This is on Windows 8.1.1 x64 Professional. DisplayFusion.exe in Beta 4 of DisplayFusion is constantly clocking from 0.3 to 2.0% CPU utilization even when the system is idle. I have attached some troubleshooting logs.

This issue with Beta 5 is showing no improvement whatsoever. I have attached new logs. In fact, I think it is even more CPU active.

Maybe it is the wrong BETA 5 version. Because the Download link is saying Version 6.1.0 Beta 5 but the download itself is still Version 6.0.1 Beta5 .
I have that problem also when the DisplayFusion automatic update starts. Its now in a loop. Everytime the auto updater says new version 6.1.0 Beta 5 is out, because it keeps installing 6.0.1 Beta 5.

That does not appear to be the problem.

I reverted back to Beta 3 and the degree of CPU utilization did not decrease. So I went back to 6.0c and the CPU activity remains excessive....approximately the same as Beta 4/5. It's almost a continuous 0.4-2.0% CPU utilization.

5.1.1 is showing constant CPU activity; however, the magnitude is less at 0.15% to 1.10% as observed over a 5 minute period viewing with MS's Process Explorer.

Maybe I'm just now noticing the constant CPU activity of DisplayFusion. It just seems to now be showing up constantly in my "Top Process Monitor" gadget whereas it appeared infrequently before.

It does not go away. However, its magnitude is less...more like 0.3%-1.3%. But its a constant CPU user.

The DisplayFusion.exe Page Faults seems excessive to me. Indication of a problem ??

Updated to 6.1: Disabling the TitleBar Buttons has no visible affect on decreasing the constant CPU usage or its magnitude.

Hi Keith,
I think I'm experiencing something similar - I just updated DisplayFusion to 6.1, and now its eating up 3-5% of my CPU at idle, significantly more than 6.0 (although 6.0 was also pretty bad). Unlike siliconman I'm running Windows 7 x64.

Disabling the taskbar and application hooks have made no difference to the constant CPU load. I'm going to see what else I can turn off to see if I can narrow things down further.

Disabling application hooks does not change the CPU issue. The magnitude remained the same as well.

Using msconfig, I booted into Safe Mode on Windows 8.1.1 x64. Unfortunately in this mode only the main monitor is detected and useable. I went ahead and activated DisplayFusion and could see no CPU activity....which I suppose is expected with only the main monitor active.

Do you know of a way to make the other monitors active when running in Safe Mode?

In Windows 7 SP1 x64, booted to safe mode, DisplayFusion continued to consume 2-3% CPU with no activity on my machine; even with just the one monitor.

Would a Task Scheduler dump of DisplayFusion.exe help in analyzing this problem? If so or possible, I'll take one and upload it to you if you wish. The zipped size of this dump is 98.7 megabytes, so please provide instructions for uploading it.

I did a recheck on DisplayFusion.exe's activity when booted in Safe Mode. With Process Explorer on a 1 second scan cycle, I do see constant CPU activity by DisplayFusion.exe. Its magnitude is from 0.02 to 0.40 from 1 second scan to 1 second scan. Just observing via the Task Manager, this does not show up.

I did a complete uninstall and registry cleaning for DisplayFusion and then re-installed it. That did not help at all.

I sent you an email requesting the FTP account info.

Great. I'm glad that it is showing up on one of your machines. Thanks for your attention to this issue. DF has always been very small/good on CPU usage and I would not like to see that deteriorate.
