Yeah when I switched to the pc version stuff was way better and more comfortable. Maybe try using a virtual pen or something?
The reality of the situation is that even if a particle has no update function, it goes through the update loop anyways to handle heat and physics. There are *some* optimizations (Under a set of conditions, physics is skipped), but not much we can do.
tl;dr this is not a bug
Also, are you not natively english? If you're using Google Translate, just please don't.
It's recommended in the rules to use it if you don't speak English natively, I hope I am not misunderstanding you.
