Would I be able to do some testing of you new shader as well? I couldnt convert your old one completely to directx 9, just the FFP part of it... it seems to run a bit slower than the pixelshader/vertexshader version of it. I cant seem to convert the pixelshader version of it right. Also, while I got the FFP version of it working right I cant seem to get the textures to change there uvscale independantly. Hope your new shader will be able to do this stuff - Thanks, I also appreciate all the hard work your putting into progressing shaders in 3DGS!!
BTW - Steempipes FFP shader edited slightly to work with DX9
