The feature is hidden behind an experimental option, you'll have to enable it in the preferences to try it. This feature is not yet considered fully stable, crashes may happen, as well as .blend file corruptions (very unlikely, but still possible). In a nutshell, the ideas behind this code are to: * Detect unchanged IDs across an undo step. * Reuse as much as possible existing IDs memory, even when its content did change. * Re-use existing depsgraphs instead of building new ones from scratch. * Store accumulated recalc flags, to avoid needless re-compute of things that did not change, when the ID itself is detected as modified. See T60695 and D6580 for more technical details.
