Hello,
I and some friends have noticed that when an object is grabbed in a world, it causes fps issues. In my world it becomes a complete slideshow and others drop it around 20-30 fps (Tested in Exoplanet and Popcorn Palace). This behavior started one or two updates ago.
Based on what I have messed with, if an object is strictly tied to your character, (Personal Mirror, Audiolink Panel) it lags a lot more that objects that "float" when you move them around (Pool cues in my world).
I have only tested this on pc. But it appears to affect desktop more.
