How to optimize this minecraft from HritikRC's channel?

The file is this:

v3 mod 1 v3.zip (4.2 MB)

And this file runs slowly, instead giving they the paramenter ‘render distance’ 100 blocks of value, but when I give 40 blocks for render distance value it runs good, but is less than original parameter of minecraft makes it lag, the same giving more than 1 of chunkSize. It haves a solution? Thanks anyway and sorry any convenience…
