About
Xavier Optimized is a client-side Minecraft modpack built to improve frame rate and game-tick performance while preserving vanilla survival mechanics, rather than changing how the game is played. Its optimization core includes performance mods such as Sodium, Lithium, More Culling, ImmediatelyFast, FerriteCore, Entity Culling, and Dynamic FPS, with related tools for memory, rendering, and network efficiency. The pack also adds practical client features, including AppleSkin hunger information, chat heads and extra chat history, mouse tweaks, dynamic crosshairs, and Bobby for server chunk caching; e4mc provides a way to share a world with friends over the internet. Depending on the pack edition, it includes visual options such as Iris Shaders or Oculus, dynamic lights, and configuration menus for graphics settings. The pack is designed for single-player and multiplayer use, runs on the client, and can connect to servers that accept vanilla clients; its included mod selection varies by edition.

Security
No harmful code found in its mods
We checked all 37 mods and the files in the pack itself, without running them.
Why we show this: a modpack installs the files of its mods, and each mod runs on your computer like any program. Our checks look for known signs of harm. They cannot prove that a file is harmless. In the grade: a modpack has no grade of its own, and each mod's result counts in that mod's grade.
How we checked
- Its projects37 mods
- Files in the pack itself53 settings files, 1 mod jar.
- Author on ModrinthThe disclosure form on Modrinth, where the author declares that the project reads or edits things on your system outside the game. Since 13 Aug 2026, Modrinth's rules require it when this applies.Nothing declared about your system outside the game.
Privacy
5 mods send something about you
We read the code of all 37 of its mods, without running it.
Why we show this: a modpack runs the code of its mods, and a mod can send things about you over the internet, like your player name or your login. Contacting an address to check for updates or download files sends nothing about you. Not in the grade: sending data can be normal for what a mod does.
How we checked
- Go online onlyTheir code contacts a web address, for example to check for updates. We found nothing it sends about you.2 mods
- Send nothingTheir code contacts no web address.30 mods
AI
No sign that AI was used to make its mods
We found no AI use from before this release (22 Feb 2026) in the 37 mods we checked.
3 mods show AI use only from after it, so it does not apply to the versions in this pack.
No sign so far that AI was used to make the pack itself
We looked for AI tools in its texts and found none.
We have not read its files and images yet.
Why we show this: some players and servers avoid projects made with AI, and AI in the game can send what you write to an online service. Not in the grade: using AI does not tell whether a project works well or is kept up to date.
How we checked
- Author on ModrinthThe disclosure form on Modrinth. Since 13 Aug 2026, Modrinth's rules require it when a substantial part of the code is AI output, when an asset is mainly AI output, or when the project or its page relies on generative AI.No AI content declared.
