--- Comment #25 from Stefan Dösinger stefandoesinger@gmx.at 2007-09-11 14:29:32 --- Guessing from the errors in #16, it might be that the application draws pretransformed vertices with a ps 3.0 pixel shader bound that expects the varyings passed in from the vertex stream. This will require a pipeline replacement shader, although it should be quite simple for pretransformed vertices.
I'm downloading the demo, maybe I see what is going wrong there.
