Unfortunately there aren't many new demos that would show new features of DX9. There is a displacement mapping demo, a demo that uses static flow control of VS_2_0 to pack standard D3D lighting into one shader, and there is a depth of field demo that also uses PS_2_0 shaders.DaveBaumann said:The MS SDK should have some executables in there as well (hopefully - if it been updated), and presumably ATI's SDK will have some in as well.
If you want eyecandy ATI demos are for you .
