About the Aestpack modpack
How often does minecraft lag for you? And if you add a few mods to improve the graphics?
I got tired of this problem and decided to make my own assembly that includes a sufficient number of mods to improve the visuals, as well as optimization. I selected mods so that nothing conflicted.
OptiFine Parity
Supports most OptiFine features, including shaders and texture set support.
Performance
I just tried to make a carefully selected mod pack so that none of the mods conflict and give a good fps boost.
Vanilla
This modpack does not change the standard of minecraft, so you can play the usual vanilla without unnecessary things.
Works everywhere
AestPack works both in single and local worlds, and on any servers.
Updates
We try to update the build regularly, which is useful for many people who like to upgrade to each new version.
Complement
You can use the modpack as a base for your main build with other mods.
Open Development
AestPack is open source, as are most of its mods. We welcome user suggestions and collaborate with mod developers.
AestPack collected a lot of cool mods, resource packs and shaders.
We made a pack that not only optimizes Minecraft and adds FPS, but also improved the visuals without losing frames. Our modpack was created for those who really want to immerse themselves in the world of Minecraft and improve its performance!

Modpacks need more memory than the plain game: set 4–6 GB in the profile settings.
