Introduction

In vanilla Skyrim, movement feels very direct and responsive, but it often lacks a true sense of weight and momentum. Your character can instantly accelerate, stop, and change direction without any noticeable physical resistance.

This creates a subtle break in immersion. Carrying heavy armor, weapons, and loot should influence how you move, how quickly you can change direction, and how stable you feel in combat.

This mod introduces a fully engine-level weight based movement inertia system. Acceleration and deceleration are smoothly adjusted, and your current Carry Weight ratio dynamically affects responsiveness.

Heavier loadouts result in slower acceleration, stronger resistance when reversing direction, and more noticeable momentum. In addition, performing sharp turns will now apply a realistic slowdown effect. The heavier you are, the stronger this turn penalty becomes, making movement feel grounded and physically believable.

The goal is not to make movement clunky or frustrating, but to restore logical physics behavior while keeping controls smooth and responsive. The result is a more immersive and weight aware experience throughout Skyrim.

Mod Overview

This mod enhances player movement by introducing dynamic acceleration and deceleration based on carried weight.

Key features include:

  • []Weight based acceleration scaling

    []Adjusted deceleration behavior

    []Stronger resistance when reversing direction

    []Sharp turn slowdown that increases with higher carry weight

  • Fully configurable gameplay parameters

    All calculations are handled directly at the engine level for consistent and smooth behavior without scripts running in the background.

    Configuration

    The mod is fully configurable through the included INI fi
