This article will guide you through troubleshooting steps, potential fixes, and tips to resolve Unity Oculus Link not working on Windows 11, ensuring you can get back to your immersive VR projects.
Why Does Unity Oculus Link Not Work on Windows 11?
Before diving into solutions, understanding the common reasons for this issue can save time. Windows 11 introduces new compatibility requirements, security features, and driver updates that can interfere with Oculus Link’s performance. Here are the primary causes:
1. Driver Compatibility Issues
Outdated or incompatible graphics drivers often cause Oculus Link to fail on Windows 11. Since VR relies on GPU power, this becomes critical.
2. Windows 11 Security Settings
Windows 11 includes enhanced security settings like virtualization-based security (VBS) and core isolation. These features may block Oculus Link from working properly.
3. Outdated Oculus Software
Using an outdated version of the Oculus app or firmware can create communication issues between the headset and Unity on Windows 11.
4. Faulty USB or Cable Connection
A loose or incompatible USB cable can prevent Oculus Link from establishing a stable connection to your PC.
5. Incorrect Unity Settings
Improper configurations in Unity’s XR plugin management can lead to connectivity issues with Oculus Link.
Step-by-Step Guide to Fix Unity Oculus Link Not Working on Windows 11
1. Update Graphics Drivers
Graphics drivers are essential for running VR applications smoothly. Outdated drivers can cause crashes or prevent the headset from connecting.
How to Update Drivers:
- Open the Device Manager by searching for it in the Windows 11 search bar.
- Expand the Display Adapters section.
- Right-click your GPU (e.g., NVIDIA or AMD) and select Update Driver.
- Choose Search automatically for drivers.
- Restart your PC after updating the driver.
Alternatively, visit the official NVIDIA or AMD website to download the latest driver version manually.
2. Disable Virtualization-Based Security (VBS)
VBS and core isolation can conflict with Oculus Link by restricting access to certain system resources.
Steps to Disable VBS:
- Press Windows + I to open the Settings menu.
- Navigate to Privacy & Security > Windows Security > Device Security.
- Under Core Isolation, click on Core Isolation Details.
- Toggle Memory Integrity off.

Disabling VBS may resolve performance and compatibility issues with Oculus Link on Windows 11.
3. Ensure Oculus App and Firmware Are Updated
Using outdated Oculus software often results in connectivity problems. Updating both the desktop app and headset firmware is essential.
Steps to Update Oculus Software:
- Open the Oculus app on your PC.
- Go to Settings > General and check for updates.
- Update the firmware of your Oculus headset by connecting it to Wi-Fi and navigating to Settings > About > Update.
Keeping your Oculus environment up-to-date ensures compatibility with Unity and Windows 11.
4. Check USB Connection and Cable
A faulty or incompatible USB cable can block Oculus Link from working. The quality of your connection plays a vital role in performance.
How to Verify Your Cable and Connection:
- Use the official Oculus Link cable or a high-quality USB-C 3.0 cable for optimal performance.
- Connect your headset to a USB 3.0 port on your PC.
- Test the cable by running the Oculus Compatibility Tool to ensure proper data transfer speeds.
- Avoid using USB hubs or extension cords, as they may degrade the connection.
A stable USB connection is crucial for running VR apps in Unity on Windows 11.
5. Configure Unity XR Plugin Management
Improper Unity settings often prevent Oculus Link from functioning properly. Unity requires specific configurations to recognize VR headsets.
Steps to Set Up Unity XR:
- Open Unity and go to Edit > Project Settings.
- Navigate to XR Plugin Management in the left-hand menu.
- Install the Oculus XR Plugin from the Unity Package Manager.
- Enable Oculus under the PC, Mac, & Linux Standalone tab.
- Ensure that the correct rendering API (DirectX 11 or 12) is selected under Player Settings > Other Settings.
Restart Unity after configuring the settings to ensure Oculus Link works seamlessly.
6. Adjust Oculus Debug Tool Settings
The Oculus Debug Tool can help fine-tune settings and identify issues affecting Oculus Link.
How to Use Oculus Debug Tool:
- Open the Oculus Debug Tool located in the Support > Oculus Diagnostics folder.
- Set the Encode Bitrate to a lower value (e.g., 200 Mbps) to optimize performance.
- Check for any performance metrics that indicate connection issues.
Fine-tuning these settings can improve Oculus Link’s stability and functionality on Windows 11.
7. Disable Background Apps
Unnecessary background applications can interfere with Oculus Link’s performance by consuming system resources.
How to Disable Background Apps:
- Press Ctrl + Shift + Esc to open Task Manager.
- Go to the Startup tab and disable unnecessary programs.
- Close resource-intensive apps like Chrome, Discord, or any streaming software while running Oculus Link.
This ensures your PC’s resources are fully dedicated to running Unity and Oculus Link efficiently.
