Interesting, can you try to enable them 1 by 1, and see if there's one in particular that causes the spike?

Thanks! ]]> https://www.displayfusion.com/Discussions/View/high-cpu-usage/?ID=55fed1ce-da61-421f-a248-c4018a54ca3f#5 Sun, 28 Feb 2021 13:36:18 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/high-cpu-usage/?ID=55fed1ce-da61-421f-a248-c4018a54ca3f#5 DisplayFusion Hello, sorry for the long wait, i have been waiting for the situation to occur since its random.

I disabled all 3 hooks and the cpu dropped from 25% to around 10% and after a little while dropped to 5%. Does this mean i need to keep the hooks disabled until a future update or is there anything i can change that's causing the hooks to use high CPU usage?

Interesting, if you head into the advanced settings in DisplayFusion, can you disable all 3 hooks (applications, polling, and shell), and see if there's any difference in CPU usage?

It's not at any specific moment or after i do a specific activity, it just seems random. ]]> https://www.displayfusion.com/Discussions/View/high-cpu-usage/?ID=55fed1ce-da61-421f-a248-c4018a54ca3f#2 Tue, 23 Feb 2021 19:02:24 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/high-cpu-usage/?ID=55fed1ce-da61-421f-a248-c4018a54ca3f#2 DisplayFusion Hello,

Did this first start happening after any updates (Display Fusion or windows)?

Thanks! ]]> https://www.displayfusion.com/Discussions/View/high-cpu-usage/?ID=55fed1ce-da61-421f-a248-c4018a54ca3f Tue, 23 Feb 2021 01:20:01 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/high-cpu-usage/?ID=55fed1ce-da61-421f-a248-c4018a54ca3f DisplayFusion Hello, i have been using Display Fusion Pro since 2017 and never had any issues until recently. I started getting 10-30% CPU usage, sometimes it started randomly and other's its as soon as i launch the program.

Since this issue has started i have tried updating windows to 20H2, updated to the latest 9.7.2 Beta 5 & tried disabling Application Hooks and nothing has worked.

I have attached my latest Debug Info. ]]>
