1.16.3 vanilla server freshly generated amplified world, stutters are noticeable while walking with normal speed (a little less while sneaking). Easy to reproduce by flying back and forth in creative mode in amplified world.
It's much less noticeable on a recorded video though, even on 144 fps.
Noticed this for the first time today on Realms (game version 1.14.3). Will try to reproduce.
Harvesting leaves with shears also creates massive lag. I believe the root cause of the issue is the same.
Nope, someone stated this affects worlds created in 1.14 too.

Noticed just today: I'm underground but Sky light level is 15, and zombies start burning.
1.14 affected
It is in Realms too (it's the same release 1.14 after all). Is there a workaround for this case?
Looks like the launcher fails to find the Java runtime when the path contains symlinks or junctions.
I was experiencing the same issue. In my case bundled Java runtime was used which was at D:\games\Minecraft\runtime\jre-x64\etc... but in my system D:\Games is actually a junction targeting at E:\Games:
>dir d:\ | find "Games"18.08.2015 21:11 *<JUNCTION>* Games [??\e:\games]
So I changed the launcher shortcut to E:\games\Minecraft\MinecraftLauncher.exe and the problem gone.
C:\ProgramData\Oracle\Java\javapath\javaw.exe is a symlink so the new launcher fails to run the game on that too:
>dir c:\ProgramData\Oracle\Java\javapath\javaw.exe | find "javaw"17.11.2016 01:26 *<SYMLINK>* javaw.exe [C:\Program Files\Java\jre1.8.0_111\bin\javaw.exe]
I did a benchmark with older versions. Start time is time elapsed since javaw.exe process creation until the main menu appears AND javaw.exe cpu usage dies down to 1-3%. CPU time is taken from Process Explorer. I have 6c/12t CPU, so for example 100% load for 10 s would be 120 s CPU time.
