[Paraview] Paraview performance

[Claudio Silva]

What kind of rendering are you doing?

For volume rendering (and isosurface generation), HAVS can render up  
to 6 million tets/sec on the latest graphics hardware (single machine).

HAVS has recently been added to Paraview, and is also available stand  
alone:
