Thanks for the update. Unfortunately, I do not have a multi-monitor setup currently.

@JSF If you head to C:\Users\(YourUser)\AppData\Local\CrashDumps, is there anything listed for DisplayFusion? If so, could you send over the latest one?

@BundD Thanks for sending that updated log over, I'll pass it over to our developers to have a look into.

The CPU usage depends on your system, and which features in DisplayFusion are enabled. A bit of usage is expected as DisplayFusion uses background polling to keep it's features updated, but 8.3% is a bit high

I am beyond frustrated with the v10.x release. In all the years I have been using DisplayFusion, I have never seen such a problematic update from them.
I miss running DisplayFusion but I can't use it anymore until the CPU usage problem is fixed.
