About
Speed Of Light is a lightweight, client-side modpack designed to improve Minecraft performance and reduce lag while allowing you to use shaders, without substantially changing vanilla gameplay. Its optimizations target entity and block culling, lighting calculations, asset loading, memory use, networking, and core systems such as physics, mob AI, and block ticking. The pack includes BSL and Complementary shader options, including Complementary Reimagined, and uses Iris for shader support. Video settings start at their lowest values for performance, so you can raise them to suit your preferences once in game.

No harmful code found in its projects
We checked all 28 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 projects28 projects
- Files in the pack itself33 settings files, 2 other files, 2 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.

2 mods send something about you
We read the code of all 24 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.1 mod
- Send nothingTheir code contacts no web address.21 mods
AI
AI used in 2 of the 24 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.
- Description and changelogsThe description, project page and newest changelogs: sentences saying an AI tool was used, and text pasted from an AI chat.Nothing found1 of 39 changelogs read
