Yup, I will have an eye on this and hope that I won't forget reporting :) I had made the change one Wednesday and saw no issues yesterday, but I'd like to check for a week to be sure. ]]> RE: Mouse lag in DF 9.7.1 beta 5 and Windows 10 20H2 https://www.displayfusion.com/Discussions/View/mouse-lag-in-df-971-beta-5-and-windows-10-20h2/?ID=1fe41dcb-c42e-4a35-ac8c-ae0ac1aa3e1c#51 Thu, 13 May 2021 17:10:00 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/mouse-lag-in-df-971-beta-5-and-windows-10-20h2/?ID=1fe41dcb-c42e-4a35-ac8c-ae0ac1aa3e1c#51 DisplayFusion Hello,

@Hoja Let me know how that works for you.

@AndrewMorison39070 Could you send me over a backup of your DisplayFusion settings? You can grab them in the options tab of the DisplayFusion Settings window, using the "Export Settings" button.

Thanks! ]]> RE: Mouse lag in DF 9.7.1 beta 5 and Windows 10 20H2 https://www.displayfusion.com/Discussions/View/mouse-lag-in-df-971-beta-5-and-windows-10-20h2/?ID=1fe41dcb-c42e-4a35-ac8c-ae0ac1aa3e1c#50 Thu, 13 May 2021 00:42:46 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/mouse-lag-in-df-971-beta-5-and-windows-10-20h2/?ID=1fe41dcb-c42e-4a35-ac8c-ae0ac1aa3e1c#50 DisplayFusion Hi Owen,

System was back to normal after removing DF.
My system is always set to 100 min and 100 max..

AMD 3900x, 32GB Ram, Samsung 860QVO SSD. Nvidia 1080.

Can you try the following steps and let me know if that helps?

1) Open the Windows Settings > Power & Sleep > Additional Power Settings
2) Click on "Change Plan Settings" > Change advanced power settings
3) Expand "Processor power management" and make sure Max processor state is 100, and try setting the minimum to something a bit higher

Thanks, beta 7 fixed the mouse lag issue that I was seeing.

I don't know if this is related, but I see a similar lag when opening the settings page. During the time the splash screen is playing, the system repeatedly lags. Once the splash screen is gone the lag stops.

Thanks,

Just to confirm, that since turning off:

Disabled System Hooks (application, Polling and Shell), my system has been running much better.

Please note, that it isn't just Mouse Lag, it relates to Windows and Applications when they are moved around.

Very happy to have been able to replicate it. Look forward to reading the release notes for future releases.

I couldn't work out what was causing my lag of mouse and display etc... But am seeing the same thing with 10 20H2 and 9.7.1 Beta 6. I was actually looking for issues with Taskbar on my second screen, appearing over the top of windows which are set to maximum. This is especially annoying with Edge or Chrome.

Happy to do some testing on this also.
To be honest, it feels like it has been happening for months.
I've had betas for ages, but didn't click.
