    • None
    • 1.17.1
    • None
    • Windows 10 Pro 20H2
      Java(TM) Platform SE 8 8.02610.12
    • Unconfirmed

      What I expected to happen was...:
      game running as smooth as in previous versions when i summon bigger amount of particles

      What actually happened was...:
      game got really laggy, my TPS and FPS dropped  as soon as i started generating particles

      Steps to Reproduce:
      1. Make a datapack which contains 2800 particle summon commands
      2. Run it on 1.16.5 and any version above 1.17
      3. Compare performance



      I attached 3 files which I ran at the sime time using repeat command blocks
