Automobilista 2 Custom Force Feedback - Overview & Recommendations

Noticed, there's no more wheel selection required? Just checking.

 

Does anyone know please if there is a way to get rid of ingame clipping limit? There seems to be one. My DD1 isnt set to be too hard in this game but around 14-15Nm on high downforce cars I get sudden moments of "empty" feeling. It only seems to happen in high-DF formula apparently. Happens with both default and custom.

 

It is possible but not recommended.

One question first. What do you have your in game gain set to?

 

Im liking Gunboat Diplomat a lot thanks for your work.
Feels excellent with my G29 80/50/50.

 

Gain is at 60, but I tried even lower. And DD1 is at about 55 or 60 (out of 100).

It just seems that whenever game encounteres potential specific amount of force (not final output) it blocks details

 

Really like this file and find im faster with it on the high powered caterham.
I turned up the rack smoothing to 0.5 and the road noise down to 0.2

I actually find i can run with no Truedrive filters enabled apart from 15Low latency and ofc 1/10 recon filter.

For cars like the Formula vintage i have to run higher Inertia just to control the oscillation a bit more. You think thats something that can be normalized across cars in order for me to try to keep inertial filtering low / off for improved latency. I think cleaning the signal up in the engine beats doing it in post in the drive firmware although of course there will always be some upscaling.

I haven't been able to keep up with all the posts in this thread, what is the deal with the names for the files? What are the differences?

 

Gunboat Diplomacy v1.2 is very very nice indeed. best so far for me. It has taken a lot of the harsh steering rattle away which also means there is more useful sound vibrating through my rseat cockpit so rear end scrub is so much more noticeable now as well. All I feel is missing now is a little more centering forces and resistance to turning the wheel. Brilliant job @NuScorpii

 

The anti-oscillation works very well thanks! sorry for the late reply. I'm gonna try to fine-tune it now, but for reference, I lowered :
(scrub_scale 0.3)
(kerb_scale 0.2)
(gyro_scale 0.6)
in-game: 65.35.50 I might increase scrub a bit.

 

Which file are you running? There's 3 gunboats now.

 

So I have modified even more now and to my taste, it feels great! I think is the diplomat?
I can really feel the weight transfer, especially with the Sigma, freaking awesome to drive now.
In-game 70.35.50 - if you try it keep in mind I'm on 100FEI.

 

For sure man we are on the same page - thanks for giving that a try and ruling this out to confirm that the files are indeed affecting our T300 wheel bases differently with the same file/settings. This is very good information to have, as I never expected the exact same settings to give the same experience, but hopefully similar enough that we might be able to provide a baseline for others to work from going forward with this file.

Thanks mate for the feedback! It does seem that my wheel base is more sensitive to LFB than others. I don't know if wheel base age might make a difference, as I know internal parts are typically revised through the lifespan of these products. I have a friend with a T300 that I'm passing my files over to and he's getting very good results with my settings, which again, is interesting. I do think trying to find a baseline for the T300 might not be worth the time investment, as the range seems to be too great between the same wheelbase.

 

Hi @NuScorpii
This is my first forum post here, saw your comments on Ermin Hamidovic YouTube video, and have just tried your profile on my SimSteering2 on version v0.9.6.0 using your Custom V1.02, great stuff THANKS

 

Hi Can you attach the v1 file as there is just updated one now which I found very "grainy' with too much engine and road noise. Thanks.

 

here you go

 

Hey guys! Huge breakthrough today in the feel of the FFB when at the limits of the output. (@Shadak You're going to love this)

I have rewritten the clipping code so there is no hard hit. Instead it is using sigma functions to gradually taper off towards the clipping point. Each range of output is clipped separately so even when reaching the limits of the output you will still be able to feel the subtle effects such as road noise, scrub, kerbs, etc. This really has made a huge difference IMO, enough to warrant a new name

"Heavy Messing"

V2.0

* Completely new way of clipping the signal data using Sigmoid functions. This will enable high output gain to be used with very little chance of encountering flat spots in the force feedback.
* Bumpstop code changed to have a heavily damped buffer so there are no hard hits or bounce back.

 

legend! let me try this out

EDIT: this is absolutely incredible, no more empty FFB through half of Suzuka in F-Ult. This was probably my only ffb issue I thought might not get fixed .. Are you secretely Heusinkvelds FFB specialist or something?

 

@Renato Simioni Dude, I am sure this post will be of much interest to you; it appears user @NuScorpii has uncovered quite the bug in the default clipping code (regards the IF statement) as well as adjusted for safer collisions for those with DD wheels....someone buy this effing guy a beer already.

 

Just to expand on this, the "if" statement is expected to work like this:
if <statement> <output if true> <output if false>

However that is not quite right, it actually is:
if <statement != 0> <output if true> <output if false>

So both positive and negative values equate to true, only 0 goes to false.

This is used in the clipping code to give 30% headroom, however this only does the limiting to max of 30% when gain = 0.7

So

(headroom ( - 0.7 gain))
(clipTo ( + 1.3 headroom))
(clipTo ( if headroom 1.3 clipTo))

For low values of gain such as 0.3 when using high strength wheels will actually result in a clip to of 1.7, not 1.3.

This could potentially lead to huge spikes of output for DD wheels. This can be fixed by using:

(clipTo ( if (max 0.0 headroom) 1.3 clipTo))

However, the sigmoid clipping is even better

 

Update on the big file:

* Merged NuScorpii's latest front load effect over.
* Avoid clipping (using weights for full control, since this is the large file anyways & this allows 100% use on higher end-wheels with no transformation on ffb).
* Effects based on weights.
* Possible to change the weights with no chance of introducing clipping (also allows engine vibes to fill more, relatively when needed).
* Enhancements and effects normalized.
* Internal adjustment to gain/fx to keep forces in range & not in clip.
* Alternative slider control can be enabled :FX slider from ONLY RACK to ONLY FX - Makes blending effects weights easier when setting FX at 100 in this mode.
* Less harsh LFB values on road details.
* Road & effects LFB according to FX slider, not LFB slider, which is reserved for the big rack force only.
* Removed lfb from rumble & road vibes.
* Adjusted to soften lfb on road details.

In this file, now the "weights" at the top are used to adjust each effect, so please make the adjustments there.
