As of version 5+, this mod is now explicitly incompatible with VanillaFix and TexFix as their functionalities have been improved upon and added to the mod.
1. Optimize RAM usage. Here's what happens when you add it to a large modpack (without Foamfix):
2. Fixes crashes, within different mods, and Forge itself.
3. Optimizes code in general.
As of 2.3, requires MixinBooter.
Recommend using VintageFix along with this.
