<pre>The most likely explanation is the overhead from computing the gl_client_arrays
in _mesa_update_state(). Lightsmark makes a lot of calls to glDrawElements()
each frame, and changes the vertex arrays between those calls.
That being said, I can't reproduce the regression with r600g. I get
approximately 115 FPS with and without the ARB_vertex_attrib_binding changes.
Could you investigate further?</pre>
