So I started a world in 21w16a with the Caves & Cliffs preview datapack on. After leaving the world for the first time and restarting it right after, massive lag spikes would occur when I cross a chunk border.
Here's a link to a video I made showcasing this bug:
I just wanted to make a survival world and play a bit checking the new things out along the way and stuff, but this just makes it unplayable...
Environment
Java Version is the latest as of writing this.
I allocated 12gb to the snapshot, Minecraft was using about 8gb throughout the video.
The datapack Caves & Cliffs is enabled.
Memory : 32gb ddr4
CPU : Intel i7-10700F 2.90GHz
GPU : Nvidia GeForce RTX 2060 6gb
Resolution : 2560x1440 - Probably doesn't matter..
Anything more you want too know?
