So If anyone else have this problem, where the chunks are very slow in this version and lag on menu like for example settings.... Severs keep getting crashes than before.... I mean 1.16.100 is a lag fest. 1 command in the world.... Lag!   Singleplayer in a flatworld with no resource or behavior packs..... Lag! Pressing the Settings tab.... Lag! You seethis new version is causing more problems.... I cant have a image or video right now but I would later...
