[Paraview] Paraview ray tracing plugin | OSPray

[David E DeMarle]

Definitely shouldn't do that. The rendering speed should typically be about
the same as you get with OpenGL but there are many dependent factors to
that of course.

Is that with the 5.0.0 binary or the recently released 5.0.1 binary? We
fixed a bug in between 5.0.0 and 5.0.1 that is the likely cause. Other
things you can try are to disable Progressive Refinement and to build
ParaView from source. All three have been helpful to others on the list.

thanks
