Issue: While storing "Roost"-chickens in "Storage Drawers" 2x2 drawers we are seeing a hugh FPS drop while looking in the direction of the drawers, we do not need to have line of sight. losing about 40 to 70FPS

Is it Repeatable?: Yes, by hiding/showing the item label with the"Concealment Key" we are able to toggle the issue on and off.

Mod/s Affected: "Roost" and "Storage Drawers"

They must be very expensive to render as item/blocks, is my best guess? E.g. if you put a bunch of them on bibliocraft shelves or other display blocks I would expect a similar hit to FPS, since they're rendered in realtime.

I don't have a near-term solution to this, researching ways that a label could be rendered/cached to another texture for render.
