Opal

Minecraft 版本： 26.2

平台： fabric

标签： lightweight multiplayer optimization

Opal is a lightweight Fabric client modpack designed to improve Minecraft performance, stability, and responsiveness while preserving the vanilla experience.

Designed for low-end systems, laptops, Chromebooks, and battery-limited devices, Opal prioritises optimisation without adding gameplay changes or unnecessary features.

If you’re looking for additional client features such as HUD enhancements or shader support, consider trying Onyx instead.

Notes
━━━━━━━━━━━━━━━━━━━━━━━━

• Client-side only
• Works on vanilla and modded servers (where client mods are allowed)
• Resource packs and settings included are optional and can be changed freely
• Support for older versions will take longer to release as newer versions take priority

Opal is intended to be a simple, dependable optimisation base that you can use as-is or build on with additional mods. Backup your worlds and configs when updating. This modpack is geared towards very low-end devices and therefore I will be very selective about the mods added to keep the total amount small and easy to run.
