Loading up a (specific?) 1.12 world in 1.13 renders the world laggy and unplayable. Setting the render distance to minimum and leaving the world to process for five minutes shows no sign of improvement in world performance.
Creating a new 1.13 world immediately shows good performance.
Attached are videos demonstrating both of these tests, as well as a world download that has not been opened in 1.13.
World | World Create/Upgrade Time | Door Close Time |
|---|---|---|
1.12 (Upgaded) | 44 seconds | ~ 9 seconds |
1.13 (New) | 17 seconds | ~ 1 second |

@DaUltraMarine Unclear, although it seems related. I'm not experiencing most of the issues they list, just the tick lag. My FPS is fine and the chunks are all loaded in during this.

I experience this too on all of my 1.12.1 worlds. letting the world process doesn't seem to do much on my laptop.
Is this the same as, or relates to MC-132135?
