Peak Performance is a lightweight, minimal system to handle Hunger, Thirst, and Exhaustion.

• Fully open-source.
• Minimal to zero script overhead in gameplay.
• Intuitive Tension system inspired by Focus from Last Seed.
• Tracks how well Needs are maintained over time. Pending
• Simple but immersive Intoxication system.
• Lightweight Cleanliness system.
• Immersive and vanilla-friendly Sleep Quality system.
• Optional Auto-Consumption system.
  

All systems are built from scratch for performance and immersion.
There are four core systems; Hunger, Thirst, Rest, and Intoxication - and an optional Cleanliness system.

Generally, the system will function exactly as you'd expect.
Simply eat, drink, and sleep when prompted and you will find yourself doing just fine.
A list of all Needs and their conditions and progression is below.

Since 1.0 the system runs on a timer that checks progression frequently.
Waiting or fast traveling will now incur the expected Needs advancement.
Sleeping still 'pauses' needs for practical purposes - this is intentional.

Hunger System

Hunger has four stages - Satiated, Full, Hungry, and Starving.
Hunger will progress stages every 8 hours UT.
There are three types of food - Filling, Normal, and Poor.
Each one restores varying amounts of Hunger - between one and three stages' worth.

Hunger primarily controls Health Regeneration Speed.

Thirst System

Thirst's stages are Refreshed, Hydrated, Thirsty, and Dehydrated.
Thirst will progress stages every ~5 hours UT.
Drinking any normal drink will restore three stages.
Alcohol may increase Thirst or simply restore less than water or other beverages.

Thirst primarily controls O2 Recovery Speed.

Exhaustion System

Exhaustion's stages are Rested, Awake, Tired, and Exhausted.
Exhaustion will progress every ~14 hours UT.

Exhaustion primarily controls Experience Gain.

Sleep is the cornerstone of the mod and conditions are more restrictive to gain the Rested status.
You must sleep at least 8 hours in a safe location to awaken Refreshed.

Tension System

If you are not in a safe location when Needs Evaluation begins, your needs will be 'queued' and are stored for later.
The next time Needs Evaluation runs in a safe location you will incur the entire amount of 'stored' needs.
Please evaluate your conditions and resources carefully when exploring dangerous locations.

Hygiene System

When enabled, your Persuasion and Stealth are slightly affected by whether you are Bathed or Dirty.
Cleanliness progresses or advances depending on your location - in settlements or on your ship, it will generally not diminish.
A usable Shower can be constructed on your ship or in outposts that will confer the Bathed status.
Craftable Sani-wipes will also confer Bathed.

Secondary Systems

Stimulants
Stimulants are sorted into two categories - Strong and Weak.
Weak Stimulants are things like coffee or some tea blends. Strong Stimulants are generally amphetamines or their derivatives.
Consuming Stimulants will instantly lower your Exhaustion by a moderate amount, while increasing your Sleep Debt by the same amount.

Alcohol/Intoxication
Each time you consume Alcohol, your Intoxication increases by a certain amount.
This amount varies depending on skills, Vitality, and the type of drink consumed.
Intoxication decays over time and has unique effects like steadiness with weapons.

Alien DNA
Spacefarers with Alien DNA are generally compatible with Alien-derived foods but not with normal Human foods.
Incompatible foods will be chosen less preferentially for auto-consume and will restore less Hunger when eaten.
Incompatibility can be overcome by choosing certain Backgrounds or gaining certain Skill Ranks.

Cooldowns
Consuming food or drink in rapid succession will have limited effect.
The "Recent" status effect in the menu will display any active cooldowns.

Auto-Consumption System
This system must be toggled on from Gameplay Options.
If it is enabled, you will automatically eat or drink to meet your Needs once reaching the final stage.
This may consume food or drink items that you would prefer to keep, so use it with caution.



In theory, Peak Performance is compatible with anything except other Needs mods.

Do not use with vanilla Sustenance system or any mods that utilize it.
They will be incompatible at worst, and simply annoying to use together at best.
Ensure that the Gameplay Option for Sustenance is set to Disabled.

The Well Rested perk is 'silenced' via a change to the record.
If this is reverted by another mod, gameplay will be unaffected but there may be message spam on wakeup.

Food and Drink Detection

This is done via vanilla keywords. Any mod-added foods or drinks that are correctly tagged should work.
Vanilla records are not touched in any way.
Mods like Good Food are generally compatible.

Alcohol or Curative Detection

These are done via formlists. Patching will generally be required for mod-added alcohol or chems.
Mods that alter any vanilla ingestible records are generally compatible.



Simply install with your mod manager of choice.
The mod will initialize the next time you wake up from sleep.



On Progression
As of 1.0, progression now takes place according to hours UT.
This has some downsides in certain scenarios but is generally more stable than the previous implementation that ran on real-time timers.



Bethesda for Starfield and the Creation Kit.
The Tension and Vitality mechanics are shamelessly borrowed from Last Seed originally by Chesko and continued by Aytrus.
This mod is nowhere as complex or multi-faceted but I hope I've managed to capture some of its gameplay depth.

The Vim and Vigor concepts in general which compose Vitality are lifted from Vim and Vigor Advanced for Oblivion by Ssenkrad.
