It avoids duplicate calls for pipe_vertex_elements refering to the same pipe_vertex_buffer.<br></blockquote><div><br></div><div>And the old code does exactly the same thing - it avoids duplicate calls for the same pipe_vertex_buffer, because vertex elements reusing vertex buffer slots don't have their bit set in first_vb_use_mask, so add_to_buffer_list is never called for those vertex elements.</div><div><br></div><div>Marek<br></div></div></div></div>
