You seem to be confusing Draw Primitive with Execute Buffers now.

The irony of your question is that Draw Primitive was hacked into
D3D to ape OpenGL approach.

With OpenGL you also have the vertex arrays which allow you to draw 
from an array of data rather than repetative calls to glVertex, etc.

Cheers,Angus.
