It's the same for me too...I have had to turn down the Max Force in "force settings" on MMos to 45% and it is still very strong but better, I may even turn it down more.
It hasn't affected the feel of the ffb (that is still great) but overall strength has been reduced.
I am interested in your setting for rFactor2 though,,,pm me please if you can with those as I can't get any ffb coming through my osw for that...do you have to change any files within the games main folder ?
sorry for going off topic
