[Paraview-developers] accelerate ParaView graphics rendering speed

[Aron Helser]

Hi Chiranjib,
The 'legacy rendering backend' is referring to OpenGL 1.X support, which is
still hardware accelerated. However, you will probably get better
performance with the OpenGL 2 backend, which became the default in ParaView
5.2+. Can you upgrade?

On Linux, you also may have to take some extra steps to install graphics
drivers appropriate to your graphics card. If you can install those drivers
and confirm they are working, ParaView will use them automatically.

Loading time for a large file, 5 Gb, is determined largely by the speed of
the disk it is stored on. If you want to speed that up, have you tried an
SSD?
Hope this helps,
Aron
