If you still run into any trouble after updating, please let me know! ]]> https://www.displayfusion.com/Discussions/View/cpu-usage-permanently-high-since-using-4k-monitors/?ID=ab728c72-cbed-4f2d-9461-c1f2d9994e05 Mon, 13 Nov 2017 16:55:44 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/cpu-usage-permanently-high-since-using-4k-monitors/?ID=ab728c72-cbed-4f2d-9461-c1f2d9994e05 DisplayFusion Hello,

since I changed to a GTX1060 and two 4k monitors, Display Fusion is using between 10% and 25% CPU permanently. I also saw it use over a gigabyte of memory at one point. I checked if any compatibility options are on for the exe, but everything is off and default.

I'm not sure what is going on. (I'm not 100% sure it's started exactly when i switched monitors and graphics card, but it's when I first noticed its impact)

Debug output is attached. ]]>
