Could you try disabling it on the DisplayFusion Settings > Alt+Tab tab, apply the settings, then restart DisplayFusion and see if that makes any difference? ]]> https://www.displayfusion.com/Discussions/View/high-cpu-usage/?ID=3853a316-f98c-45a2-b997-cf9eb6858f5a#2 Mon, 10 Jun 2019 17:55:15 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/high-cpu-usage/?ID=3853a316-f98c-45a2-b997-cf9eb6858f5a#2 DisplayFusion Is there a common app you have running frequently? I've found that if some apps redraw their window frequently and have more CPU use themselves maximized than minimized, it will increase DF CPU processing. ]]> https://www.displayfusion.com/Discussions/View/high-cpu-usage/?ID=3853a316-f98c-45a2-b997-cf9eb6858f5a Mon, 10 Jun 2019 14:48:06 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/high-cpu-usage/?ID=3853a316-f98c-45a2-b997-cf9eb6858f5a DisplayFusion I am running a DF 9.5 pro on a Windows 10 1809 PC. Over the past week or so I have had CPU problems and have found that DF is usign and average of 12-20% CPU and frequently 40-60%. After reading some postsI disabled that application hooks this does not appear to have helped. I see like some of the others that more Chrome windows cause higher CPU but I am currently tryign not to use Chrome. I also verified that the Areo settings are set to "Don't change the Aero color". I have not looked at the logs but I did set the logging to detailed for a while when this was happening they are attached. I have changed back to log level 0 and still have Display Fusion on the top of my CPU usage list. ]]>
