech do not understand the reluctance to believe that there is a defect, it comes to say that it is normal that the car slams under the bottom, that the default FFB of Reiza does not do the defect because it does not work or because it is not said that the default is correct, they seem to me to be stances that are difficult to sustain, it would no longer be useful to find a solution so that the defect is resolved, if the problem for you is not noticed or not relevant, it is not discussed.
Sorry Kuku I don't mean to be rude you are a pillar in this forum but i expect solutions (values, codes and files) , plus I also apologize to @Stakanov (since I mention it) that which in my opinion should make him a saint for patience, but we need a solutions NOT A PLACEBO and now for this only Stakanov (with its research on the code and its limitations), @Domagoj Lovric (who now published his right-left fix) and @Karsten Hvidberg (when him was on the forum) are the only that i can see struggling to technically try to solve the defect, the rest seems to me chatter and philosophy.

For one parabolic curve you cannot twist a file or setting and make a steering wheel work very badly, this is not a solution, I agree with Stakanov that if a solution is not found, the custom file must be used for everything and no for Monza and swiching to the default,

EDIT: Not to be nice to you but, now that I've tried your files well, I forgot to compliment you on your files which I found very pleasant almost like those optimized for Logitech, good job!

 

I’m glad to hear your new wheelbase arrived, and I’m looking forward to trying your next file!

 

we aren’t actually in disagreement , when this track specific issue arose the the first time, we did identify that aside from the side to side jolt, ( which is what we referred to as the jolt, not the harsh bumps in general)
It was noticed that the banked section of track had a hyperactive state that made bump forces go through the ceiling.
This hasn’t changed, but it seems the lower powered wheels struggle with it more than higher.
I never made a file specifically to reduce this effect, because like you say it’s not worth it for a small section of the total track menu.
And also myself and others spent a considerable amount of time trying to find a workaround for the Jolt, but ultimately failed to do so.
It required expertise and I have to laugh when Dom “briefly” looks at it and fixes it just like that.

Again I’ve have stated multiple times there is something funky with the track mesh in this section, and the custom file is able to pick this up, when the default doesn’t.
But with a little more smoothing to bump affects or general load it can be made a little more comfortable, but doesn’t flatten the bumps at all.
maybe one day Karsten may be able to include something to limit max bumps or something ?

Because on this section of track there seems to be nothing to constrain peak bump force, especially if Gain values are high.

 

Right...
Even though there's a significant update due tomorrow that could change the FFB landscape.
I look forward to seeing what comes with unexpected new FFB.

Ive settled on a current state set up and tune to suit my new Simagic Alpha mini.
Its been a new learning period trying to dial in the base more than the file.
I found the finer details like texture etc needed a little boost in file to work better with the current Alpha manager software. Also I found that it quite liked the scrub out of older Easter Fuktor, so have presented both options.

Outside of that , what worked and what didn't on the t300 crosses over without issues
but ive tried to keep things very similar to stock 4.6 but also a little less complicated , so it should suit a wide variety of wheel bases and can easily be tuned by anyone.

Once again a massive thanks to @Domagoj Lovric for helping with Monza issue, I have included the base rFuktor 4.6 by our inspiration @Karsten Hvidberg with jolt fix for future reference also.

Edit : updated Delta S can be found here.

Found another element that is part of the jumps on the parabolic ... I think only one or two problem is missing.....

These 5 lines bring together and summarize the whole custom file, if you delete the single items backwards (one by one) in the first 3 lines (starting from the last characteristics in color) ... you will notice that only by disabling the "rear" in the road festures (delete this word in the second line of code) will partially reduce the jump in the parabolics ... this means that in the end the remaining problem is inside the rack_momentum or its subsections ... part of the problem has been removed from Dom (the right left slide) the remaining part is still present and can be in there only because the rest is all disabled (no in the road futures and no in the effects) ... facts and not personal interpretations.

(rack_big rack_momentum)
(road_features (+ slope_large suspension rear road_bumps road_details (* texture texture_scale 0.5)))
(effects (+ engine_effect tear_effect scrub_effect flatspots_effect))
(all (+ rack_big road_features effects))
(output all)

Would it be possible to know who has the qualification of beta tester and especially who among them writes publicly here in this forum?

 

.double

 

this Rear element is just the application to the rack of the rear bumps .
Lowering rear bumps scale and playing around with
Rear bump Hard which alters the spring force would advised instead.

(rear_bump_scale 0.6)
(rear_bump_hard 0.9)

Or maybe apply some more smoothing to its workings.
(rear (- rear (smooth rear 0.02)))
(rear (spring rear (* rear_bump_hard 10000) 1.0))
(rear (* rear 0.0036 rear_bump_scale))

 

Right is just the application to the rack ... the rest of problem is in the rack if you smooth or reduce is a placebo

 

Well I start to buy too, so the effects amplify the problem but they are not the origin of the defect, but in the rack the main cause persists.

 

Yes, correct, if you use the Easter file the defect is much less noticeable and in fact it is not a coincidence that the secondary code for the "rear" effect is missing in that file and also the secondary code for the "scrub" is different, but it is not a solution is only causality as the underlying problem was already present in the Easter ... resetting or using those codes is placebo ... I will do it too if a solution is not found but it is cunning.

 

The reason it’s not sensitive in Easter file, is because it doesn’t have the caster trail geometry forces, and is taking the force from the tyre effects instead of more direct steering angle.

 

For me caster trail is problem maybe only for the slip not for the jolt in the center of wheels in any bank of parabolic … even now i have slip even if reduced if you test with high gain and high velocity … if you enter in Easter the rear and other effect whitout trail the jolt is here … try first a reverse test!!!

EDIT: Or in the opposite delete trail line code in this file … the defect is here….

 

yes the caster trail and direct from steering rack force application is the problem, but it is also the strength of this custom file, and works perfectly well for 99% of the tracks in the title.
So you see, it’s got a lot to do with the classic parabolic section of track . It’s different to any other surface.
Before the left to right fix from dom, it displayed a most peculiar characteristic in the second curve, it would pull the left wheel upwards towards the barrier and the right down towards the grass. Even at walking pace.
That is not something you would expect.

 

Repeat i edit after: Iin the opposite case delete trail line code in this file … the defect is here….
