About this project
What does FTB Quests Optimizer add?
A lightweight mod-optimizer for FTB Quests. Removes micro-freezes when moving items and turning in quests, makes inventory checking smarter and quieter for the server - without changing the gameplay and quest rules.
Main features
- Smart inventory detection - heavy scans are launched only when really needed.
- Debounce checks - a series of events are added up to one delayed check (less load spikes).
- Ignore NBT noise - changes like charge/durability do not trigger unnecessary checks.
- Fast resource turn-in - item withdrawal in one pass and one progress update.
- Icon cache (client) - smoother quest book and tips.
Settings (snbt)
- detect.debounce - enable debounce.
- detect.delay_override — override check delay (tick), -1 = like in FTBQ.
- detect.ignore_nbt_only_changes — ignore "same item + quantity".
- consume.aggregate — aggregated resource delivery.
- consume.max_slots_per_pass — limit of scanned slots per pass.
Compatibility
- Does not change gameplay/progress, safe for current worlds.
- Works in singleplayer and on servers.
- Recommended on server (biggest effect). Client is optional for UI cache.
- NeoForge 1.21.1+, requires FTB Quests installed.
Why install?
- Less lag when managing inventory.
- More stable TPS on large bases.
- Smoother quest interface.
Just install the mod — it will do the rest itself.
If you want better performance, install my second mod, both mods will practically eliminate the lag problems associated with achievements and quests.
Feel free to write about all problems and suggestions on my github! Good luck!
