Logitech G29/G27/DGFT Force Feedback LUT Settings

After the v1.0.2 update, force feedback post-processing is now available for Assetto Corsa Competizione, just like in the OG Assetto Corsa. Making it possible to adjust and to create a better force feedback profile for each steering wheel.

In this guide I'll be using RasmusP's Logitech G29/G27/DGFT LUT for Assetto Corsa to be implemented in Assetto Corsa Competizione.

LUT Profiles

First of all, download RasmusP's LUT on RaceDepartment here.[www.racedepartment.com]

There will be four available profiles for G25/G27/G29 and one for DFGT, in this guide the recommended "NoClipButStronger" LUT profile is used.

Enabling Force Feedback Post Processing

Locate your Assetto Corsa Competizione configuration files in "C:\Users\%username%\Documents\Assetto Corsa Competizione\Config".

Inside, put a .ini file titled ff_post_process.ini, and the .lut profile in as well. You can find these files inside the downloaded LUT profiles.

⠀
The ff_post_process.ini will need to contain these following codes to enables the LUT:

[HEADER]
VERSION=1
TYPE=LUT
ENABLED=1

[GAMMA]
VALUE=1

[LUT]
CURVE=G25+G27+G29_NoClipButStronger_recommended.lut

Adjusting In-game Settings

Then, through the in-game control settings adjust the force feedback gain to 50% (when using the "NoClipButStronger" LUT profile), minimum force to 0%, dynamic damping and road effects as default to 100% and 20%, and steer lock to 900°.

Disabling Damping Gain

What you can't do through the in-game settings however is to disable the damping gain. Inside the configuration folder, open up controls.json and set these following values:

"minDamper": 0
"damperGain": 0

With controls.json, you can also adjust the previously required in-game settings with these following codes:

"forceFeedbackGain": 0.5
"steerLock": 900
"dynamicDamping": 1
"roadEffects": 0.2
"minimumForceFeedback": 0

Logitech Profiler

For the Logitech G27 profiler, set the overall gain to 100%, spring to 0%, and damper to 0%.
Disable center spring and combined pedals. Set the rotation to 900°.
And allow the game to adjust the settings.

*Ignore the not 900°

Do the same for the Logitech G29 gaming software, except that you can't adjust the gain.

Closure

Regarding the controls.json, you could keep the damping gain to be at the default value. However, personally me and RasmusP felt that doing so will gives the wheel a cringy standing still "rubber" effect, even though that it'll be inactive when you drive more than 5 km/h.

Dynamic damping is said to works constantly as it'll make the wheel felt heavier to move along with the vehicle speed raising. You could feel a bit more details by disabling it, in the cost of having the wheel to vibrate when going through straight at high speed.

Keep steering linearity to default as it's used for game pad configurations.

We also have no idea what "antaniGain" is... (Hmu please). Possibly an automatic center position reset or an understeer effect gain?

In the end, you can adjust the configurations into your suitable liking. Particularly, the damping gain and dynamic damping value.
⠀

Bonus

Personally, I find the brake feels better for my Logitech G29 by adjusting the brake gamma to 1 and limiting the brake maximum range to 90%

You can adjust them via in-game settings or by editing the controls.json codes below:

"maxRange": -0.8,
(Under the brake axis code)

and

"brakeGamma": 1,

All credits goes to RasmusP for making this awesome Assetto Corsa force feedback LUT!

can you not make this work if you dont have the original ac? cant figure out how to install content manager lol

[Fabalas]

ty, game changer

[HePE27]

OMG what is this wizardry?? I have just shaved off 5 seconds off my personal best in Brands Hatch... and my consistency is night and day... I am using the super strong version and wow just wow.. I thought it was me that's the issue apparently its just my steering FF settings that messing me up..

+1 game changer for the G29! Night and day difference, thank you!

THIS NO LONGER WORKS THE PORSCHE FEELS FLACID WITH 0 FFB

[Hipster Dufus]

Well Done!
A literal game changer for the g920

[Wazi]

+1 for the g29

[Winescomi]

i installed it, this is incredible, my times today im 2sec faster on the tracks, i was already about to throw away my g29

Thanks for your answer Krassmus. Finally it is working again, after installing an older version of Logitech G HUB. ACC experience is better then ever :)

[ΜΣ†ΛĿ]

just tried following this guide got as far as downloading the file "RasmusP's LUTs for G27/29 and DFGT 2.0" it now has a "RealNew80LUT_New_Recommendation" and in the old profiles there is a "Old_50gain_NoClipButStrongerRecommendedLUT" it seems like settings for the new recommended profile are different than this guide. did anyone compare the 2 profiles?
for this guide to work I should used the "Old_50gain_NoClipButStrongerRecommendedLUT" correct?
