Cloak waves too much

Good afternoon,
I’m new in cloth simulation and I’m having a bit of trouble with a cloak I’ve done for a character.

The main problem is, it just waves too much in the down part and non-stop (see attached picture), I would like to make it more straight and quite so that only the character animation influences it. I don’t find the parameter or parameters that would lead to that. I’ve try to add wind to sort of compensate the generalized weaving in the down part of the cape but it just don’t work. Any help would be appreciated.

Thank you very much,
