Automobilista 2 Custom Force Feedback - Overview & Recommendations

@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.

# 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!!!

 

@Karsten Hvidberg ... I have tried in every way to keep the double center but I have not succeeded, the comparison with a single value together with the "blend" remains superior in consistency and coherence ... moreover I have not been able to remove the items relating to weight and to the grip both in the yaw and in the center, taking them off is pleasant on the one hand but makes the sensations more vague on the other ... for the rest I managed to keep all the news related to 5.0.1.4 ... if I can I always try to follow your development.
In this way I was able to overcome my personal feeling compared to the excellent 5.0.1 ...

The conservation of the power_steering is only facade, because if you convert the values you get the same results as your last one file ... why do I do it??? Just to quickly change from damping to power_steering and see how the file reacts ...

Another deepening deserves the topics "grip, strech and slip" and because "scrub and tear" are inverted, but tonight I'm exhausted and I'll make it clear another day!!!

Thanks for all master ... and good night to all!!!

 

Thanks for posting this file . Is this compatible with the current public beta build ?

 

Thanks as usual @Stakanov , you have outdone yourself as always, the file is beautiful and the indications together with the alternative values are useful ... compared to your excellent first modified version (very direct and decisive) I now feel the softer and more sinuous tires, always informative at the same time to a greater balance between the front and rear sensations.
For this reason you added stretch in the name?

 

Thank you for your thoughts and added information, @Stakanov!

And thank you for all your efforts, despite circumstances, a true inspiration, and taking this whole ping pong experience between us all to another level!

I am really looking forward to giving your files a go!

 

I'm currently using it on the public release candidate with no issues.

 

Yes, of couse
Regards

 

It is not a fancy name but it is precisely the use of the strech to influence the grip and other voices ... the game or its physics processes its Strech value for each wheel FL, FR, RL and RR ... in the top of Karsten's file we have how this code is after utilized or managed...

Spoiler: 1° Block

(FL_stretch (power FL_stretch (power (abs FL_stretch) -0.025)))
(FR_stretch (power FR_stretch (power (abs FR_stretch) -0.025)))
(RL_stretch (power RL_stretch (power (abs RL_stretch) -0.05)))
(RR_stretch (power RR_stretch (power (abs RR_stretch) -0.05)))

The strech above indicated in 1° Block (with different front/rear power coefficient) is oblivious linked to the fuction tyre_strech (2° Block where are all the component for the karsten strech tyres) ... where are even the grip function, but even here i remenber that in original code, in the front the grip_fl/fr is absent...

Spoiler: 2° Block

(tyre_fl_stretch (* front_tyre_stretch_feel grip_fl FL_stretch angle_d_l wheel_diam_FL 0.5))
(tyre_fr_stretch (* front_tyre_stretch_feel grip_fr FR_stretch angle_d_r wheel_diam_FR 0.5))
(tyre_rl_stretch (* rear_tyre_stretch_feel grip_rl RL_stretch angle_d_l wheel_diam_RL 0.5))
(tyre_rr_stretch (* rear_tyre_stretch_feel grip_rr RR_stretch angle_d_r wheel_diam_RR 0.5))

I solved the intrusiveness and the management of the grip on both fronts (front and rear) by first leveling the strech equally on the first block of code (increasing or reducing strech), and then I can define how much this modification impacts on the grip and others inserted in all the lines of the second block of code (the items multiply each other and therefore affect each other) ... so now by increasing or reducing the strech I also affect the grip and all the other items within the second block ... this has brought not only the possibility of management but also the homogeneity of the values obtaining less oscillations because there is no difference between the wheels and fronts.

The values to choose in 1° Block are as many as 0.025, 0.050, 0.075 or 0.25, 0.50 and 0.75 ... and so on ... and each one has a different and homogeneous result allowing the values coming from physics to do the rest ... or at least I hope so!

I created and inserted a new variable to manage it "strech_tyres_power_feel"

 

@Stakanov This latest file is extremely heavy for me in cornering. Loads up a lot. I have change a lot of the normal lines to counteract it but is still heavy. If I lower GAIN, it is just too light around the centre. I will try increasing power steering value to see if that helps.

 

Yes @Michael Enright is only to be adjusted using the alternative values according to your tastes and wheel or try using or insert the values of your favorite file

btw the main items for modify this heavy in corner are: power_steering, power_steering_angular, velocity_res_scale velocity_rot_scale, velocity_rot_limit_coef ...

and for general load we have even this items: tyre_resistence, limit_high_df, exaggerate_load_feel, static_force_reduction and the two variables exp_static_force_reduction ...

i insert this note in the post of the file ;-)

 

@Stakanov amazing job, I have a TMX and It's the first time i feel the same feel of rfactor2 in ams2. Very punch and dry feedback, without been too heavy, squishy or rubbery.

I'm using your previous file (rfactor 5.0.x.x), with values 72-85/20/60/15. And all cars at 100% gain (I prefer modify the global gain, it's better or worst than modify the % gain per car?).

I'm going to try your new file and read about which values in the file I have to change to fine tune. Amazing job all of you, dudes.
One question Stakanov, I read that you modify the file using reference from users using DD, but this file is made for low end tier wheels like g29/tmx, no? Conceptually which properties are you changing from the base file and why? Just short and simple explanation, i don´t have knowledge about simracing physics.

 

The DD users feel and express sensations things that the low end does not feel ... if the low end does not feel it I do not see why it should not implement it, so much I do not feel it ... then I add the tuning of the values that we both feel and share ... in the end there are only those few irreconcilable values between a DD and a Low/Med range, but it is only the intensity that is different ... obviously using a cheap Logitech G920 I chose the values for the Low/Med range but I indicated in the file what to change for DD and High (only 5 voices would seem particularly different).

About the file ... Karsten's original takes data from physics, when it serves all 4 wheels, but when it does not only serve 2, it implements some differences between the front and rear axles or between the front wheels and the posterior ones and simulates some posterior voices by taking the data from the previous ones ... finished everything develops its code by merging the results in the momentum rack and in the output ...

I have only extended the data collection always from all 4 wheels and not just from two, I have standardized the physics of the front and rear wheels only where this was different (grip and strech), and therefore not I simulate the rear with the data of the front but I take it directly from the rear because now calculated ... the rest does not change and everything goes into the rack and finally into the outpout.

 

@Michael Enright , @Roland Baltes and all with the problem of heavy wheel during curves ... i carried out some tests to reduce the lateral forces of the steering wheel when cornering at high speeds ... I found that, among others and after "velocity_res_scale", the item that most reduces the effect and the lateral force is the following with this increase ....

(vel_rot_limit_coef 1.40) ----> Original is 1.00

and with this above you should already feel the lightening clearly .... indeed you may need to fill your forces a little and only in this case let this item rise a little to rebalance (optional no mandatory)
(vel_rot_scale 1.20) ----> Original is 1.00

Only for correctness should be specified that this is a setting that is used in a more extreme way by @Danielkart with values of 1.50 for the first item and 1.25 for the second ... but I find it applicable to the low/med range without problems in size 1.4 and 1.2!!!

Let me know if it helps you, if you apply them both or only one and with what value ???
You can test this on any file not just mine, the rule is the same ... because, if I'm right, maybe we can also standardize this weight and speed characteristic between both DD/High and Med/Low wheels ...

Thanks in advance and good night to all!!

 

Hello, everyone!
Unfortunately I haven't been able to test Stakanov's new custom yet because I'm on vacation until tomorrow. Yes you can increase the (vel_rot_limit_coef ) and (vel_rot_scale) values. With (velocity_res_scale I would not go below 0.3, you lose a lot of information as a result. Tomorrow I will try to eliminate this hard and heavy without losing this fantastic feeling. Good evening

 

Thanks Stakanov. I will give it a try a bit later.

 

After initial tests with Stakanov's file, I can confirm the hardness and heaviness of the steering. But I already have a solution for dd wheels. It will be a combination with some changed values. If I can, I'll post these changes to you today. The commuting is still too extreme at dd, but that shouldn't be a problem either. And the 3 point is the very big bouncing of the cars, also on the curbs. But everything is easy to improve, I hope I can post you a suggestion for dd wheels today. Then Stakanov can customize it in his custom
Many greetings

 

Sure you can Daniel .... for now the curbs I have already reduced a little and also the two parameters for cornering hardness ... i still WIP for yours and Michael suggestions ...

(kerbs_surface_scale 7.8) -----> Original 7.5
