[Paraview] to be sure about used hardware ...

Okay. That makes sense because i have a Threshold filter in my
visualisation pipeline. If i use wavelet source then i could see the
"Volume Rendering Mode" and it is set as "Smart". So, using Threshold
filter might also reduce the performance of the volume rendering. Right?
Anyway, thanks for your suggestions and help.
