DefCore Optimization Modpack
DefCore Optimization Modpack - this is a optimization fabric modpack based on sodium. It adds optimization of different areas of the game. Render optimization, RAM optimization, fix of some errors, changing the light rendering, etc.
The modpack is based on sodium, and about a quarter of mods depend on it or are recommended for sharing. Why not optifine? Because the optifine is outdated and sodium copes with optimization much better (when using additional mods)

Optifine features
This modpack allows you to use most of the optifine features, such as shaders, approximation, custom 3d renaming models.

Why this modpack and not others?
General Optimization
This modpack is ideally optimized for both weak and powerful PCs. It shows good AND MOST IMPORTANTLY stable performance, compared to other optimized modpack
Saving time
Also, this modpack is extremely convenient to use due to the removal of some loading screens. This allows you to save time and not be distracted by the download screens.
FPS stabilization
Fps is stable when loading fragments and does not jump due to the c2m mod, also due to more culling and entity culling, you can make large farms and at the same time not feel lags, hiding mobs behind buildings.
Сompatibility
Also, this modpack will work on all servers or single worlds, as it does not introduce new content, but only optimizes and improves the gameplay
Based on fabric
Fabric is a more optimized core than forge. Mods for it come out faster and are updated regularly and has excellent support for mods.
DefCore Optimization 설치 방법
With Millida Launcher
Install Millida Launcher
The launcher is free: download it at millida.net/launcher and sign in with any nickname.
Click “Install” on this page
The launcher opens and installs the modpack for Minecraft 1.21.1–1.21.10 on Fabric automatically.
Launch the game
A profile with it appears in the launcher: click “Play”.
Manually
Download the modpack archive
In the version list above, pick the file DefCore Optimization 1.21.10 0.9.1.mrpack (295 KB).
Import it into a launcher
A launcher that supports modpacks (Millida Launcher, Prism) takes the archive via “Add modpack”, then “From file”. No need to unpack it yourself.
Allocate memory
Modpacks need more memory than the plain game: set 4–6 GB in the profile settings.
Minecraft 1.21.10 runs on Java 21: with a different Java version the game may close right after launch.
