VintageFix

Note: This mod requires MixinBooter to be installed to work, otherwise the game will crash on launch.

VintageFix is an optimization mod for Minecraft 1.12.2 that provides significant memory usage benefits and reduces load time a bit as well. This is accomplished by incorporating modified versions of FerriteCore's blockstate/model optimizations as well as a more up-to-date and reliable version of the old VanillaFix dynamic resources patch, which loads models on the fly instead of at game startup. There are also other bespoke optimizations included.

For best results:

• Do not use OptiFine. Use of OptiFine may cause rendering glitches and will also increase launch time.
• FoamFix must not be installed, as VintageFix fully replaces it (with more effective optimizations).

Additionally, note that VintageFix is still in its infancy and you may encounter some bugs/crashes. These should not cause any permanent damage to your game. If you do encounter issues, be sure to report them on GitHub.
