Thousands of Unanchored Parts

I have thousands of unanchored parts in my game, which is lagging the engine a lot, the parts are in relatively close proximity from one another. All of the unanchored parts are client side (the parts aren’t spawned on the server side, so the server doesn’t know of their existence).
I’ve tried enabling Interpolation throttling and adaptive physics stepping, but this does absolutely nothing.
Is there an effective way to reduce the lag?
NOTE: Decreasing the amount of parts, isn’t a great option for me.

Why not anchor them from the client? If you want them to be unanchored, there’s nothing you can do to reduce the lag afaik.

Is there a reason all of them are unachored?
Can’t you change the behavior to unanchor parts you need?

yeah… unfortunately I need all of the parts to be unanchored, they’re only for visual purposes tho, so maybe I’ll try looking into particles…
