To optimize performance when handling many dynamic Actors in a single Level in Unreal Engine, you can apply several effective techniques:

  • Use Object Pooling: Instead of constantly spawning and destroying Actors, create a fixed pool of Actors and reuse them as needed.
  • Reduce Tick Functions: Disable Tick for Actors that don’t require per-frame updates or increase their Tick Interval to lower update frequency.
  • Implement Level Streaming: Split your Level into smaller parts and load only the necessary sections.
  • Optimize Collision Settings: Disable collision for Actors that don’t need it, or use simplified collision shapes.
  • Limit Dynamic Lights: Reduce the number of dynamic lights, or use Static/Stationary Lights whenever possible.
  • Optimize LOD (Level of Detail): Ensure that your meshes use appropriate LODs to lower polygon counts when far from the camera.
