[Paraview] Query on Paraview CPU vs GPU acceleration

It looks like your GPU build isn't actually building against the GPU.  In
order to use the GPU with the NVidia driver, you either need to use an X
server or use EGL.


-DVTK_USE_X=OFF

In this case, you have disabled X but not enabled EGL so you're left with
OSMesa when you really intended to use the GPU instead.  See
https://blog.kitware.com/off-screen-rendering-through-the-native-platform-interface-egl/
for more details on configuring ParaView to use EGL.
