Hi Gianluca, The OSG just passes state along to the OpenGL, the glHint support is just another means to setting OpenGL state. How the OpenGL driver responds to the that State is down to the driver/hardware. In the case of line smoothing I believe that you still need to enable GL_LINE_SMOOTH even when using the hints, the mode simply enables the use of filtering that the hints specify.
