    I use a Logitech G27 Wheel when I play BeamNG.drive, and so when they added FFB it was a great improvement to realism.
    However I noticed there are some bugs to it.
    I KNOW IT IS AN EARLY FFB SYSTEM AND WILL BE IMPROVED, I AM JUST LISTING CURRENT BUGS THAT I'VE ENCOUNTERED.


    1. Sometimes, the wheel will center incorrectly when respawning the car. It will center slightly to the left or right.
    2. The feedback will be incorrect, giving a completely loose side and a really stiff side of steering. (ex. The left turn is REALLY stiff while the right turns like there is no force feedback at all).

    CURRENT FIX: The only fixes I have found is either to restart the game (as soon as I close out of the game it immediately fixes itself) or to open "Input Maps" on the main screen (it immediately fixes the problem and resets the wheel).

    It's not bad bugs I just thought I would mention them. :)

    Honestly overall the FFB system is really good for just being started and all.

    My main question is there a problem with my wheel settings or is this just a bug and will be fixed?

    Thanks all :D

    I have the same issue, but for me, turning to the right is stiff, and turning to the left feels assisted... well.. mine turns to the left on its own...

    and I'm also having the centering issue with my driving force gt D:

    Hello, I found the cause of FFB leaks a few days ago, it was also driving me crazy :) It will be fixed in a future update (probably not in the next immediate release, but one after that).
    Meanwhile, the only way to avoid it, is to reset/change the vehicle/level only when the FFB Graph app is reading close to zero ffb force.

    Here is another fix; Just open the Logitech profiler/gaming software, and go to the Device dropdown menu, and select Game Controllers.
    Then, Select your wheel from the list, and select Properties. This should fix the centering issue and the stiff steering.
    Its really useful on my end. Works with my Driving Force GT, should work with the G27.

    i barely get any FFB at all w/ my g27. does anyone have recommended settings?

    in logitech profiler i have:

    100/100/100 [all checked]

    0 [checked]

    900degrees

    allow game to adjust settings checked


    in-game i dont see an option for FFB strength but i could be missing it

    There is no UI options for FFB yet. You have to open gamefolder/lua/vehicle/hydros.lua and tweak the coefficients at the top

    Personally I use:

    Code:
    M.enableFFB = true --false

-- The direction of the real wheel's FFB
M.wheelFFBaxisdir = -1


-- The FFB Force coefficient
M.wheelFFBForceCoef = 300


-- The FFB steady force limits (in Newton)
M.wheelFFBForceLimit = 10


-- FFB smoothing
M.wheelFFBSmoothing = 300


-- High frequency FFB smoothing
M.wheelFFBSmoothingHF = 300
    However, others seem to use completely different coefficients.

    A good approach is to keep force limit at 10 or less, then tweak the force coefficient until the levels feel good. After that, reduce smoothing values from a high value (like 500) slowly to the lowest values possible without shuddering/jittering in the wheel.
