Improve Compatibility With Mods That Extend Resource Packs

Why Some Mods Cause Extra Lag

Certain mods extend or modify how Minecraft handles resource packs, adding extra processing steps during pack scanning. When combined with vanilla's blocking scan behavior, these mods can cause severe performance issues that make the Resource Pack screen nearly unusable.

How This Mod Helps

Async Pack Scan Mod isolates pack scanning to a background thread, which prevents heavy mods from blocking your game:

• Mods that add custom pack validation no longer freeze the interface
• Mods that process pack metadata work without causing stutters
• The Resource Pack screen remains responsive even with complex mod interactions
• You can use multiple resource pack–related mods together safely

What to Expect

With this mod installed alongside other pack-related mods:

• The Resource Pack screen opens faster
• Scrolling and organizing packs stays smooth
• No more mysterious lag spikes when interacting with packs
• Better overall stability when using mod-heavy setups

If you use mods that interact with resource packs, this mod is essential for maintaining a smooth experience.
