I've never run into an issue where the service is also using a lot of CPU, it normally doesn't really do much at all.

Could you send me a debug log?

• On the DisplayFusion Settings > Troubleshooting tab, change the Logging drop-down to "L1: Log Minimal" and click Apply
• Reproduce the issue and note the time so we'll know where to check in the log file
• Click the "Export Info to File" button on the Settings > Troubleshooting tab
• Reply with the file attached
• Disable debug logging after sending the log

* 26% on DisplayFusion Pro on Steam 9.5
* 14% on Display Fusion Service

Though, I am using 4 monitors. ]]>
