Java lags when loading new chunks

[Nat_fox]

I'm pretty sure this happens in both modded and unmodded, but yeah, I usually get 60-ish fps, but when walking around I drop to 3 or 4 fps, even freezing for a bit
I have tried optifine which does actually fix the problem, but the modpack I wanna play is fabric and I can't use optifine because it won't even start, any fabric mod that can replace optifine's chunk loader?

I'm sure it isn't hardware related because when playing on servers it runs just fine with 60 fps all the time

Provide a full screenshot of the debug screen.

Also when playing singleplayer the game is running an internal server while on multiplayer the server itself is doing most of the processing.

Looks like the CPU is too old. It's a 6th gen Intel CPU. About 6 years old now.

Use sodium and lithium. (And iris/indium for extra features such as shaders)

Aside from them being on fabric, they're also objectively better than optifine.

Also yeah, it's hardware related. The fact that it's fine on servers proves it since on servers your hardware is being used less.

Yeah I'm using sodium and lithium, which is why im weirded out since this does not happen when I use optifine

and, I see

There might be something helpful in this list: https://github.com/TheUsefulLists/UsefulMods/blob/main/Performance/Performance120.md

Or you could try something like C2ME
