Progressive Caustics CPU Usage

[doppelgaengerdigital]

Whenever I switch over to progressive caustics, my CPU usage is 60% in average, with some small peaks to 100 and dips to 10 all the time.
I read in the 3Ds forum, that there is also this problem. Is this being worked on?

I am on Vray 6 and Threadripper 3970x.
