About
C2ME OpenCL Acceleration Module extends C2ME by using OpenCL-capable hardware to accelerate Minecraft world generation. It currently offloads the noise and biome generation stages, aiming to preserve vanilla world-generation behavior while improving chunk generation speed; the stated performance gain of 80% or more applies to CPU-bound vanilla Overworld generation and can vary with seeds and datapacks. It is designed to work with vanilla-compatible world-generation datapacks, including Terralith, Incedium, Tectonic, and CliffTree, while mods using custom density functions or entirely custom world generators may not work; Biomes O’ Plenty, TerraBlender, and Biolith are specifically reported to disrupt biome placement. The module can run in singleplayer or on dedicated servers, and by default schedules work across the available OpenCL devices, with configuration options to whitelist or blacklist devices.
Written from Modrinth . How we write it
In-game changes
Changes the game's code in 5 areas: Chunk loading and storageChanges 3 game code files in this area: how the game loads, tracks, saves and unloads chunks., World generationChanges 2 game code files in this area: terrain, biomes and structures made when new land is created., User interfaceChanges 1 game code file in this area: menus, screens, tooltips, the chat window and the in-game overlay., Server and world logicChanges 1 game code file in this area: the world, commands, scoreboards, saved data and game rules. and Rendering and graphicsChanges 1 game code file in this area: drawing mobs, items, particles and textures on screen..
A library packed inside it changes 7 more game code files: Concurrent Chunk Management Engine (Optimizations/Acceleration/OpenCL).
Adds no new blocks, items or other content.
Keeps all of vanilla Minecraft's textures, models and sounds.

Security
No harmful code found
We checked its files and read their code, without running it.
What it can do on your computer
- Connects to the internet
- It has code that can go online, for example to check for updates, load skins or send crash reports. Found in commons-compress, a library it includes and in lwjgl-3.4.1-unsafe, a library it includes. See Privacy
- Can update itself
- It can add or replace files in your mods folder, for example to update itself. Only in its files for NeoForge 1.21.1 to 26.2.
- Creates settings files
- The mod keeps its settings in the config folder of your game, where you can change or delete them. Only in its files for NeoForge 1.21.1 to 26.2.
Why we show this: a mod runs on your computer like any program, so harmful code in it can take your accounts or files. Our checks look for known signs of harm. They cannot prove that a file is harmless. In the grade: malware means no grade, and a Warning in a latest file for a recent Minecraft version lowers it.
How we checked
- FilesWe download the files from Modrinth or CurseForge and look at what is inside them and what their code can do, without running them. Fixed rules tell what is harmful.7 latest files: the newest file for each Minecraft version and loader. All 7 are for recent versions. Recent versions: those released in the last 2 years, plus 1.20.1 and 1.21.1, among the most played in modpacks. See each file in Releases
- Their codeWe turn the code of the files back into readable code and follow what it does, without running it. This shows what it downloads, what it sends and where your login goes.Read without running it
- 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.
- Looked for, not foundWe looked for these in the file and did not find them.Folders outside the game, other programs, the webcam or microphone, an AI service.
Privacy
We found nothing it sends
We read its code without running it: it contacts no web address while you play.
Why we show this: 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
- Files readWe read the code without running it. We list each web address the code contacts while you play, and what it sends. Code that is never used is left out.The code of all 7 files, for recent Minecraft versions. See each file in Releases
- Author on ModrinthThe disclosure form on Modrinth, where the author declares crash reports, usage data and advertisements. Since 13 Aug 2026, Modrinth's rules require it when a project collects data on its users or shows advertisements.Nothing declared about crash reports, usage data or advertisements.
AI
No sign that AI was used to make it
We looked for AI tools in its texts, files, images and code history and found none.
No sign of AI in the game
We found no AI service, AI library or AI model file in its code.
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 or AI features declared.
- Code historyThe public code on GitHub: who made each change, credit lines such as "Co-authored-by", and its files.Nothing found
- Description and changelogsThe description, project page and newest changelogs: sentences saying an AI tool was used, and text pasted from an AI chat.Nothing found20 changelogs read
- Its filesFiles that AI coding tools leave behind (like AGENTS.md), and the texts inside the files you download.Nothing found
- Images in its filesHidden data in the images of the files you download, where AI image tools write their name and settings.Nothing found
- Code of the modThe code and files of the mod, read without running it: addresses of AI services, AI libraries, AI model files and a place for your own AI key.No AI service, AI library or AI model file207 code files read
