Hi, my question is pretty self explanatory in the title. Basically, I want to check if a specific part is completely inactive, not interacting with anything, then anchor it. I’m trying to do this to reduce lag and increase performance, but I’m not quite sure how.

Roblox handles this on it’s own.

[Activated!] Sleeping Part Behavior Improvements

We have some behavior improvements to the physics engine ready to test now in Studio! What’s a sleeping part? The Roblox physics engine, like many others, uses a “sleep” system for simulated objects. Basically, when a part comes to rest, we mark it as “sleeping” and stop performing physics calculations, which freezes it in place as if it was anchored. Then, one of many different events can cause that part to “awake”, and begin performing physics calculations again. All of this happens in the …
