HoR Performance Optimizer is a Vintage Story mod by Panduhs. HoR Performance Optimizer reduces crafting recipe checks and speeds up repeated handbook openings on heavily modded Vintage Story servers.
Why this mod is worth installing
It is useful for players and server owners who notice crafting-grid stutter, slow handbook loading, or extra interface overhead in large modpacks.
What HoR Performance Optimizer adds
The mod builds shared reverse indexes for crafting ingredients and recipe outputs when the server starts. When a crafting-grid slot changes, it can discard recipes that cannot use the current ingredients instead of sending every recipe through the full matching routine.
This is especially helpful in modpacks with thousands of recipes or items used in many combinations. Recipes with wildcard ingredients remain supported through a separate fallback path, while normal shelf interaction and other gameplay behavior stay unchanged.
Handbook opening is optimized for the ordinary overview screen: repeated opens avoid rebuilding the entire interface, and an empty search can skip expensive text scans. Typed searches and direct item-detail navigation retain their normal handling.
The mod also addresses interface details around the optimized handbook path, including restoring the search field display and focus. Its purpose is targeted performance improvement rather than adding blocks, items, or new gameplay systems.
