How To Fix 100% CPU Usage in Battlefield 6

Is your AMD CPU maxing out at 100% usage, causing stutter and lag in Battlefield™ 6? Learn how a simple automated PowerShell script creates a custom user.cfg file to optimize CPU thread management and drastically improve your in-game performance. [5800X, 7700X, 7800X3D]

How To Stop the Stutter & Fix 100% CPU Usage in Battlefield™ 6

Why Your CPU Is Struggling in Battlefield 6

Battlefield™ 6, built on the powerful Frostbite engine, is notorious for pushing PC hardware to its limits. One of the most common and frustrating issues PC gamers face, especially those with AMD Ryzen CPUs, is the processor constantly hitting 100% usage.

This happens because the game’s engine, by default, can sometimes mismanage how it distributes tasks across your CPU’s available cores and threads. When the CPU is perpetually maxed out, it leads to:

• Severe stuttering and inconsistent frame times.
• Reduced GPU utilization (bottlenecking).
• Higher CPU temperatures.

Fortunately, there is a tried-and-true community fix involving a custom user.cfg file that manually tells the game exactly how to utilize your physical cores and logical processors. This guide provides a simple, automated solution—a PowerShell script—to implement this fix instantly.

The Automated Solution: A Simple PowerShell Script

Creating and manually tweaking the user.cfg file can be confusing. One wrong number or a typo in the command can cause more issues. This automated script simplifies the entire process, making the performance fix accessible to everyone.

What Does the Automated Script Do?

This automated PowerShell script handles the entire configuration for you, ensuring the settings are applied correctly and conflict-free.

The Critical user.cfg Commands

The script generates a file with these essential lines, substituting ‘X’ (Physical Cores) and ‘Y’ (Logical Processors/Threads) with the numbers you provide:

Thread.ProcessorCount X
Thread.MaxProcessorCount X
Thread.MinFreeProcessorCount X
Thread.JobThreadPriority 0
Thread.MaxWorkerThreadCount Y

Example for a Ryzen 7 5700X (8 Cores / 16 Threads):

• Thread.ProcessorCount 8
• Thread.MaxWorkerThreadCount 16

Step-by-Step Installation Guide (One Command)

Follow these steps exactly to run the automated fix.

Step 1: Check Your Core and Thread Count

Before running the script, you must know your CPU’s specifications.

1. Open Task Manager: Right-click the Start button and select Task Manager.
2. Go to the Performance tab and click on CPU.
3. Note down the values for Cores (Physical Cores) and Logical processors (Threads).

Crucial Note for AMD Users: For this fix, the script specifically asks for your PHYSICAL CORE COUNT. The logical processor count (threads) is typically double this number.

Step 2: Open PowerShell as Administrator

1. Right-click your Start button (Windows icon).
2. Select “Terminal (Admin)” or “Windows PowerShell (Admin)” from the menu.
3. Click Yes on the User Account Control prompt.

Step 3: Paste and Run the Script

The script is hosted on GitHub for transparency and reliability: https://github.com/karimHI/BF6-config

Copy and paste this single command into the Administrator PowerShell window and press Enter:

iwr https://raw.githubusercontent.com/karimHI/BF6-config/refs/heads/main/Battlefield%206.ps1 | iex

Step 4: Enter Your Core Count

1. The script will prompt you to enter the number of PHYSICAL cores for your CPU (e.g., 8 for a Ryzen 7).
2. Type the number and press Enter.

The script will now automatically locate your Battlefield™ 6 folder, apply the thread optimization, and create a fresh user.cfg file.

Important Cautions Before You Run

• Existing user.cfg Deletion: This script is designed to automatically delete your existing user.cfg file. This is necessary to ensure a clean, conflict-free application of the new thread settings. Any other custom settings you had in that file (like custom keybinds or graphic tweaks) will be removed.
• Intel CPUs: This specific core-limiting tweak is primarily intended for AMD Ryzen CPUs where SMT (Simultaneous Multi-Threading) contention is a common issue with the Frostbite engine. Use caution on modern Intel CPUs with E-cores (Efficiency Cores), as incorrectly limiting the thread count can sometimes harm performance and 1% Lows.

How to Confirm the Fix Worked

After running the script and launching Battlefield™ 6:

1. Monitor Your CPU Usage: Use Task Manager or an overlay (like MSI Afterburner/RivaTuner) while playing a high-action multiplayer match.
2. Look for the Drop: You should see your average CPU utilization drop from the 90-100% range to a much healthier 40-70% range, depending on your specific hardware.
3. Check for Smoothness: The most important result is a noticeable reduction in stuttering and more stable, consistent frame pacing.

If the fix did not work or caused new issues, simply navigate to your Battlefield™ 6 installation folder and delete the user.cfg file to revert to the default settings.

Conclusion: Consistent Performance is Key

Dealing with high CPU usage and stuttering can quickly ruin the intense multiplayer experience of Battlefield™ 6. This automated PowerShell script offers the fastest, most reliable way to apply the essential thread optimization tweak for AMD Ryzen users. Enjoy smoother, more stable frame rates, and get back to dominating the battlefield!
