I would be cautious with saying that BY-REF geometry has to be slower. In case of NIO-BUFFER, BY_REF geometry it can be quite fast. I have heard that in some cases vertex arrays are faster than display lists. This is certainly something to check out on particular configuration, but I would change this recomendation from 'lower one grade' to 'maybe lower one grade' - if data is NIO+BY_REF.
