Alternatively, check the official repository under "MSI-Utility" by user 'Foxed'.
A device pulls a physical wire low or high to signal the CPU. If multiple devices share a line, the CPU must poll each device to find the source, causing processing delays.
A: Yes. It works perfectly on Windows 10, 11, and even Windows 8.1/7 (limited driver support).
If you set every single device to "High" priority, you defeat the purpose of priority routing, creating a new performance bottleneck. Keep "High" reserved strictly for your primary graphics card. Troubleshooting Common Issues My screen went black after restarting, what do I do?
