If you can attach PIX then that will help track down any specific DX API call used to perform an operation or render
Thanks, I tried PIXWin, it works. The game calls SetTexture -> SetStreamSource -> DrawIndexedPrimitive to draw the text
I can see the Mesh, VertexBuffer and some other visual information from PIXWin, but I don't see any relationship between these stuff and the text being drawn. So I tried to analyze the Text3D from DirectX examples, because it uses ID3DXFont::DrawText to draw this red string(on the first image), and may be I can find the how the underlying things are done.
I captured one frame of Text3D, opened in PIXWin, it draws this line first:
and here's the call of DrawText:
I checked all the functions in the call tree, 0x010016F8 is never used, why? maybe I missed something?
Thanks.
