GameObject/Prefab inspector preview is slow for complex hierarchies

Inspector Framework


Game Object or Prefab inspector preview interaction is slow for complex hierarchies. For example, having a complex house prefab with about 10 thousand objects, the inspector preview runs at around 2 frames per second. Even if the same prefab in the scene view is interactive just fine.

- Have a complex prefab (say with 10k objects),
- Interact with it in the inspector preview,
- Notice that it's *very slow* up to being unusable.
