In vanilla Minecraft, the game regularly scans all resource pack sources to refresh the resource pack list. While this is usually harmless, the scan is performed very frequently in the Resource Pack Organizer screen, which can cause serious performance issues when many resource packs or certain mods are used. Async Pack Scan Mod improves the situation by running the resource pack scan in the background instead of blocking the game, resulting in a much smoother user experience.
Features:
- Background resource pack scanning
- The game no longer freezes while checking resource packs
- Scanning is done on a separate thread
- Smoother Resource Pack screen
- Reduces lag spikes when opening or resizing the menu
- Keeps the interface responsive even with many packs installed
- Better compatibility with other mods
- Prevents heavy slowdowns caused by mods that extend resource pack processing
- Vanilla-friendly behavior
- Does not change how resource packs work
- Only optimizes
