TimeController question

I have a question regarding the TimeController.
NxOgre::TimeController::getSingleton()->advance(e.timeSinceLastFrame);
As I understand it, this call in an Ogre::FrameListener should get the PhysX System to work at the same speed at any given framerate. Is that correct? Because in my App it still runs much slower, when the framerate drops and I don't know what more to do about it.

Wich version of NxOgre are you using?

IIRC TimeController::advance does not work correctly in bloodymess, you should use detritus

Thank you. I'm using the git of blodymess, I'll try out Detritus.
