Paraview very slow (openfoam installation)

If I run ParaView (5.6 64 bit) installed with the OpenFOAM installer and run it from the command line it is very slow (rendering .stl or other larges meshes).

I downloaded the precompiled version from the website and that runs very well and appropriately fast.

Any ideas why and how I could fix that? Thanks.

Use paraview from, do not use the one from OpenFOAM.

Ok. I’ll do that.

Why? (Just for my understanding)


OpenFOAM version probably does not enable critical optimization component like SMP, maybe rely on mesa for rendering ? tbh this is a question OpenFOAM dev.
