Why not C2ME?
Adrenaline takes a more aggressive approach to speeding up world generation. Instead of keeping Minecraft’s slower systems mostly unchanged, it replaces some of them with faster ones.
C2ME keeps more of Minecraft’s original world generation system, that can be less disruptive, but it may also reveal problems in Minecraft or other mods that were never designed to run that way, which is often why crashes happen.
