About this project
What does LightSpeedRe - Launch optimizations add?
This is a high-version (1.20.1+) port of the Lightspeed mod.
It removes the model-baking optimizations that were already implemented in vanilla Minecraft 1.20.1, keeping only the resource-pack cache feature, which speeds up launch times.
(Currently, only ports for Forge 1.20.1 and NeoForge 1.21.1 are planned.)
Since version 1.2.0+, this mod introduces high-concurrency loading to improve startup speed. If you encounter any issues while using this mod, please try disabling the related option in the configuration file.
