Wow, I have to be honest I was skeptical at first, I didn't think this could improve the FFB that much but I only needed to race half a lap to realize what a game-changer it is. Using G29 and AC feels awesome now, racing feels so much more immersive now! Thanks a lot for your work!

Thanks for taking the time to write this nice message :)
Occasionally I went back to without a LUT and indeed, massive difference although it's really just a little curve for the few first percent of ffb output!
I wish you great fun with AC!

Takes AC to another level with my G29, simply astonishing!! Massive thanx for these LUTs. I've noticed with the 67 era F1 cars I get harsh vibrations while on the straight aways at Nords and other tracks. In the street cars and other non open wheel cars I don't have this problem. My gain is set at 50% via FFB clip and manual. Im using the "no clip but stronger" LUT

Thanks for the stars, glad that it works for you too! :)
I'll look into the vibrations and see where they come from!

Good tutrorial with a lot of info. Although I think everyone should generate his own LUT because every wheel is different (especially Logiteh) .

Does anyone know what exastly DAMPER_GAIN does in assetto_corsa.ini?

I spent some time looking for explanation, and just found different values recommended (usually 0.0 or 1.0) ?
In comments it says it should be changed to 0 for G920, but how about G27/G29 for instance since it's FFB is so simmilar?

Also while most people recommend Damper Effects strenth to 0 in Logitech Profiler some say it's better to set it to 70-100%?

The damper only affects the generic resistance while the low speed ffb kicks in so you'll have the feeling of scrubbing tyres like on a real car.
I like to have this light wheel though as I only do online racing and it makes life a bit easier to be able to spin the wheel freely while being in the pits/start/after spin. Just put it to whatever you want really :)

To the own LUT: I agree and disagree at the same time. Until today no one with a logitech wheel had to adjust my luts. The overall specs are really similar no matter the wear.
Did you try my LUT and if you adjusted something: please share the info in the support thread with your LUT :)

I think for when I used my g27 it was a game changer, the dull feeling when the wheel was centered whilst driving was gone.

I might be overexaggerating but it made the g27 feel more like a T150/T300 in terms of accuracy. Just obviously the g27 has a little less peak Nm to provide.

Thanks for this!

Thanks for the review! I totally get what you mean and I don't think you're overexaggerating. The default G27 feels quite awful in comparison, which hurts accuracy at turn in. It's quite weak though, definitely!

Thank you very much for your DFGT LUT! It is nice feeling on my wheel. Unfortunately my DFGT still have "center" notch. Or something like two rolls around current center. It may be not the true wheel center. I think it is mostly hardware issue with motors/wheel friction. But it disappearing with default settings with that sets low powers at center. In same time (in comparison my old "107" settings) your LUT is more soft. I like it! No more loud kerbs! I did only one modification of your LUT - removed light tremor when car is not moving (most first value - 0 | 0). I can't feel the difference in 0|0.070 and 0|0 settings. So I prefer not shaky wheel.

Thanks for the stars and feedback!
If the notch goes away with default settings you have too much force around the center. For me the notch also comes back when you remove the "tremor" as you call it. The wheel motors lose the "constant little energy" and you feel that hole then.
I'd suggest you put the tremor back in and just reduce the overall force feedback until the tremor and the notch fade away. That's what I always do with Numpad +/- for each car. + until the deadzone vanishes or - until the notch fades away :)

You, my friend, is a miracle worker. I bet a whole lot, if not the majority of us, do not have time to explore those settings until satisfied. You've donated your time and expertise into amplifying other's experiences. I hope I can make a video about it for my small YouTube channel so others can enjoy such exponential improvement. Thank you very much, I do really appreciate your work.

Thank you for that kind Feedback. One thing you got wrong though: I donated my time for MY experience :D (ok, the Guide etc. was for you <3 )
Don't forget to post me the link if you do such video! :)

Hello!

Haven't try it yet. In CM i don't have in AC inGame settings the options gamma, flter and sensitivity. In CM, at Post-Processing i have 2 sliders to set up. Center boost gain and center boost range. How i set up these? Bellow there are a checkbox "enable FFB post processing". If check it, it gives me 2 modes. One is Gamma and gives me to set up only gamma without filter or sensitivity. The second option it to load a LUT, the recomended one of your LUT. What i do?

Thanks for the write up i think i will try this! have you tested with a g25?

Thanks for the Stars :)
I only have a G27 and a friend has a DFGT. The g25 and g29 are pretty similar to the G27. If you click on the full guide thread (linked above), you'll see many people using these LUTs for their g25 or g29! :)

Thank you for this guide man, my G29 feels a whole lot different now. No huge deadzone in the middle and the ffb feels quite strong as it should be. I'm experiencing some problems though, I'd appreciate if you could help me out with these:
1- My wheel feels quite tight at the center now, with no deadzone, but if I let go of the wheel when driving straight it oscillates left and right. Its not enough to spin the car out of control, but it looks quite weird.
2- In some tracks I experience huge rattling when I first drive off. I think it has something to do with AC engine, as the larger the track, the most rattling I get from the wheel. It makes a lot of noise and its quite annoying, I would like to know if there's any way to fix it.
Thanks in advance man, in the meantime I will take a look at your detailed guide and see if I can fix these

Hi, thanks for the kind words!
About your problems: Try to reduce the gain. 10-20% depending on the car. Press minus on your numpad to change the ffb for your current car while driving and see if it gets better. If not, please read the post from the following link. It seem that your G29 has a bit more gain than others so you need a bit less "correction" from the LookUpTable. Summary: open the lut with a text editor, reduce first value by 30%, second value by 20%, all other values by 10%.

Great setup and guide. No deadzone whatsoever. However, i feel the steering ffb is still too lightweight for me. Is there any settings to increase the ffb power?
RasmusP
RasmusP
Yes and no. You're probably unhappy about the maximum force output of the kinda weak Logitech wheel. However my "recommended LUT" doesn't reach 100% gain. Also you can "fake" stronger ffb by keeping the average ffb output higher, while losing some fidelity. Like a modern dance song vs a classic orchestral rekord. Both are mixed to hit 99.99% of digital output but the dance song will feel a lot louder.
I worked on such a "fake stronger" LUT for someone, read on from my post here:

Im using the superstronglut because i do have a 35 cm steering wheel. And I cant tell you how much of a good difference it made, the car actually felt nice to drive! Although one problem that i have is that when im driving straight the steering wheel turns left and right really fast. Other than that its pretty good!

Wow, this is unreal I must say.
I got an old DFGT and bought Assetto for cheap a week ago. I been racing Gran Tourismo on and off for years but I really like AC.
Today I got mad not being able to find wheel setts I like, got lost between Profiler, CM, AC and game settings. Ten hours of tinkering later, read and downloaded your mod.
Ho ho, I couldn't believe the feeling, it's outwordly. I used to set my wheel for minimal movement, probably 280 degrees in profiler, this is polar opposite but it's fantastic.
I'm willing to try to get used to this setting, but so far, there's no way i can recover if I start spinning. Once off the road I can't even figure which way to turn the wheel..
You do normal racing with this sett or it's just for cruising or maybe drifting?
Should I put a spring on, so the wheel comes auto to it's default position?
Anyway, thanks for your effort, what you created is really cool, cheers.

Thanks for the review! I did normal clubracing and yes, in AC, if you start to spin you need to massively countersteer! With my current Fanatec wheel, it just does it automatically.. My old G27 needed some push to move around quickly enough. With the DFGT there's no chance sadly. It turns too slowly... So you need to actively turn the wheel into opposite lock, which is impossible at 900°. With the Fanatec wheel I just open my hands, lets the wheel rotate 400°, grab it again, wait for the car to correct itself and then let it rotate back and do a slight correction. With the DFGT I think you need to go down to 540° to be able to recover spins. Quite a nervous car then but at least possible to catch slides. My best friend has a dfgt and does only dirt rally, that's why I know this...
So: put the wheel to 540° and reduce the first line in the LUT files to 60% of the right value. I think this should work a lot better for you :)

Dude this turned my steering from feeling like a wet noodle for 30 degrees which then would transition into insanely stiff steering into something i more than enjoy driving. My Nissan Sentra had better steering feel .

Where before it felt nothing and then like i was hitting a barrier mid turn, and would have to guide the wheel back to countersteer, its now stiff from the start and smooth the whole way through. Its also auto rotating the wheel as it should. Recentering when in a straight line, and not needing to be helped along when trying to correct oversteer.

This truly changed the whole experience for me. Thanks.

Thanks for writing this review. Always makes me smile, when someone gets more enjoyment from his driving!
You describe exactly what this LUT is about and why I didn't stop optimizing it until it felt as it should :)

Thanks for this Rasmus, my old G27 was never feeling right with AC, but with this LUT (recommended one), I'm much happier.

Awesome tutorial, many thanks! Drifting now is way more fun, gonna try this also in racing.

I wonder if there is any difference on G29 - I think it has bigger deadzone than G27. I'm using your recommended LUT I am experiencing wheel wobble while driving straight when I give it a little touch. Any suggestion about it or it is intended to do so?
RasmusP
RasmusP
Thanks for the review :)
The wobble is a tradeoff for the tight feeling. Normally it should wobble but stabilize itself after a few shakes (if you just give it a slight notch and don't unsettle the car).
If it's too much you can lower the car specific ffb with numpad minus until it suits you better :)
