Visibility, Cloth Simulation and Performance issues

Hi everyone,

I noticed something strange while trying to optimize my game.

I have 4 Skeletal Meshes with cloth simulation on, and using Stat.Physics it is pretty clear that when my actors are visible the callCounts on Cloth are lower (?) than when I set them to hidden in game.

Does someone know what is really happening to cloth simulation when the actor is invisible?

I’ve searched and found some insights on how cloth simulation keeps going even if the actor is invisible, but disabling the cloth simulation when I set them to hidden (using either Disable Cloth Simulation var or setting a lower LOD without cloth) doesn’t have any effect on performance when actors are hidden: call count on Cloth stay high (while they are sensibly lower if I disable cloth when the actor IS visible).

Does that mean that a hidden actor is not always better for performances than a visible one?
Is there something else to do on an Actor to stop any Cloth Physics calculation?

Hope someone could give me some more info about this.

This is interesting, I noticed there is a performance issue when the cloth actor is hidden, even calling Disable Cloth Simulation
