Siesta

Siesta - NPC Performance for Schedule I

> 🛟 Need help or found a bug? Get support at support.doodesch.de/siesta.

> Distant NPCs take a siesta so your FPS doesn't. Siesta puts off-screen, far-away NPCs to > sleep - hiding them and pausing their movement/schedule - then wakes them cleanly as you approach. > Works on every NPC in the world, including ones added by other mods.

Features

• Distance + visibility LOD for all NPCs. Off-screen NPCs beyond a configurable distance are hidden

(no render/animation cost); far, idle, non-essential ones also have their movement and schedule paused (the NavMeshAgent is the biggest per-NPC cost).

• Functionality-first. Dealers attending a deal, employees mid-task, customers in a deal, story/quest

NPCs, anyone in dialogue, in a vehicle, KO'd or near any player are never paused - only ever hidden.

• Clean wake-up. A woken NPC re-enables its schedule, catches up to the current in-game time, resumes

movement and repairs its NavMesh placement before it is shown again - no T-pose, no stuck agents.

• Multiplayer safe. Hiding is purely local per client; the movement/schedule pausing runs only on the

host who owns NPC simulation, so there is no desync.

• Cheap and self-tuning. A small, fixed number of NPCs is re-checked per frame, so the mod's own cost

stays flat regardless of how many NPCs exist.

Requirements

• Schedule I (IL2CPP) with MelonLoader 0.7.3+.
• S1API (pulled in as a dependency).

How much FPS will I gain?

The win scales with how many NPCs are far from you - it's biggest in NPC-dense saves (e.g. with NPC-adding mods) and small in sparse spots, because NPC simulation isn't always the dominant frame cost. Siesta only ever removes work for NPCs you aren't looking at, so it's a safe, free-when-idle optimization.
