Just a question: how many fractures could i5/FX tolerate? Just an estimation…
Woa. So unbelievable many things that were ‘hidden’ before become available.
wow!!! This is fantastic! 
Is it possible to adjust the threading layout of UE4 to provide more theads to PhysX so that you get more physics performance? I have a game which is physics stacking heavy and I want to balance resources towards that particular problem.
Are you already using the ‘async scene’ I suggested above, and setting ‘use async scene’ on physics objects? Did you notice any improvement in physics time?
