Description
ArchaicFix implements a number of bugfixes and optimizations for Minecraft 1.7.10. Please see the README on GitHub for a more complete list, but here are a few highlights:
- Removes/reduces the infamous client-side stuttering in 1.7.10, particularly in biomes with many light updates like jungles
- Backport of the Phosphor lighting engine (the original repository is no longer available, this link leads to my 1.12 fork which is the closest to the original, and still has the original branch)
- Many other fixes for various vanilla issues
Additionally, ArchaicFix patches a few common annoyances in other mods.
Newer versions of ArchaicFix require a GTNHMixins-compatible mixin loader like UniMixins to be installed.
