Not problematic yet weird glitch about unanchored parts beign frozen while falling. (Rookie question probably)

As the title specified, it doesn’t really harm the game experiencie but it just doesn’t look right. This happens with players and NPCs where, for example, in this video, whenever a part falls or gets flung by an explosion just like in the video, sometimes it will just froze in time for some reason.

The part trayectory continues when you get close to it but then it freezes again once it gets far from the player or an NPC. This also happens when you or an NPC die-s, where accessories just float. The video above was just an example as it happens even when a npc or a player dies normally. Is there anyway to make it that falling parts continue their trayectory instead of freezing?

Another example:


I made that the body parts are massless for a better result and it happens the same.

Please ask for clarification in case is not clear enough, and sorry for my english.

This is also my second post in the forum so sorry if it there were any errors with the post.

Press Ctrl + Shift + F5 (FN + Ctrl + Shift + F5 if you’re on a laptop) and check your physics performance. This has happened to me before, normally when my physics FPS was low.
