A modpack that helps your game run more smoothly.
Modpacks get no grade of their own, so we show the grades of its mods. Of its 35 graded mods, 34 are graded A or B, 1 C and none D to F. Its last update came out 9 months ago, for Minecraft 1.21.11. See the mods
[Ck7] Pack de Optimización is a performance-focused Minecraft pack designed to improve frame rates and smooth gameplay, particularly for players building large projects or using shaders. It combines Sodium and Sodium Extra for rendering performance and graphics options, Lithium for physics and AI optimizations, Dynamic FPS to reduce resource use when the game is in the background, and FerriteCore to lower memory usage. For visual features, the pack includes Iris for shaders and LambDynamicLight for dynamic lighting, with Indium providing compatibility for custom block and entity rendering alongside Sodium. Other rendering optimizations include Entity Culling, ImmediatelyFast, Entity Model Features, Entity Texture Features, Enhanced Block Entities, Model Gap Fix, and Modern Fix, covering visibility, entity rendering, block entities, connected models, compatibility, and performance. Better F3 provides a more detailed, cleaner debug screen.
Written from CurseForge . How we write it
The mods of its newest release (Minecraft 1.21.11 · Fabric, 2 Feb 2026). Each check result is for the latest files of that mod, which may not be the version in this pack.
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.
3 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.
No sign that AI was used to make its mods
We found no AI use from before this release (2 Feb 2026) in the 37 mods we checked.
4 mods show AI use only from after it, so it does not apply to the versions in this pack.
Made with AI: not checked yet
We have not looked for AI tools in the pack itself 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.
