Misc RasmusP's LUTs for G27/29 and DFGT 2.0

[RasmusP]

Thank you very much RasmusP

Waiting for your report

- how are the vibrations when standing still?
- does it feel tight and smooth while driving or
- is the wheel shaking too much
- not tight enough

With 100% gain in the menu there should be a per-car-gain level between 85-115% (numpad + and - while driving) with all original cars (no mods) where waving on a straight (constantly driving a bit left/right) feels absolutely smooth.
No "clack" when passing the center position and no "hole" in the ffb.

When standing still the wheelbase should make some "noise" and vibrate slightly but the wheel should NOT move on its own!!!
More like a cat that's enjoying some petting, not like a car engine being inside the wheelbase

Yes, i will do some more testing, but for now this is what i got.

In the pits, or standing still there is no shaking, no CAT that enjoys enything
IMO, i want it a tiny bit tighter, but it also feels very smooth at the same time. in general good response from the wheel in turns and overtakes.
There is some minor shakes, vibrtations when driving fast on the straits and the car can sometimes oscillate a tiny bit.
The center wheel have some deadzone and it "clacks" a littlebit turning right or left, it feels like it`s missing something in the center position. The ffb is not present before you get past the "clacks"
100% FFB feels a littlebit weak, but numbad FFB 115-125% makes it ok with some clipping present.

This was tested in ACC, With 100% FFB and:

"forceFeedbackGain": 1,
"steerScale": 1,
"steerLock": 900,
"dynamicDamping": 1,
"steerLinearity": 1,
"roadEffects": 0.20000000298023224,
"minDamper": 0,
"damperGain": 0,
"antaniGain": 0,
"minimumForceFeedback": 0,
"brakeGamma": 1,
"combinedPedals": 0

Without the Lut i use these settings with Trueforce at 100%:

"forceFeedbackGain": 0.95999997854232788,
"steerScale": 1,
"steerLock": 900,
"dynamicDamping": 1,
"steerLinearity": 1,
"roadEffects": 0.40000000596046448,
"minDamper": 0.25,
"damperGain": 1,
"antaniGain": 1,
"minimumForceFeedback": 0,
"brakeGamma": 1,
"combinedPedals": 0

Awesome!

If you want or still need it, A new g923 beta LUT is now up to testing. Feedback is essential

The zero ffb "noise" too low. (very first value of the lut)

There is some minor shakes, vibrtations when driving fast on the straits and the car can sometimes oscillate a tiny bit.

Too much ffb close to the center.

The center wheel have some deadzone and it "clacks" a littlebit turning right or left, it feels like it`s missing something in the center position. The ffb is not present before you get past the "clacks"
100% FFB feels a littlebit weak, but numbad FFB 115-125% makes it ok with some clipping present.

Not enough ffb exactly around the center.


Conclusion:
- Raising the first value
- make the curve go up earlier
- make the curve slightly flatter

I'll do some changes tonight or tomorrow

Sadly there's no real way of making the wheel stronger without clipping.
Your wheel is shaking a bit on straights, which means the there's slightly too high ffb at the end of the curved part of the lut.
Since it's a straight line from there, it's already enough gain.

Sadly you can't see the clipping after the LUT. The clipping meter sits before the LUT is applied...
The Logitech driver input has another clipping meter that we can't see.

So changing the lut to be as strong as 125% gain means the clipping is the same, you just won't see it anymore.

However, you can make the wheel feel stronger by making the lut curved all the way up to 100%.
That means you'll have more dynamic at lower ffb levels and less dynamic close to 100% ffb.

Can feel great! It screws a little bit with muscle memory though.

Modern power steering works similar though..

Anyway, I'll post 2 luts in the next days. One "normal" one and one that should feel stronger

 

[RasmusP]

As promised, 2 adjusted LUTs for you to test

Here's the Beta1 again:

Beta2:

And the very experimental "stronger" one:

Curious about your feedback!

 

[Knarfex]

Perfect! Will test them later tonight or tomorrow

 

[Knarfex]

Ok. Lets start with Beta 2:

I really dont know about this one!
From beta 1 to beta 2 I`m not feeling any remarkable difference.
No vibrations either, standing still. I will do one more test later, if you don`t change it.

Ok. Lets talk about the very experimental "stronger" one:

This is the LUT! For now...
- Still no cat/vibrations here standing still.
- Minor to none vibrations at the straits, but noticeable less compared to Beta_1. I kinda liked it
- It feels tight, the resistance is good.
From the center pos turning left or right the deadzone is almost eliminated. Yes, i can feel a little bump/clack/grain early at the turn from center, but after that it is nearly perfect and smooth, IMO! The FFB hits you early, and i like it!
I will most definitely recommend the stronger one!
In game settings recommendations? I will do some more tests, but this is what i had time for tonight!
To other G923 user out there that want to try the luts, please do so and leave a comment

They most likely upgraded to Fanatecs or something, lol...

 

[RasmusP]

Thanks for the feedback!
I'll leave the LUTs as they are then for now. If you find over time that you'd like something different, just make another post!

I'd like to wait for others with the G923 to test these until I'll add it to the download pack.
And also wait a few weeks for you to drive multiple hours with it. I adjusted things a lot over a period of a few months, this stuff takes time...

Very happy that the first try of the curved one is to your liking! It's similar to the "gamma like lut" from the package, with less force around the center compared to the G27 one.

I'm not sure if the last bit of smoothness around the center would need more force or less force. It's very difficult to figure out..

Does it become better when increasing or decreasing the gain?


About ffb settings:
Not really anything to recommend apart from what's on the download page.
Slip and ABS can be put to 0 if you don't like the rattling. It's completely fake and just additional feedback to know what's happening.

- Logitech Profiler:
- overall: 100
- untick center spring, NO combined pedals, 900° rotation, TICK "allow game to adjust settings"

- AC InGame:
- Gain: 100% (75-125% In the CAR)
- Filter: 0
- Min Force: 0%
- kerb: 1-5% (unnecessary vibrations, Kerbs are real 3D in Assetto)
- road: 2-10% (5% is enough to give you some subtle vibrations on surface changes)
- slip: 23% (important to feel spinning or locking wheels!)
- abs: 23%
- understeer: untick (unrealistic, only good for learning)
- Steering Settings: gamma 1, filter 0, sensivity 0!!

[Assetto_corsa.ini:]
- DAMPER_MIN_LEVEL=0.0: This means, that the InGame dampening is OFF, when the Engine doesn't send damper signals. If you increase this settings, your dampening will ALWAYS BE ON, even if the engine does NOT give the input for it.
The G27 delivers already very few details so you don't want anything to be dampened!

NP man dont stress it. I'm amazed that you did in fact made one or more just like that! Kudos to you.

Yes i'm agree. I hope others will test it also.

Hey, Rasmus! How are you doing? I just came by to tell you thank you for the LUT files, seriously, they are great!
I was a little underwhelmed with the g920 one when I tried it at first but now after using the one you made for the g29 (no clipping but stronger) I can really say it breathed some fresh air on my g920. The wheel rocks a lot left to right if you let it go on straights but it doesn't move at all if you are gripping it.
Thank you, my friend!

EDIT: Forgot to mention I own a g920, at least explicitly.

Thanks for the positive feedback!
Always makes my day when I hear that my work made someone happy

If your wheel is shaking, you definitely have too much "anti-deadzone", but if you're enjoying it, who cares hehe.

If you want, do the min force test from wheelcheck a few times in a row and post the results and I'll check if your g920 is a bit different than the few other g920's I got information from.
Maybe I can adjust a few things then

I don't really know if by sharing the results would mean sending the files over or what, I hope I did it right hahah

After running the test it says at the bottom: "Your maximum value for steeringFFBBaseOffset is 0.5% (50)"

 

[TheBoringDuck]

Hello, I generally had minimal vibrations/shaking when the wheel was centered and the car stopped, however something happened recently and the wheel has been shaking very intensely even while stopped. i tried all of your settings and am still having this issue. any ideas?

What wheel do you have exactly?
This sounds like the overall ffb strength in the wheel software got raised.
With the g25/27 and dfgt you have the old profiler with the overall strength slider.
That slider should NEVER be at more than 100%.

With g29/920/923 you have the new software or g-hub and I'm not sure if there is such a setting.
I know you have "sensitivity", which needs to be at 50%.

Other possible reasons could be the minimum force setting being higher than 0% or your rotation degrees being lower than 900°.

There's also this "experimental" automatic hard lock setting in content manager, which automatically changes the rotation degrees in your wheel. That needs to be DISABLED!

Hi,
sorry it took me a few days to do a mforce test with my wheel (csw 2.5) to compare the data.
Your mforce test shows wheel movement one step of "50" later than my fanatec wheel, so 0.5% makes sense.

The g27 and G29 have a deadzone of 13-16%!!
The issue is that the G920 has the identical hardware inside so the 0.5% deadzone are achieved by raising the gain internally about 15%.

So in theory the G920 doesn't need any LUT or min force setting. It basically has no deadzone.
However it has the same issue with the smoothness around the center like all Logitech wheels have.

That's why my G920 LUT looks like this:
The straight line = default ffb
Curved line = LUT ffb

It just makes it all a bit smoother without making the wheel shake.


But it all doesn't matter since you're enjoying the "recommended" LUT

If you're using Content Manger with Custom Shaders Patch (CSP),
you could also try to use the G920 LUT but then use 300% "Range compression" in the FFB Tweaks" extension.

The Range compression simulates power steering. Basically giving you more ffb around the center. But in a nice way instead of simply raising the gain.

Would look like this:

Merhaba,
deneyebilirsin!
Görünüşe göre bazı g920'lerin kazancı daha yüksek ve başka bir lut'a ihtiyacı var ama bazılarının ihtiyacı yok...
Bu garip.

Ancak böyle bir g920'niz olup olmadığını deneyin. Noclipbutstronger'ı deneyin ve direksiyonunuz deli gibi titriyor ve titriyorsa oyunu kapatın ve g920 lut'u deneyin.

bende de g25 var Ancak direksiyon çok titriyor. Örneğin hızlı giderken direksiyonu bıraktığınızda hem titrer hem de direksiyonu sağa sola sallar.

Please post your settings. This shouldn't happen!

It could be:
- less than 900° rotation
- more than 50% gain in AC
- more than 100% strength in Logitech Profiler
- Minimum force not 0%
- Range Compression in the CSP FFB Tweaks too high

 

[OmerT]

Hi,
you can try!
It seems that some g920 have a higher gain and need another lut but some don't...
It's weird.

But just try out if you have such a g920 or not. Try the noclipbutstronger and if your wheel is vibrating and shaking like crazy, close the game and try the g920 lut

I have the g25 too. However, the steering wheel shakes a lot. For example, when you let go of the steering wheel while going fast, it both vibrates and swings the steering wheel left and right.

 

[OmerT]

- less than 900° rotation
- more than 50% gain in AC
- more than 100% strength in Logitech Profiler

- Range Compression in the CSP FFB Tweaks too high

Sorry I didn't see your message and sent it again. I got a very nice setting right now, but the steering wheel shakes when I release the steering wheel while advancing the car.

 

[OmerT]

Lütfen ayarlarınızı gönderin. Bu olmamalı!

Olabilir:
- 900°'den az dönüş
- AC'de %50'den fazla kazanç
- Logitech Profiler'da %100'den fazla güç
- Minimum kuvvet %0 değil
- CSP FFB Tweaks'deki Menzil Sıkıştırması çok yüksek
