I test performance of physics with new beta 12. My test is 500 ribigbody kinematic with sphere trigger collider and one child with a sphere trigger collider. Rigidbody can only detect child because of layer. So after the first frame, nobody moving. And physics continue to take huge time avr 8ms. So bug or normal ? And it's worse of course when I move all gameobject ( I use DOTween for moving GO) What do you think ?
