About
OptiFine brings a collection of OptiFine-like features to NeoForge, aiming to improve performance and provide a modular alternative to using OptiFine itself. Its visual features include HD textures and resource-pack support, connected textures, capes and custom models, dynamic lighting, shader compatibility, block and entity model enhancements, and smoother animations; it also includes a configurable zoom function. The pack is intended to reduce stuttering and improve frame rates, including on lower-end systems, and is described as compatible with additional mods for custom setups.

Security
No harmful code found in its projects
We checked all 54 projects 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 projects54 projects
- Files in the pack itself1 settings file, 80 other files, 80 mod jars.
- 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.

4 mods send something about you
We read the code of all 53 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
- Crash reports or usage dataTheir author declares crash reports or usage data on Modrinth, or such a service is named in their files. Reading their code did not show it.1 mod
- Send nothingTheir code contacts no web address.47 mods
AI
AI used in 3 of the 53 mods we checked
We found an AI tool in them, or their authors declared AI content.
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.
