That might be related to other software running in the background and maybe doing something on the many files exported from realflow, for example virus scanners or automatic backup software? Does it also happen when you run the simulation in command line mode?

If you are using Hybrido, just disable OpenCL. The performance gain is just not worth it, judging by your UI lag.

If you are using Dyverso, make sure you try both of your graphic cards separately. I have two graphic cards as well, and I must always select the second one in order to avoid user interface lagging.
This is due to the fact that one of your graphic cards is already being used to display all the graphic elements in your screen.
