The actors in unreal are such bloated single inheritance god classes that with a few actor components they take up more like a 4K memory page not part of a cache line, especially in editor builds. But they do have a more optimized entity component system now too. To be fair, a single transform now that things are 64 bit coordinates I think is bigger than a cache line too.
