There are different issues here: the speed in which the geometry of an 
avatar is rendered and the speed at which the attachments are rendered.  
The code is separate.

I don't understand why an LCC, or any viewer, would need to tell a sim 
that it is currently rendering at a low quality. I understand with an 
LCC that it tells the sim not to send as much info that a viewer would 
normally get. In the end, the step to remove geometric updates does not 
actually increase render speed... it just lowers the quality as a tradeoff.

The vertex shaders help, but I still would like to see multiprocessor 
rendering threads.
