I believe that your mod fixed the chunk-crossing gigantic lagspike issue for me and for a lot of people
Its amazing! So please update it

Smooth Boot is no longer needed in 1.20 See https://modrinth.com/mod/smoothboot-fabric

Wrong, Mojang only fixed Minecraft start up time issue, but not Minecraft CPU bottleneck and chunk generation, loading, which smooth boot fixes i believe by thread priority management (sorry if i'm wrong), here are some screenshots:
Without Smooth Boot (1.19.4)

With Smooth Boot (1.19.4)

It also fixes chunk generation stutter in 1.20.1 as well if i change version support in config file:
With smooth boot (1.20.1)

Without smooth boot (1.20.1)

How can you run smooth boot in 1.20.1? You said to change the supported version in the config file, how do you do that?

@PedroLVA You download the latest smooth boot mod version, than open it with archiver like 7zip, and edit fabric.mod.json file

than add this ">=" next to 1.19.4 in this field

will look like this

than save it in archive, and add mod to your mods folder

@Kennybust Thank you so much, you're a life saver!

@Kennybust you can also use fabric dependency overrides if you don't want to edit the mod's files.

There's an updated fork now to port the thread priority changes.

My two cents, with/without

I made a version 1.20 that only changed the version

Thought I might chip in here, @getchoo and I have forked the mod and published it to Modrinth and will be maintaining it for future versions (with the creator's permission of course) Feel free to check it out!
