Automobilista 2 Custom Force Feedback - Overview & Recommendations

Yes, I am already in the process of editing together with dear tester friends ... today I have little time but by tomorrow evening I should complete the update and tuning of the previous 4W file in version 5.0.1.4 final (I want to try it and adjust it with as many machines as possible and with as many steering wheels as possible other than Logitech) ... and I think that making the changes to the file (which are shared by several different steering wheels) focusing more on the main code than on the tuning of the variables, is bearing fruit.

@Karsten Hvidberg in addition to the "grip in front and rear wheels" I found another change in the code values that allows you to adjust the effect as you want so that everyone likes it by adjusting its intensity (I will explain it later) ... I'm in turmoil and I really like it ... I hope it's not just a sensation of my head!!!

 

I was scrolling thru the file and saw the following (don't know if this is intentional or a typo or leftover)
1. (sa_delta_rack (* (/ 1 (* dt 333)) (- steering_angle_rack old_sa_rack)))
shouldn't this be 300
2.
(grip_feel_rear (min 1 (/ (+ (* grip_rl rel_weight_FL) (* grip_rr rel_weight_FR)) (max 0.0001 (+ rel_weight_FL rel_weight_FR)))))
see values in red. if it is for rear should it be
(grip_feel_rear (min 1 (/ (+ (* grip_rl rel_weight_RL) (* grip_rr rel_weight_RR)) (max 0.0001 (+ rel_weight_RL rel_weight_RR)))))

 

Whoops

 

Sorry trigger fingers

 

Hey Lars,

Thanks for posting,
I can see why you ask for both #1 and #2, but everything is as was intended and no problems.

However might change it slightly at some point, so thanks for pointing them out.

 

I'm undecided about the center ..... I need to think aloud, and even though I think I know the answer, I think I need comfort and affection from @Karsten Hvidberg ... I specify that I don't want to deceive you and you are not my type!!!

Let's get to the point and assume the example of the file......
center_full_low_velocity 0.8
center_full 0.4
(center_full (blend (min 1 (/ kmh 80)) center_full_low_velocity center_full))
----------------------------------------------------
# 1 - If I go at 50 kmh we have:

(center_full (blend (min 1 (/ 50 80)) 0.8 0.4))

50/80=0.625 which is lower than 1 so "(min 1 (/ 50 80))" is equal to 0.625 and the center becomes.....

(center_full (blend 0.625 0.8 0.4))

So from 0 kmh to 80 kmh the range of the voice "(min 1 (/ x 80))" always goes from 0 to 1
----------------------------------------------------
# 2 - If I go at speeds above 80 for example at 150 kmh (but it is the same for any higher speed after 80) we have:

(center_full (blend (min 1 (/ 150 80)) 0.8 0.4))

150/80=1.875 which is higher than 1 so "(min 1 (/ 150 80))" is always 1.00 and the formula becomes.....

(center_full (blend 1.00 0.8 0.4))

So, beyond 80 km / h, it always remains like this at whatever speed
-----------------------------------------------------
So, which is not obvious at first sight, I would still obtain a differentiation between the center at a speed lower than 80 and the center at a speed higher than 80 even by setting the same value of both center_full and center_full_low_velocity

(center_full (blend (min 1 (/ kmh 80)) 0.8 0.8))

Because....
at 50 for example it would be (center_full (blend 0.625 0.8 0.8))
over 80 would always be (center_full (blend 1.00 0.8 0.8))
------------------------------------------------------
I got it right, no?

 

Almost.

Blend works like this:

(blend b v1 v2) = (1-b)*v1 + b*v2

So "v1" specifies what blend result should be at velocity 0 and "v2" specifies blend result at velocity >= 80. Everything in between velocity 0 and 80 is the pct as provided in "b" between "v1" and "v2".

In your example, since both v1 and v2 are 0.8, the result will be always 0.8.

 

Ok @Karsten Hvidberg ... thank you very much for the explanations ... I was right to think aloud then, I would have made a mistake just following the code ... the mathematical functioning of the "blend" is now very clear ...

 

Such a busy topic...it looks like you are non stop working to improve AMS2 FFB.
What are you or others recommending for a CSWv2 now? Ive got the latest from post 2, is that the file to use and if so what in game settings to start at? Does dampening work as dampening again?

 

Hey @2ndLastJedi,

The last file is 1 page back here in this thread. I would think you would need to use slightly higher gain than my suggestion for Torstein.
Damping is now damping again, yes.

 

Hey @Karsten Hvidberg
Can it be that more gain is needed after experimental 8 vs your latest file? Or are you still using the same settings for your simucube?

 

I increased master_rack slightly in the last file:

(master_rack 0.76)

So the earlier experimentals required slightly more gain in-game compared, yes.

 

I’ve found the last couple of experimental files rather odd feeling, like it’s lost lots of weight and strength of detail, I’m not sure what’s happening or if I’m getting a bug or something, but it’s just strange , feels very vague , soft and mushy.
I’ve not got time to investigate why this is happening, and are working on something else in between, and trying to test different features individually.

 

Your latest is a massive improvement from the older rfukter files i tried. From my little time today I think it gives the dampening to the Formula v12 that I've been missing.
More testing to come.

 

@Karsten Hvidberg
Have you tested your latest file with Karts.
for me they seem undrivable

 

Für alle, die eine ehrliche und hervorragend funktionierende benutzerdefinierte Datei suchen

 

@Lars Mars , I think, if I'm not mistaken, it hasn't been optimized for a long time ... regardless of karts I've always had better driving experience or better consistency using FFB default or default +, try using it. .. so I would recommend to recalibrate the customized file by comparing it side by side and step by step with the default ffb and find at least (voice by voice) the values that bring the two sensations closer, even better if you improve ... being just a very unpleasant tuning, it would be convenient for someone to take care of it to relieve Karsten of this task ...
If Karsten can't and nobody has the time or the skills to do it, after I finish my ffb file (maybe after tonight), I'll try to recalibrate the karts one of these days ... I hope to have the skills and especially the strength because now I'm a little tired due to my low stamina ...

 

As @Stakanov also mentions, in short, no. Time has not allowed it, unf.

 

I have to agree this file feels very good on my DD1.

Thank you for posting it.

 

OK guys, the kart tuning remain WIP or not touch, but the file is for me complete, functional and tuned ... i attached here the last mod with name rFuctor 5.0.1.4 - 4W. GRIP & STRECH.MOD (based on 5.0.1.4) and i also attached my previous rFuctor 5.0.X.X 4W.GRIP.MOD (based on 5.0.1.3) with also the last original Karsten's file rFuctor 5.1.0.4 modified only in code alignment for graphic comparison with the program Notepad++ and plug-in Compare.

Like last time the file is unique for everyone (DD, High or Low End, Gear or Belt) and I have not made any specific optimization for the Logitech bases, indeed the total tuning of the file was made by your values that you mainly use DD bases and good even for me.

For your convenience, I added more explanatory notes and various advice (for novices) in the file, moreover, to cover the whole range of steering wheels, I added the alternative setting values if the same choices between users and/or the different steering wheels is not possible, especially with DD, because are irreconcilable.

###########################################################
Name: rFuktor 5.0.1.4 - 4W. GRIP & STRECH MOD
Mod and Tuned by Stakanov for all wheels
###########################################################
# ADVISES FOR LOGITECH G923/G920/G29
1) In game setting, select "Custom" with this starting value:
GAIN 95* - LFB 25 - FX 65 (+/- 10 to taste) - DP (Damping) 15.
*Then, in the car setting, use +/- % of Gain for car to taste!!!
2) Logitech HUB Setting
Last version with default value
(900° and all sensitivity to 50)
3) AMS2 Game Menù Setting
900° - All deadzone to 0 - All sensitivity to 50 except the throttle on range 20-30
If you use manual clutch try to set also this slide of sensitivity on range 20-30

# ADVISES FOR OTHER LOW/MED GEAR/BELT WHEELS (Logitech or No)
1) In game try to start with your usual value or with this starting range-value:
GAIN 50-95* - LFB 05-25 - FX 30-70 - DP (Damping) 05-15.
*Then, in the car setting, use +/- % of Gain for car to taste!!!

# ADVISES FOR DD & HIGHEND WHEELS
1) In game try to start with your usual value or with this starting range-value:
GAIN 30-80* - LFB 00-20 - FX 30-70 - DP (Damping) 00-15.
*Then, in the car setting, use +/- % of Gain for car to taste!!!
###########################################################

EDIT: If you fell heavy the wheel in the cornering try to go down with gain, but if you don't like, the value are only to be adjusted using the alternative values in the file and according to your tastes and wheel ... the items for change this in cornering are: power_steering, power_steering_angular, velocity_res_scale, velocity_rot_scale, velocity_rot_limit_coef .... but even for the general load force feel we have this others items: tyre_resistence, limit_high_df, exaggerate_load_feel, static_force_reduction and the two variables exp_static_force_reduction ... ;-)

I hope you like .... thanks to all those users/friends who have had the patience to help me, since I can't do long sessions of tests.... good night to all!!!
