FAQ
Does this change any gameplay?
No. Every mod here is strictly performance improvements and bug fixes. No enemies, moons, items, or mechanics are added or changed.
Is this compatible with other modpacks?
Yes. AurelionPack Performance is designed to be a drop-in layer. If another modpack includes any of the same mods, your mod manager will handle the deduplication.
