I remember I was doing similar research some time ago. I believe StateAttibutes affect dynamic barrier indirectly. Dynamic StateGraphs (ie those including dynamic StateAttributes) propagate their _dynamic value to associated render leafs. See StateGraph::addLeaf method. Sounds like you still investigate multiple monitor performance loss ? I am also very interested in your results....
