Automobilista 2 Custom Force Feedback - Overview & Recommendations

What's your Simucube DOR set to? Do you have bump stops enabled in the simucube software? I only get really bad shakes at the bumpstop when the game is hitting the bumpstop at the same time as the wheel software.

Try changing the lockstop code to this:

Code:

# Lock stops ----------------------------------------------

(custom_lock_stop 2.0)
(stops (bumpstop output 0.15 0.5 0.15 1.0))
(output (+ output (* stops custom_lock_stop)))

That seems to give a more consistent less shaky bumpstop.

 

Update:

Complete overhaul & simplified in a new series "Silver Raw".

* Momentum Rack 2.0. New simple full featured rack calculations.

Momentum Rack 2.0:

* Simple: Momentum & balance code in lines 91-111 (not shortened for better readability).
* Details/bumps/large features taken from "load" on each wheel, not from the rack.
* Balance working.
* Notch GONE.
* Both wheels included in calculations each on their own, grip, angular velocity and load.

Silver Raw 1.0 other stuff:

* Based on scales for getting the values "absolutely" correct when people report numbers.
* Adjusted values that should fit other wheels than my own.
* Might be the core for a last update to the more advanced "Silver Bullet" series, if I find the time.

Adjustments for features in the top of the file.

Start by Gain 70 / FX 50 and go from there.

FX slider adjusts:
- Rack: Details/bumps/road features.
- Effects: Road rumble/engine vibes/scrub.

If you want more of the turn/torque/momentum effect, raise the value for:
"momentum_rack_scale"

If you find the larger road features "too punchy", but you need high Lfb, then keep the high Lfb and remove the line that reads:

"(rack_large (lfb rack_large 0.15))"

This file feels incredibly fun, love it. One small bug I noticed is if I set the Low force boost to 0 my wheel goes crazy and starts to bounce from side to side.

 

Might still be the same issue/bug w/ Reiza if LFB=0?

 

Hey Karsten,

I managed 20 min here and really enjoyed it! Had to try hard to find places to improve.
For now, the only things I have changed in the file was engine noise when standing still lowered to 0.1 and scrub to 0.4. It was a bit too grainy with the V8 and sigma, but to me now it feels pretty damn good!

So far great file and overall well balanced, getting all the forces I wanted through the wheel, thanks!
Running: 70.40.35 atm.

 

Yes, thanks! it's fixed in the next version

Cheers

 

Update:

"Silver Raw 1.1":

* Adjusted friction, scrub & momentum rack strength(still 1.0 in settings, but stronger inside) based on feedback from @F.Santos.
* LFB 0 bug fix - Remembered to add it in .
* Adjusted loss of grip feel.
* Better self-alignment on loss of grip.
* Added kerb effect back in.
* Minor correction to balance calculations on grip loss.


Adjustments for features in the top of the file.

Start by Gain 70 / FX 50 and go from there.

FX slider adjusts:
- Rack: Details/bumps/road features.
- Effects: Road rumble/engine vibes/scrub/kerb.

If you find the larger road features "too punchy", but you need high Lfb, then keep the high Lfb and remove the line that reads:

"(rack_large (if lfb0Fix rack_large (lfb rack_large 0.15)))"

If you have a high end wheel and want more linear dynamic range, then lower the gain to keep as much of the ffb signal as possible within 90%(the fully linear part of the custom function that applies compression at the upper end to benefit all lower end wheels) and adjust your wheel base power up from there. It can make for a big improvement.

Quick question, what is the effect of low force boost in your file? Same as the default?

 

Same, yes, except it also allows the Lfb to the road features no matter if wheel is under load by other forces too.
The strength is set at the same 0.15 for both big rack force as well as large and bump features of the road.
Then for details a custom function is used based on fx.

So the lfb slider controls the feel of those large & bump features, which is not done in the Default.

If you want less spikey road features then lower the Lfb slider a little.

In the file you can also scale the road features. That way if you run low Lfb, but want some road features simply bigger you can change them there.

Real happy to hear about any adjustments that you might make!

Cheers!

 

Hey Karsten,
I am now using momentum_rack_strength at 1.15 and really enjoying it, very nice update! thanks mate.​

 

Great, thx for posting! Will try that too myself and update accordingly

Cheers!

 

Thanks for the update! Noticed quite stronger pull when hitting kerbs, what's the variable to adjust for this?

 

Really appreciate the excellent work you guys are doing here to make AMS2's FFB even better. After a few weeks away from the game I tried "Silver Raw 1.1 - Momentum Rack 2.0" tonight with my CSW V2. I hate to be 'that guy' who asks questions that might have obvious answers from reading earlier posts, but looking at least a few pages back I'm still not clear on what I should do:

I immediately realized that the constant vibration in my Formula V2 rim (seemed related to RPM?) and the massive kerb jolts would need to be dialed down in order to make driving more manageable. Is there a 'smarter' way to do this than just by lowering FX? I had to drop it to 10 to get both above issues down to levels that seemed acceptable. Could someone suggest some parameters I could try tweaking in the file to address these issues more directly rather than through the presumably brute force method of dropping FX, which I would imagine thereby removes other effects that I would like to keep?

 

Yes, Kerbs are ridiculously strong with this latest file (at least with an f3 car). I actually can't use the profile anymore as I kept spinning out because they jolted me too much. Reduced LFB quite a bit and was still getting that.

 

I tried reducing kerb_scale but kerb pull strength didn't change much. Still testing out others.
EDIT: kerb_scale to 0.01 seems better (from 0.3), though still bit strong w/ the Stock Car, quite ok with the F3 (w/ lowered overall settings of 70/40/50 from 80/50/50).

 

Try adjusting the kerb_scale to 0.1 in the file.
Then in game, instead of adjusting fx down, adjust Lfb down instead and FX up again to maybe 50%.

Cheers!

 

@GregP I'm on 60.30.45 using a v2.5, I kept most parameters as they are in this file apart from momentum_rack_strength which I increased to 1.15.

I have the additional drift option to -2 on the wheel which I think you don't have right? If you have FEI other people were complaining about the games sharp FFB at 100, maybe try lowering that a bit too.

 

Yes, now lowered overall settings to 70/40/50 and set kerb_scale to 0.01 from 0.3 (from 80/50/50 w/ Nuscorpii's file). Nope, T300 doesn't have the FEI (or is that Spring or Damper?).

Try the Stock Car @ Donington, ride the kerbs to test. The F3 though seems ok, in contrast to the experience of @Pixel.

 

Yeah, It's Force Feedback Intensity, may not be applicable to yours.

 

Update:


* New kerbs effect. Now amplifies the signal from the relevant wheel, when on a kerb. This should provide more varied & correct feedback in most places.

* More fine controllable feel by FX and LFB sliders.

* Adjusted values based on recent feedback. Momentum rack strengthened to 1.15, thanks @F.Santos as well as effects not quite as violent in general(@sherpa25 @Pixel @GregP - hope this suits you guys better). It seems no wheel needs the crazy that was possible in v 1.1 , so better have it more fine controllable.

* LFB slider now used solely for the big ffb force. Experimental - Idea is that the LFB slider mostly should target the big force for steering. Getting a little closer to "Default" slider value to work well.

* FX slider controls all increases in road features and effects. Experimental - Idea is that FX slider should control all additional added stuff; road & artificial effects alike. Getting a little closer to "Default" slider value to work well.

* FX slider in "boost" mode above 70%. Here it will amplify the signal for road features more and more. The idea being that anybody above 70% will need an additional helping hand to get to where they want to be.

* FX slider controls also the low force boost level of everything except the big steering signal.


Note that you will need to adjust the FX slider from the last version. Start by:
- Gain 70
- FX 50
- LFB as you would use in "default"
and go from there.


With this update, hopefully everybody will be able to get most of what they want from adjusting the in game sliders only.

FX slider adjusts:
- Rack: Details/bumps/road features.
- Effects: Road rumble/engine vibes/scrub/kerb.

LFB slider adjusts:
- Only low force boost on the big steering signal. Just like "Default".

Additional adjustments for features in the top of the file.


If you have a high end wheel and want more linear dynamic range, then lower the gain to keep as much of the ffb signal as possible within 90%(the fully linear part of the custom function that applies compression at the upper end to benefit all lower end wheels) and adjust your wheel base power up from there. It can make for a nice improvement when forces are going high.
