So splitting each quad in the quad strip down to single primitives/Quads and creating a normal pr. vertex would be faster even though it creates more data?

BIND_PER_PRIMITIVE_SET will require a norm pwer primitive set. BIND_PER_PRIMITIVE will force the OSG down on to OpenGL slow paths as non of the fast paths support this type of usage so I wouldn't recommend going this route. Robert.
