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 youโ€™re looking for additional client features such as HUD enhancements or shader support, consider trying Onyx instead.

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.
