Async Pack Scan Mod FAQ
10 questions players actually ask, answered.
Do I need to configure anything after installing this mod?
No, Async Pack Scan Mod works automatically once installed—resource pack scanning runs in the background without any setup required. You'll notice the improvement immediately when opening the Resource Pack screen.
Why does my resource pack list sometimes take a moment to update?
The mod scans packs asynchronously in the background, so the list updates after a short delay rather than freezing the screen instantly. This trade-off keeps your game responsive while the scan completes.
Will this mod work with mods that add custom resource pack features?
Yes, this mod is designed to improve compatibility with mods that extend resource pack processing by preventing those heavy operations from blocking the main thread. You should see better performance even with complex resource pack mods installed.
Can I use this mod with hundreds of resource packs?
Yes, that's one of the main benefits—the mod handles large numbers of packs much better than vanilla by scanning them on a separate thread, preventing the severe lag spikes you'd normally experience.
Does this mod change how resource packs load or function?
No, the mod only changes *when* and *how* the scanning happens—the actual resource packs load and work exactly as they do in vanilla Minecraft.
What should I do if the resource pack list feels out of sync after adding new packs?
Wait a few seconds for the background scan to complete, or try closing and reopening the Resource Pack screen to trigger a fresh scan. The list will update once the async scan finishes.
Does this mod reduce FPS or cause other performance problems?
No, the mod actually improves performance by preventing the main game thread from freezing during pack scans. The background scanning uses minimal resources and should not negatively impact your FPS.
Will this mod work on servers or only single-player?
This mod only affects the client-side Resource Pack screen, so it works in both single-player and multiplayer without requiring the server to have it installed.
Can I disable the async scanning if I prefer the vanilla behavior?
The mod doesn't include a toggle option—it's designed to always run asynchronously. If you need vanilla behavior, you would need to remove the mod.
Why does resizing the Resource Pack window sometimes cause lag even with this mod?
Resizing can trigger a new scan, but the mod ensures this scan happens in the background instead of freezing the screen. If you still experience lag, it may be caused by an incompatible mod or an extremely large number of packs.
