Can anybody explain me, why nodes from dx11 doesn’t have inputs or outputs?

maybe you missed to install DX11 nodes, or something is wrong with your installation.

directx11-nodes-alpha

another reason might be, that the names of the nodes has changed. in that case double click the nodes and replace them with the new candidates.
