ArchaicFix Mod 1.7.10 - Phosphor Lighting Engine Backport

If you play Minecraft 1.7.10, you know the pain. Jungles stutter. Caves with lots of light sources stutter. Even normal biomes can get lag spikes. ArchaicFix Mod fixes that by backporting the Phosphor lighting engine to 1.7.10, giving you the performance you should have had all along.

What ArchaicFix Does

ArchaicFix is essentially Phosphor for old Minecraft. It rewrites how the game handles lighting calculations, which is why 1.7.10 gets so choppy in certain situations. Instead of recalculating lighting on the fly when blocks change, ArchaicFix optimizes those calculations.

Key Features:

Eliminates the famous 1.7.10 client-side stuttering
Stops lag spikes in jungles and light-heavy biomes
Backports Phosphor’s optimized lighting engine
Includes fixes for other vanilla bugs

What You Need

ArchaicFix requires two things to run:

Minecraft Forge

UniMixins Mod

Both of these need to be installed before you add ArchaicFix to your mods folder.
