The discussion centers around optimizing Unreal Engine projects by removing multiplayer functionality and unnecessary components from actors, which leads to significant memory savings and enhanced performance. Users highlight that by eliminating built-in overlap events and other features, not only does RAM usage drop, but instances of ghost reads/writes are also reduced. However, caution is advised regarding the number of actors in a scene, as too many can burden performance despite the optimizations. Community members suggest potential instances where having large numbers of actors might be beneficial but recommend using more efficient methods like instancing or employing actor handlers for UObjects to manage performance. Additionally, the effectiveness of these changes in a production environment and their impact on performance relative to memory savings are raised as important considerations.
