      The bug

      Rendering entirely empty chunks, containing no blocks or entities, still appears to impact game performance to a considerable degree.

      How to reproduce

      1. Create a new The Void superflat world
      2. Replace the central cobblestone block of the platform with a barrier
      3. Destroy all of the stone blocks on the platform using your preferred method
      4. Open the debug performance graph using F3+2
      5. Set your render distance to 32 and simulation distance to 5
      6. /tp @s 8 -60 8 45 0
      7. /tp @s 8 -60 8 0 90

      Expected results

      There would not be any noticeable difference in performance between the above two commands - in neither case are any blocks or entities loaded besides the player and the barrier upon which it stands.

      Actual results

      There is, in fact, a considerable difference in performance.
