Thanks Alan. I used the wrong name. Render is the undesirable extension then for a "thin profile" of graphics adapter - for performance the graphics acceleration needs to be near the display, whereas for a stateless thin client it is not. Once upon a time Render was largely only used when available, now more and more functionality seems to depend upon it being available.
