MC-149239The loading/generation of chunks is a nightmare in 1.14
The bug
There are big performance issues with Minecraft 1.14.
A lot of lag spikes appear when the game loads and unloads chunks.
The generation is really very slow and some chunks do not even appear at all.
Sometimes, chunks can not charge at all or can flicker.
We have the impression that we came back in 2018 with the first snapshots of the 1.14 with the new rendering engine!
How was it done to regress at this point? Because it was not too bad in 1.14 Pre-Releases...
How to reproduce
1. Create or load a world in 1.14
2. Once in play, press Alt+F3 to display the lagometer graph
3. Explore your world and keep an eye on the graph

Yep, definitely an issue. I just updated to 1.14 from 1.13 and chunks load so much slower, I can outrun them, especially on a horse. I literally have to stop and sit still for multiple seconds for the ground below me to load. 1.14 is full on unplayable in its currents state of chunk loading. Good lord it's terrible, legit broken.
Same issue as
