Can you try updating to our latest beta, and see if there's any change in usage?

Let me know how that works! ]]> https://www.displayfusion.com/Discussions/View/displayfusion-crushing-my-cpu/?ID=60ca0113-96af-450e-a6d6-b3d753dca86d#3 Fri, 02 Apr 2021 22:26:44 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/displayfusion-crushing-my-cpu/?ID=60ca0113-96af-450e-a6d6-b3d753dca86d#3 DisplayFusion Here's the log file with debugging on. CPU use was over 35% the entire time it ran, and spiked to over 50% in the few seconds before I exported the logs ]]> https://www.displayfusion.com/Discussions/View/displayfusion-crushing-my-cpu/?ID=60ca0113-96af-450e-a6d6-b3d753dca86d#2 Fri, 02 Apr 2021 22:24:13 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/displayfusion-crushing-my-cpu/?ID=60ca0113-96af-450e-a6d6-b3d753dca86d#2 DisplayFusion Oh, and disabling "Enable TitleBar Buttons" did not help. (Plus, those are one of my favorite parts of DisplayFusion, so I wouldn't want to have to turn them off anyway.)

Unchecking that box actually caused DF to spike clear up to 50% CPU usage. I'm seeing now that any time I do something with DF, such as open the app, open settings, apply settings, etc, it spikes up to the 50% range briefly, before settling back to just under 40%. ]]> https://www.displayfusion.com/Discussions/View/displayfusion-crushing-my-cpu/?ID=60ca0113-96af-450e-a6d6-b3d753dca86d Fri, 02 Apr 2021 22:19:02 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/displayfusion-crushing-my-cpu/?ID=60ca0113-96af-450e-a6d6-b3d753dca86d DisplayFusion Hello. I'm having a problem where DF is constantly using 38%+ of my CPU (Windows 10). I have it installed on two extremely similar computers, and this is only happening on one of the two.

The computer is Windows 10, Version 20H2, OS build 19042.867, and I have two monitors running.

I'm running v9.7.1. I've attached a copy of my Troubleshooting log. I've also turned on minimal logging as of today, in case that is necessary. ]]>
