Automobilista 2 Custom Force Feedback - Overview & Recommendations

Thanks , it was remiss of me not to do the same with Delta-X, so have added that above and in original delta post.
its still very good on my t300 without extra personalization.

 

Well done, Kuku. The original rFuktor 4.6 high end file with core Delta elements altered works like a dream on my Simucube 2 Sport DD wheelbase. It is my favourite custom FFB file at the moment, I even prefer it over the original unmodified rFuktor 4.6 file.

Also thanks for adding the high end file to your Delta-X package, I will try the Delta-X high end file tomorrow, I'll let you know then how it feels on my wheelbase.

Anyway, your file with the core Delta elements altered helped me to achieve another world record in AMS2 Time Trial mode after four months of break from AMS2. This time it was on Laguna Seca, I managed to beat the old WR by one second, which felt very satisfying. Links to the screenshots are below along with my in-game FFB settings and True Drive settings:

Wow, Kuku! You really did hit the sweet spot with your high end Delta-X tune version. It feels so natural! The biggest difference for me compared to the previous Delta tune is that catching slides have become easier thanks to the more natural feel which makes pushing cars to their limits more enjoyable.

I tested your Delta-X tuned high end file with various GTE car and track combinations - for example, the Corvette C8.R GTE on Laguna Seca, the Porsche 911 RSR GTE on Jerez Moto and the BMW M8 GTE on Nurburgring GP. Each of those combinations with the high end Delta-X tuned file felt just awesome.

I also tested it with the Formula V12 which is still my favourite car in AMS2 and oh boy, how well the high end Delta-X tuned file does it's job on this particular car. In fact it did so well that I even managed to improve the world record lap time on Laguna Seca in AMS2 Time Trial mode by one and a half tenths of a second which I've been holding since yesterday evening (did that with your previous high end file that had the Delta core elements altered).

I had to tune down the kerbs a little bit as my arms almost rattled of my body

 

@Kuku Maddog

I like the Delta X High End file a lot. Under-steer / over-steer response feels more natural and suits my DD-wheel settings very well. It's pretty amazing how such differences affect our perception of car handling in AMS2.

 

what wheel are you using Lars?
if a thrustmaster you might like to try running default control panel settings with spring and damper on etc.

I have trouble deciding what way to run it .

 

High end files great with a t500rs best file ever thanks for your hard work

 

Simucube 2 Pro
I use almost the same settings as tumi but with gain at 27

 

Great work Kuku! I adapted your 4.6 DeltaX values over to my G920 and it works smooth, gives me all the info I need, and it's transparent to the point that I don't really even think about the FFB.

 

Hi @Peter Stefani, I have a G25, got curious about experimenting your adjustments. Would you mind to share your G920 file?

 

I got a g29 and would like to try it too!

I see , well you have a lot of power in those things .
you might find some cars that are quite stiff and have a bit of downforce that pushes down on the front loading, causing excessive mid-high speed corner bump effects, particularly noticeable on historic tracks with GTE's etc.

One or two things you might like to experiment with is lowering the Bump weight .
(bump_feel_follow_weight 0.0)

and slight softening the tire stiffness.
(tyre_deform_stiff 1.20)

ideal values will vary depending on tastes and wheel..
These are just a couple of things I'm finding helpful as I fine tune my personal preset.

 

your tunes always throw up some really interesting and inspirational effects scales, that delve deeper than i ever think off.
i look forward trying out some to see what happens.

 

It’s all really just what happens if I press this button.
Seeing how it feels, and testing the limits of values, not that different to what you do with set ups.

Also looking down the file and seeing how it flows through various effects to try to decode the complexity for understanding.
I’ve read it so many times it’s almost starting to make sense.

I’ve possibly found some other gains here and there that I’m just discovering.
We have just gone into full lockdown for second time ever so having fun trying to see what else is there.

ultimately it’s for my own benefit, but doesn’t hurt to share.

 

Is there a way to enhance the brake feeling more as where in the weight transfer forward is more explicit?

Code:

# Dynamic adjustment to brake feel based on car weight
#

(brake_weight_scale           (/ 500 (/ (+ corner_FL corner_FR) 9.8)))
(brake_weight_scale           (+ 1 (* brake_feel_follow_weight (- brake_weight_scale 1))))
(brake_feel                   (/ brake_feel brake_weight_scale))

 

I didn't have time to delve deep into what Kuku actually did, but I do know that when I don't think about the FFB, (while driving) that's when it's best. Somehow it's just really balanced and controlled throughout all the ranges and phases of driving. Something with balance and blending.
I found with the DeltaX I was able to lower the FX a bit and still retain the same detail. Previously the FFB Histogram would generally be centered around the middle forces, but now there is more activity spread across the whole spectrum of the histogram, which would seem to indicate that the forces are more evenly balanced and controlled in their own relative force areas. Each car is different too, so it's quite interesting to watch.

 

Well you have hit the nail on the head with the term blending.
The key element was the change in the way centering works.
Previously it was like this, in a sort of predefined fixed value.

(centering 0.52)
(trail_strength_feel 0.13)

(force_scale (* 1.7 (/ 0.22 centering)))

but I always had a penitent for the blended system from older versions.
(trail_scale (- 1 (min 1 (* 3 lfb_slider))))

(centering (blend (- 1 trail_scale) 0.22 0.5))
(force_scale (* 1.7 (/ 0.22 centering)))

But the self alignment was quite variable depending on where you had your lfb slider set.
in 4.6 , the preset trail_strength _feel , seems to work well, so keeping that ( but its adjustable at same time in file and can lessen drag on wheel if lowered ), I found that incorporating the centering value into the blend formula like this , felt more dynamic.

(trail_strength_feel 0.13)

(centering (blend (- 1 trail_strength_feel) 0.52 0.5))
(force_scale (* 1.7 (/ 0.22 centering)))

It seems to self align more like real life. and reacts to velocity and wheel angle etc. so instead of snapping back at the same sort of speed and directly back to center it slows down as center approaches, You can test this by seeing what happens in your own car, its initially fast but then tapers off.
The actual value is up to each individual, I find around 0.42 best for my wheel, and with a slightly lower trail value.

PS:
Also if you like a more heavy wheel but dont want to upset the balance of rack vs effects scales etc at top of file you can increase the force scale in this line.

(force_scale (* 1.7 (/ 0.22 centering)))

and it will strengthen the overall it seems. maybe this is useful for lower torque wheels..

Found an issue with loss of useful feel with some cars , while others felt perfectly fine.
the variation in tires in Ams2 is tricky.
