DEPENDS ON MODERNFIX! (and Space-BossTools)
A performance mod for Space-BossTools, and "optimizes" a lot of its absolutely terrible code.
On its own with Space-BossTools, ModernFix, and Embeddium, this mod can save around 20% on both the server and client, especially when you're actively on a planet/in orbit.
However, when put into a larger modpack (for example, FTB Integration by Parts DX), it can still save up to 9% (even more, depending on how many entities are loaded), still on both sides.
The aims of this mod are to improve performance while using Space-BossTools, while still keeping the same features and being easily configurable.
