I am creating domino game where each domino is single actor, when quantity of actors rise over 400 fps is falling under 50. How can I solve this? In domino actor there is single function, which changes it’s velocity to make it fall faster.

There’s a few things I can think of:

  • Use an Instanced Static Mesh for the dominos.
  • disable physics & ticking on dominos and only turn them on when nearby dominos start falling.
