Automobilista 2 Custom Force Feedback - Overview & Recommendations

Thank you @Karsten Hvidberg , the 3.5 file is amazing on my T300

 

do you add any tightening to your wheel/file.
While it’s good as standard I find in more accurate to have some 3/4 tightening.
You could try values of
0.08
0.02

and then run lower Lfb

 

Hey Stakanov,

I hope you're ok & wish you well soon!

Reg. relax_over_steer and so on, those are now done differently and the values are for example:

(relax_os_line2_start_y 0.0024) #relax_os used for over-steer: relax_os
(relax_os_pos 0.00144)
(relax_os_width 0.0105)
(relax_os_coef -0.015)

(Note the desmos graph link in there, it is hugely helpful to go to that url to see it visually.)
So there's much more precise control of the over-steer curve & it's relaxation. Same for over-steer and yaw.

The file is still experimental, yes. A few more things to fix, although my time is limited these days...

Best,

-K

 

Is this file in question compatible with sc2 pro's ?
I feel like my car is driving on ice sometimes and I fail to feel the response from the car before I lose it. Been reading the last few pages and this community seems pretty pleased with this file.
Have a great day

 

Hi Kuku, I will try, please can you tell me which variables I need to change for tightening?

The file in your signature is great too. I just tried the latest 3.5 file without any modification in a GT3 race at Brands Hatch and I was able to feel the car in a way I never felt it, I even was able to purposely drift the 720S so naturally I was impressed.

Don't have access to my PC right now but as I remember, I had 70 Gain, 50 LFB/FX/Damper in game with your file, just replaced the custom ffb file without any modification in the values nor ingame.

 

It’s basically the first two lines of scale variables in the file.
my ( now out of date i guess) file already had the tightening in place at top of file. so you could copy and paste these lines .

i haven’t finished tuning 3.5 yet but will be very similar.

 

The file was developed on an SC2 pro base and I think if it feels like ice you have not found the right settings yet.
Its different in-game settings than Default, so you will need to tinker.

But first it's important you don't use strong filters in TD. In TD I have all filters off, except reconstruction filter, that I have at 1. More than 1 will go more and more ice for sure as it just smooths it out.

You will not regret putting in the time to get this right on that wheel base.

 

You could test the latest experimental rFuktor 3.5 file with these in-game FFB settings from AMS2 control options:

Gain: 32-38 (I'm using 37)
LFB: 9-12 (I'm using 11)
FX: 25-32 (I'm using 25)
Damping: 10-20 (I'm using 20)

I'm using SC2 Sport wheelbase myself but as far as I know, the optimal settings for SC2 Pro and SC2 Sport should be very close to each other. Try those in-game settings I suggested above and experiment with those, you will eventually find the right combination that feels right for your wheelbase.

 

Thanks @Karsten Hvidberg for the hope of healing

The graphs for the functions are very useful , but only for confirmation, so for example, if I wanted to insert a personalized "relax_os" in the karts I have to insert all 4 lines you mentioned in the usual way, as indicated below ???

(relax_os_line2_start_y (if isKart 0.0024 relax_os_line2_start_y))
(relax_os_pos (if isKart 0.00144 relax_os_pos))
(relax_os_width (if isKart 0.0105 relax_os_width))
(relax_os_coef (if isKart -0.015 relax_os_coef))
(Obviously with different values....)

And therefore the same for the relative 4 lines inherent to "slip_crossover", "relax_us" and "relax_yaw"???

 

I’m pretty lost with those values myself. so haven’t changed them . they seem low so so probably will only delay feedback if they are raised?

 

Yes, correct.
If you want to adjust them, do so in the graph first, so you see it. Then take those values and insert in the file.
It's the first 4 lines of values in the desmos graph in the left side & same order. Just desmos does not allow full names(or maybe I just didn't look up how to do that), so it's 1 letter names instead.

 

(relax_os_line2_start_y (if isKart 0.0024 relax_os_line2_start_y))
This should represent when the curve of the relax function begins with respect to the starting point ie at zero forces (zero over_steer)
Start

(relax_os_pos (if isKart 0.00144 relax_os_pos))
This should represent where the relax is found along the curve, the higher it is the more relax occurs away from the zero force
When relax over_steer

(relax_os_width (if isKart 0.0105 relax_os_width))
This should represent how large is the relax is in the above position, the higher it is the longer the relax itself
How much width relax over_steer

(relax_os_coef (if isKart -0.015 relax_os_coef))
This should be the coefficient that is the amount of relax
Quantity of relax over_steer

Depending on the value if you exaggerate it can amplify the relax itself and / or turn it upside down in amplification depending on the combinations you have to be careful about the quantity of positive and / or negative values because you could overturn what you are looking for and amplify rather than relax ...

I hope I didn't say stupid ... only @Karsten Hvidberg can confirm we wait

 

I can add a little explanation:

There are 2 lines:
1) The relax line, that's based on x^(x^relax_coef)
2) relax_os_line2_start_y is the starting point on y of line 2 going from that point (0,starty) to (1,1).

Then there are 2 other values: relax_pos & relax_width
They control the position and width of an interpolation function that creates a smooth transition over the given width.

The final line is using that interpolation function to combine line 1 & line 2.

I hope this helps a little.

 

Thank you very much to Karsten and Tumi for your feedback.
i have downloaded and installed the 3.5 experimental version i found a few posts back. hopefully this gives me the feedback im looking for. (I will test tonight)
i believe i was using an older file from a few months back but admittedly i struggled with my TD settings and in game settings.
this is the 1st time i get a sense of direction on where i should at least start my baseline and adjust from there.

 

If it helps, here's my True Drive settings (got them directly from Karsten himself over a month ago):

Ok so I tried tumi's settings I copied everything except the reconstruction filter which I left at 1 as per karstens post from earlier and I can say it's a world of a difference I am definitely getting more response and control from the car.... despite the fact that I need like 5 years worth of practice lol I'm able to push the car and control it much better....you guys are amazing...now I just need to find the same equally effective settings for my other titles

 

Yes this is the problem, nothing else feels good anymore, I’ve even tried blending recent code into older Pc2 silver files , but it doesn’t seem compatible.
Not sure @Karsten Hvidberg has time to update that side these days and it’s fast becoming obsolete as a title.

 

Shame but understandable ams2 is a newer tile with more promising updates likely on the horizon... That being said I like pc2 and just like having a wide variety of sim games to use with my rig... The more options the better but that's just my opinion... For right now I can say I'm loving and 2 so the more refined it gets the better

 

Hi @Karsten Hvidberg et al

Really loving Rfuktor3.4, but I do have to chime in with a bug report which I've seen reported a few pages ago: when the weather transitions from dry to a fully wet track, the FFB gets increasingly violent. It starts as though the road noise and bumps are massively amplified, and ends up with the wheel wrenching violently in the direction I turn it. Switching to default stops it, switching back to Rfuktor and it's violent again.

This has happened with several cars on various tracks, on test day and quick races, but it only happens when a session starts dry, and transitions to fully wet. Races that start and stay wet or start wet and transition to dry do not exhibit the behaviour.

Hope this helps, please let me know if I can provide any other info

 

Yes, the last experimental 3.5 posted here fixes it to a large degree.
The problem is that some of the madness tyre variables start acting weird for some reason.
I will have to add a custom calcvulation for tyre deformation to fix it to a level I would be hapopy about for the final 3.5 file.
