[Paraview] Rendering Backend OpenGL2 & PV 5.2.0-RC4 & SurfaceLic --> Problem...

[Andy Smith]

Ken,

You are correct in your assumption about my dataset; it is multiblock
unstructured data.  Adding a MergeBlocks filter to my slice does improve
the 5.2.0 with OpenGL2 significantly.
With that change the performance of 5.2.0 with OpenGL2 is on the same order
of magnitude as 5.2.0 with OpenGL and with 4.4.0, though the 5.2.0 variants
are still slower than 4.4.0.

I realized after posting that my comparison is not exactly apples to apples
- my build of 5.2.0 required updates to mesa (13.0.0) compared with the
version I used for 4.4.0 (11.2.0).
I will recompile 4.4.0 with the same mesa version I used with 5.2.0 and
report back.

Thank you for your input.

-Andy
