Description

It is a simple mod that makes powered/activator rails turn on/off up to 4x faster. The best working condition is that you feel nothing when it is operating but smooth and fast rail updates.

Before you download

Please allow me to convey my sincere gratitude towards FX Morin for his code! Most of the code are written by FX Morin and I just do some little adjustment to make it operating.

What's new

An update of FX's RailOptimization for 1.16-1.21.x fabric.
Fix the severe crash when loading the mod.
Lighter code implementation by removing architectury API.

Known issue

Incompatible with any version of Carpet TIS Addition(CTA).

Reason

Method used to optimize the rail's performance is conflicted with CTA's update mechanism. CTA uses various methods to edit or avoid updates including rail's update(e.g. railDupingFix). Method conflicts will cause some unpredictable failure when injecting mixin and it's truly appeared.
