Title Block updates cause extreme lag spikes

Launcher Type Twitch Desktop App

Modpack Skyfactory 3

Modpack version 3.0.13

Have you modified the pack? No

Details of the issue Everytime a block update occurs, my game gets a lag spike, which is very anoying, especially when there is a water block being placed and multiple block updates occur.

It is something not only happens on skyfactory 3, but also on other modpacks and I'm not sure where it comes from. This also occurs with light updates.

Does anyone have any idea what it could be?

EDIT: Also installing optifine removes the lag, but yeah, it has some complications with the compatibility of some mods.
