Enhancing Compatibility of TrackIR5 with Prepar3D v5 on Advanced Computer Systems

It sounds like you're experiencing a unique challenge with TrackIR5 integration on your new, high-specification system, particularly with Prepar3D v5. Given your detailed setup and the steps you've already taken, let's delve into a comprehensive approach to troubleshoot and hopefully resolve this issue.

Firstly, it's commendable that you've attempted the usual fixes such as driver updates and software reinstalls. These are always the first steps in troubleshooting peripheral device issues. However, given the complexity and specificity of flight simulation setups, sometimes more nuanced measures are necessary.

Step 1: Compatibility Mode and Administrator Rights
Ensure that both Prepar3D and TrackIR software are set to run in compatibility mode for an earlier version of Windows, such as Windows 10. Right-click on the application shortcut, go to Properties -> Compatibility, and select the compatibility mode. Also, check 'Run this program as an administrator' to grant it necessary permissions.

Step 2: Direct SimConnect Integration
Prepar3D v5, being a sophisticated platform, heavily relies on SimConnect for third-party integration. Verify that TrackIR's SimConnect version is compatible with your Prepar3D v5. Sometimes, mismatched versions can lead to non-communication between the software and the peripheral.

Step 3: USB Power Management
Windows 11 introduces more aggressive power management strategies, which could inadvertently affect peripheral devices. Go to Device Manager, find USB Root Hub (USB 3.0) properties, and under Power Management, uncheck 'Allow the computer to turn off this device to save power'. This ensures constant power supply to TrackIR, eliminating disconnects during operation.

Step 4: Firewall and Antivirus Exceptions
Occasionally, firewall and antivirus software can block communication between TrackIR and Prepar3D. Adding exceptions for both applications in your security software might be necessary to ensure uninterrupted communication.

Step 5: Configuring Prepar3D.cfg
Editing the Prepar3D.cfg file can sometimes enhance compatibility. Adding specific entries related to TrackIR can force Prepar3D to recognize and prioritize the device. However, proceed with caution and ensure you have backups before modifying configuration files.

Step 6: Community and Support Forums
Engage with the community on forums such as Fly Away Simulation and the official Prepar3D forums. Many users share similar setups and might have encountered and resolved the same issue. Additionally, reaching out to Natural Point's support can provide insights specific to TrackIR's integration with Prepar3D.

• Compatibility checks and adjustments
• Direct intervention via SimConnect
• USB power settings optimization
• Firewall and antivirus configurations
• Advanced Prepar3D.cfg tweaks
• Community engagement and official support

Remember, flight simulation platforms and peripherals like TrackIR are constantly evolving, with updates and patches frequently addressing compatibility issues. Keeping software up-to-date is crucial.

Lastly, given the sophistication of your setup, ensure that all hardware drivers, especially for your NVIDIA GeForce RTX 4090, are current. Driver incompatibilities can sometimes manifest in peripheral malfunctions.

I hope these steps guide you towards a resolution. Please keep us updated on your progress, and don't hesitate to provide more details or ask for further clarification.
