Help with my steering deadzone

Hadn't played AC in months so I had several updates to install. I immediately noticed a difference in the handling. I have a G27 and they aren't the greatest I know, but with the updates my formerly annoying pedals felt AMAZING. The ffb is also much improved. The only issue I have( which I didnt before) is an annoying loose dead zone. I have added some "minimum force" but it is still there. I DON'T want to add "centre spring" so is there any other way to adjust this? Otherwise this feels amazing.
thanks for any assistance

 

Hi mate ,

The only other way world be lut gen ,it flattens the ffb signal and makes it more linear ,don't usemin force after ,instruction is in the link too

Thank you. I have never heard of this. I will give it a shot.

Appreciate the help.

 

Also adding a little damper effect can help. If you go for LUT make sure you have all the settings set before using it otherwise you start to screw up the FFB.

 

Also, be aware that each time AC is updated certain .INI files are "factory reset". Areas which people (me) often change and forget are:

assetto_corsa.ini
[FORCE_FEEDBACK]
FF_SKIP_STEPS=0

[FF_EXPERIMENTAL]
ENABLE_GYRO=1
DAMPER_MIN_LEVEL=0.01
DAMPER_GAIN=1

[AC_APPS]
ENABLE_DEV_APPS=1
SCALE_STEP=0.1

[CAMERA]
ALLOW_FREE_CAMERA=1

graphics.ini
[DX11]
MAXIMUM_FRAME_LATENCY=1

I know I always forget I have changed these lines, and after each update I'm like WTF happened to AC?

 

With the G27 there's the magic number 107 for the Logitech driver gain percentage. This will minimize the center deadzone as close as possible to the physical root cause. I have had a G27 briefly - the min force slider can't do it this well. Then you're wheel will have a non-linear response and you should compensate for that with a LUT.

 

The LUT is designed to remove the deadzone though - 107% in the Logitech Profiler shouldn't be necessary. Personally, I believe you should follow the suggested steps to find the most linear response for your wheel and go with that.

 

I was just adding my experience. The LUT doesn't do anything else than adding a min force. And from my experiments with min force on the G27 I know I didn't like that, at all.
OP can make his own decision based on all the experience in here.

 

I'm sorry, but it does do more than change the minimum force.

It completely linearises the force response for the wheel. Yes, it does remove your deadzone, but it will also ensure the force at the wheel increase smoothly from 0% to 100%

Adding 8% minimum force to the curve below would not fix the response.

 

Try my settings from signature. Actually, thanks to little damping and Atle's Anticlipping Tool seems I have no deadzone at all, without using LUT, minforce, and especially 107 in Logitech profiler which gave me very strange and unnatural FFB

 

Sure it does more than do away with the deadzone. I know that as you can extract from my previous posts where I suggested LUT for helping with the non-linearity that comes from 107 % in profiler.
Please read my posts more thoroughly if you want to discuss.

LUT deals with the G27 deadzone by increasing the low end forces coming from AC. It boosts the 0 - 9999 DX value sent to the wheel. This is also what the minimum force does. So that's your similarity right there it's the same mechanism.

However, when you adjust the driver through Logitech's GUI, you alter the hardware behaviour of the wheel and leave the raw FFB DX values untouched. And therefore you're treating the issue closer to its root cause. In theory, this is IMO the better approach for dealing with the deadzone.

When I had the G27 I had identified the most linear gain setting with wheelcheck and added the minimum force in AC, accordingly. But it wouldn't feel good. So I took the other approach and chose 107 % gain which is also recommended by Logitech support to minimize the deadzone. The wheel responded a lot better to small forces so I took the side effect of non-linearity as the lesser evil.
Now we can do both: deal with the biggest flaw of this wheel with the driver and then cure the side effects with the LUT.

If I still had a G27 I'd definitely try that solution, at least.

 

I did exactly what @LeDude83, did many many moons ago. It is, for me also, the best you FFB you'll get out of the G27. Obviously others have a different experience, but try all means available and pick that which works for you. I have even tried with Damper set to 10-30% but have gone back to zero. Try all the ways possible to skin that Dog.

 

Try to play, with damper settings in ac.ini. I'm really surprised how good and natural G27 FFB could be without LUT and min force

BTW. with FFB settings is like with partner - everyone has the best one

 

Tried it @marcinmarcin79, every time there is an update I make a nice new My Docs\AC folder, redo all setting and give it a blast for a few laps. Change a few things from what I had before then try again. But with the LUT thing I keep going back as I get a punchier FFB and can have more strength through the wheel. As you said, we all have it set the best.

edit: I also set my 'Max Count = 323' not sure how much of a difference it makes but I tried a few and I liked the results from 150 up, just ended up using 323.
