Hello,

i noticed that DF is constantly using 5% of my CPU, sometimes spiking to 10%. I have three screens and seperate wallpapers from google images(had same issue with other image provider). The cycle interval is 60 minutes.
Wondered if you could have a look (debug attached) and see what I could optimize.

Thank you in advance!

As an update: I am currently running DF Pro 9.4.8 and I am stil seeing high spikes in CPU usage from time to time. DF is often running close to 20% CPU. I stopped using BINS months ago. Any thoughts?

Moved these to a new thread since the other one was pretty old.

If you guys disable the DisplayFusion wallpaper feature, does that make any difference?

just disabled it and initially it doesn't seem to make any difference. I turned logging on again and will work a while with it and provide another log later on.

I've got the same issue DisplayFusion hovering around 2.8-6% cpu usage. Wallpaper feature is not enabled, running v 9.4.3 as per latest in Steam. Log is attached.

If you guys enable the "Disable Application Hooks" option in the Settings > Advanced Settings window and restart DisplayFusion, does that make any difference?

Ok, if you disable any other features, Taskbars, Triggers, etc, do they make any difference?

I have same issues as others with frequent CPU spikes that I believe are causing my mouse to jump around and have jerky behavior.

It seems to happen a lot when I try to highlight text in firefox. What can I provide in terms of debug logs to help diagnose the root cause?

Edit: I've done some further testing on my end and have tried running without Display Fusion running and I am still getting weird CPU spikes as described above although less frequently without Display Fusion running.

I think the CPU spikes/lags are also coming from the Windows Defender Anti Malware Service Executable (MsMpEng.exe) and negative effects seems to be amplified when both DF and Anti-Malware Service Executable are running concurrently.

Do others seeing the CPU spikes also see what I described in my edit?

On an AMD Ryzen 7 2700 my spikes for Display Fusion go up to around ~1%, and MsMpEng.exe is constantly spiking to around ~5% when the issue is at it's worst.

Here is my log file. Display fusion on my system routinely runs in the 10-20 percent range.

@Don: I don't see anything out of the ordinary in your troubleshooting info. If you disable application hooks (Settings > Advanced Settings > Disable Application Hooks), does that make any difference?

I had to uninstall due to this issue. Computer also become more and more sluggish over time. Still have to observe, but uninstall seems to have solved it at first sight...

Does the "General: Run as a Low Priority Process" option in the DisplayFusion Advanced Settings make any difference (higher or lower) in the CPU usage? Note that you need to restart DisplayFusion after changing that setting.

Another test for you guys to try if you still have DF installed: Can you disable all other applications from startup except for DF, reboot, then see if DF still runs up the CPU?

I will test running as low priority process first and then disabling hooks second and let you know if issue seems to be resolved.

I'm still not 100% certain the fault lies with with DisplayFusion on my end since I've seen the sluggish CPU spikes happen when I had the process killed. I think it may be a combination of Windows Defender realtime protection and DF potentially amplifying the impact of Windows Defender spikes somehow.
