!THIS IS NOT OFFICIAL PORT OF OPTIFINE!

This is a resource pack for Minecraft Pocket Edition or Bedrock edition, this will help your performance 2-5%, i know its not that big but what did you expect from a texture pack?

And no there's no additional features like shader, dynamic light, fps display, or other. There's also a fps display texture pack but i tested it but its not accurate so i cant add any of those feature

So what is the differences between Fastest - Fast - Fancy

Fastest:
Optimize texture by removing animation/flipbook, low fire, and optimizing water and block this also remove some particle to help you remove lag

Fast:
Only optimize texture and remove particle this will help you a little

Fancy:
Remove particle only.

When is it going to get updates? I will only update when 1.21 is realesed
