This is a practical dive into applying DOD (Data Oriented Design) to a bullet hell game, for a near 100% performance improvement. This achieves ECS performance without requiring ECS. There is a whole project I created to compare bullet hell in traditional Game Objects, looking at the difference for using a pool, and then finally, creating and running the same setup but in a DOD format.
Live performance capture in game allows it to run on the client, or at least display in game instead of IDE.
