    Hello,

    I bought rFactor 2 a couple weeks ago and I still have troubles with the wheel feeling because it is very hard. It becomes very hard in the following situations:
    - When car is running slow or stopped; for instance when car is running on the pitstop.
    - Using GT or LM cars like Mercedes_SLS, Porsche, McLaren, Audi R8 LM, BMW Z5 GT3...
    - When the car is on the track and it starts to skid, this became very hard.

    I already changed a lot of parameters from logitech profiler and also inside the .json (old .ini) files controller to try to solve the problem, but the game doesn't works properly yet.

    The only way that I found to solve this problem is decrease the parameter "CAR SPECIFIC FF-B MULT 1.00" to lower than 1.00 inside the game, but I think this will decrease also the feedback of the physics of the car and track because in straights the ffb is very soft but in the curves it still very hard/heavy.

    I attach here my current setups:

    Can anyone help me to fix this problem to be able to enjoy this game?!!

    THANKS very much in advance!

    I guess you are speaking of BES mod.. best ffb multi value vary in each mod. BES mod has really strong forces so you have to use lower ffb multi value. I have T500 wheel and I use 0.32 multi with this mod. No too weak forces with this value. TM profile force is 60%. In most of the other mods I have ffb multi of 0.5-0.6. You should try higher steering torque minimum value in player.json. Search forums for instructions to set right value. It will make low end forces stronger so you can lower ffb multi without feeling numb in low end.

    I have a G27 too, and since that's a pretty lousy wheel compared to for example the belt driven ones, you need to apply some ffb smoothing. 2 is imo way too low. I run 12 for it to be tolerable, with the noise and heavy grinding of the wheel.

    Also have a look at the big ffb thread here on the forum. There's everything you need to know to avoid clipping and other bad stuff. Its a definite must-read to get the best out of a bad wheel.

    EDIT:
    Here's the link. Read all the way through the first post.

    Yes, I was talking about the cars of the "BES mod". I didn't know that all of them were so strong. I'll try to decrease the value of ffb less than 0.5. Thx!

    I read it before but there is a lot of parameters to test at the same time and, after try a lot, I decide to write this post ;)
    Could you share your setup?

    THX a lot for your answers!

    Try ffb mult. of 0.5 then go up or down at intervals of .05 from there.

    Here we go.
    Remember, the ffb multiplier in-game varies from car to car.

    No need, i know, rF2 is the best ;-)

    The only complaint i have, is about the very poor triple screen support...

    However, thanks again, keep racing!
