The Bug
When being high above the world and looking downwards, the framerate drops significantly.
I discovered this while testing 1.17's new world height customization option. This does affect 1.16.4 as well though.
In my case, FPS drop from ~70 to ~30.
My guess is that despite the world being out of render distance vertically, the game still tries to render all the chunks below at once.
How To Reproduce
- Be in creative mode and double tab space to start flying
- /tp ~ 512 ~
- Look down
