Picking has been implemented by reusing the code from d3d_execute_buffer_execute() with the drawing functions removed leaving the core vertex processing and adding click tests for creating an array of D3DPICKRECORDs.
That strikes me as less than ideal. Which alternatives did you consider? Also, do you have tests to go along with this?

Hi Henri,
I would agree it's not very efficient, however I believe it is accurate to how the function is intended to work according to the SDK documentation.
The documentation says:
"The IDirect3DDevice::Pick method executes a buffer without performing any rendering, but returns a z-ordered list of offsets to the primitives that intersect the upper-left corner of the rectangle specified by lpRect."
I don't have any tests I'm afraid, I used the two games I mentioned to develop this patch.
