Tyflow too slow to simulate

[VickyVey]

Hello there, 
I was busy working on other projects. Did another test, which I have attached.
We updated the Open CL drives today but it's still slow when I activate the following operators: cluster, particle physics and Particle Bind.
Hope you find out what is going on... I am working on 3dsMax 2018.

Thanks again.

Another thing: once it starts updating all frames, it's very difficult to either pause it or cancel it... it simply ignores me pressing "escape" or "shift+esc"
