PhysX.BpSAP.updateWork 60ms (i5-8400)?

Got an issue with performance. Title.

Does anyone know what that BpSAP is? Or what might be causing this issue?

I've got a bunch of primitive colliders attached to the bones of animated characters.
(That have all collision disabled between each other / world via collision matrix)

Could it be causing this kind of issue?

 

Bump, UT?

 

Yes, it is caused by large collider count. I've just counted total colliders and it is 72 per entity (oof).

Albeit I was pretty sure there shouldn't be that much of an overhead while having all collisions disabled.

I guess they still need to be synced once they're moved by the animation.
And zero optimizations done for this use case.

30 x 72 == 2160 collider updates. Hmmm....

I guess I'll need to find different solution to limb based damage system. Or use less colliders.
Or by doing some weird tricks.

I wonder, if detaching colliders from bones / updating them once in like 0.5 seconds will help in this case.
