Optimizing Performance in Fallout 4: A Technical Guide

Introduction

Fallout 4, while an incredible open-world RPG, is notorious for performance issues, including frame drops, stuttering, and long load times. Whether you’re on PC or console, optimizing the game can vastly improve your experience. This guide provides a structured troubleshooting approach to enhance performance, covering FPS boosts, stutter fixes, mod recommendations, and hardware tweaks.

General Optimization Tips

PC Performance Tweaks

3. Optimize Graphics Settings

Lower settings for a balanced performance/quality ratio:
- Textures: High
- Shadows: Medium or Low
- God Rays: Off or Low
- Ambient Occlusion: SSAO or Off
- Anti-Aliasing: TAA (better performance) instead of FXAA

4. Disable V-Sync & FPS Cap

Fallout 4 locks FPS to 60 by default, which may cause stuttering.
Disable V-Sync:
1. Navigate to Documents/My Games/Fallout4.
2. Open Fallout4Prefs.ini.
3. Locate iPresentInterval=1 and set it to 0.

5. Enable High-Performance Mode

Windows Performance Settings:
- Go to Control Panel > Power Options and set to “High Performance.”
NVIDIA Control Panel:
1. Open NVIDIA Control Panel.
2. Go to “Manage 3D Settings.”
3. Find Fallout 4 and set “Power Management Mode” to “Prefer Maximum Performance.”

6. Fix Stuttering & Micro-Freezes

Change CPU Priority:
1. Open Task Manager (Ctrl + Shift + Esc).
2. Find Fallout 4 under “Processes.”
3. Right-click > “Go to Details.”
4. Right-click Fallout4.exe > Set Priority > “High.”
Disable Mouse Acceleration:
1. Open Fallout4.ini (Documents/My Games/Fallout4).
2. Add/change:[Controls] bMouseAcceleration=0

7. Install Performance Mods

Essential Performance Mods:

BethINI (Improves INI settings for optimization)
Unofficial Fallout 4 Patch (Bug fixes and performance enhancements)
High FPS Physics Fix (Prevents physics issues when unlocking FPS)
Optimized Vanilla Textures (Better texture compression for performance boost)
Insignificant Object Remover (Removes clutter that impacts FPS)

How to Install Mods:

Use Mod Organizer 2 or Vortex for mod management.

8. Clear Cache & Reinstall

Clear Console Cache:
- Turn off the console completely.
- Unplug it for 5 minutes.
- Restart and relaunch Fallout 4.
Reinstall the Game:
- Delete and reinstall Fallout 4 to remove corrupted data.

9. Manage Save Files

Large save files slow performance.
Delete old saves or use a fresh start for better stability.

10. Reduce Load on the System

Close background apps (Spotify, YouTube, Twitch).
Enable Performance Mode on Xbox/PS5.

11. Adjust In-Game Settings

Reduce Draw Distance and Shadows.
Lower Lighting Quality for a smoother experience.

Hardware Upgrades & Advanced Tweaks

12. Upgrade Your Hardware

RAM: Fallout 4 benefits from 16GB RAM or more.
SSD: Switch from HDD to SSD for faster load times.
GPU: Upgrade to at least GTX 1660 Super or Radeon RX 5700 XT for high performance.

13. Use NVIDIA DLSS or AMD FSR (PC Only)

Install NVIDIA DLSS mod or use AMD FSR for better performance.

14. Overclocking (Advanced Users Only)

Use MSI Afterburner to overclock your GPU (small increments for stability).
Overclock CPU cautiously using BIOS settings.
