[Paraview] Why Paraview runs much faster on Windows than on Linux?

[Weiguang Guan]

vtkVolumeTextureMapper3D is running on Linux at a speed comparable to on 
Windows, which is an evidence that the video driver on linux works 
efficiently. Is it possible that the driver does a good job at 3D texture 
mapping, and does a poor job at other graphics operations?
