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.

Thanks! There are some interesting lines in the log, so we'll hopefully be able to get this fixed up for Beta 5 :)

We've just released a new DisplayFusion beta version (http://www.displayfusion.com/Download/Beta/) and this issue should be all fixed up. Please let us know if you run into any trouble after updating.

Thanks!

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.

It was the correct beta, we just had the version numbers messed up in the updater. Should be fixed now.

@siliconman01: Can you try rolling back to Beta 3 and let me know if the CPU usage issue goes away?

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.

Ok, glad to see it's not just in the recent betas then :)

If you disable the DisplayFusion taskbar (Settings > Taskbar tab), does the CPU usage go down?

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 ??

Nah, they're likely soft faults (you can check in the Windows Resource Monitor to make sure they're not hard faults).

If you also disable the TitleBar Buttons, does the CPU usage decrease more?

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

Ok, what about if you disable the Application Hooks in the Settings > Advanced Settings window and then restart DisplayFusion? I apologize if it sounds like I'm stabbing in the dark, but I more or less am, since I can't reproduce the issue here, and the debug logs weren't helpful :(

Just trying to narrow down with feature(s) in DisplayFusion might be causing the CPU to constantly be in use.

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.

Ok, can you do a quick test to verify that it's not a conflict with some other software? Can you try booting Windows into Safe Mode, then launch DisplayFusion and check the CPU usage?

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. :-[

Some CPU usage is expected, as DisplayFusion needs to do a lot of polling for some of the features to work correctly. For the Process Monitor dump, I can give you an FTP account to upload them to. Can you email me at support@displayfusion.com for the details?

Thanks!

Ok, the task manager dump didn't have much useful info in it, but the good news is that I can see an increase in CPU usage on a test machine here between the older and newer versions as well. We'll work on that here, and hopefully can track this down :)

Thanks!

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. ;)
