Also yes, I am running beta 11 right now, 3.1.8.111, and the problem continues to happen. I have found that it doesn't always happen, for example right now it is not happening. If I reboot my machine it very well may start happening again so I am only putting it to sleep when I take my laptop with. I haven't figured out what the link is that causes it to happen versus not to happen. When it does happen, it follows a very specific timing pattern of about once every minute, and each time it happens it lasts about 3-4 seconds of 100% CPU utilization. I would imagine this would make it a little easier to find, since it must be related to an internal timer.

I have DisplayFusion turned off for now as the intermittent lags I 'm seeing are very annoying, ]]> RE: 3.1.8 CPU spikes - machine unresponsive https://www.displayfusion.com/Discussions/View/318-cpu-spikes-machine-unresponsive/?ID=34d54b60-1823-453b-be9f-bcae996057b7#24 Mon, 07 Jun 2010 04:58:13 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/318-cpu-spikes-machine-unresponsive/?ID=34d54b60-1823-453b-be9f-bcae996057b7#24 DisplayFusion does turning off all of the components of MSE fix it as well? You have to test the other way as well

also doese this happen in the latest beta? ]]> RE: 3.1.8 CPU spikes - machine unresponsive https://www.displayfusion.com/Discussions/View/318-cpu-spikes-machine-unresponsive/?ID=34d54b60-1823-453b-be9f-bcae996057b7#23 Mon, 07 Jun 2010 03:29:01 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/318-cpu-spikes-machine-unresponsive/?ID=34d54b60-1823-453b-be9f-bcae996057b7#23 DisplayFusion I am noticing this exact same problem on my machine running 3.1.8. It happens almost once a minute and causes my computer to become unresponsive for about 3-4 seconds. I am also running Windows 7 64 bit on a duo-core laptop, although an HP (not that the brand matters as much as the internals). When this happens I can't even type in whatever window I have open it is so unresponsive. I have done a bit of logging and found it to be conclusively DisplayFusion causing the problem. Closing DisplayFusion fixes the problem. I had thought this was the result of Microsoft Security Essentials since I had installed that around the time this happened so it could be related to that, although all of my debugging has pointed to DisplayFusion oddly enough.

Let me know if there is anything I can offer to help debug this issue.

I was using Kaspersky 2010 for AV but have now changed to Nod32. This hasn't changed the symptoms.

If I set the affinity on the DisplayFusion process to a single core, there are no subsequent CPU spikes other than when the background changes.

Very strange. ]]> RE: 3.1.8 CPU spikes - machine unresponsive https://www.displayfusion.com/Discussions/View/318-cpu-spikes-machine-unresponsive/?ID=34d54b60-1823-453b-be9f-bcae996057b7#19 Mon, 17 May 2010 13:30:35 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/318-cpu-spikes-machine-unresponsive/?ID=34d54b60-1823-453b-be9f-bcae996057b7#19 DisplayFusion I'm here, just trying to get caught-up.

Can you try disabling the system hooks on the Troubleshooting tab? I'm interested to see if it is the hooks causing the lockups. Are you using any anti-malware/anti-virus/firewall software as well? ]]> RE: 3.1.8 CPU spikes - machine unresponsive https://www.displayfusion.com/Discussions/View/318-cpu-spikes-machine-unresponsive/?ID=34d54b60-1823-453b-be9f-bcae996057b7#18 Thu, 13 May 2010 09:51:07 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/318-cpu-spikes-machine-unresponsive/?ID=34d54b60-1823-453b-be9f-bcae996057b7#18 DisplayFusion

BUT, have found a solution of sorts - tried setting the processor affinity from both cores to only one. Haven't seen any CPU spikes or machine stutters/slowdowns since. Strange but true

Only problem is that with this solution I have to manually set the affinity every time DF runs.

FYI - I'm running Windows 7 Ultimate 64 bit on a core2duo-based Dell Vostro 1500 laptop. ]]> RE: 3.1.8 CPU spikes - machine unresponsive https://www.displayfusion.com/Discussions/View/318-cpu-spikes-machine-unresponsive/?ID=34d54b60-1823-453b-be9f-bcae996057b7#12 Fri, 30 Apr 2010 21:28:32 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/318-cpu-spikes-machine-unresponsive/?ID=34d54b60-1823-453b-be9f-bcae996057b7#12 DisplayFusion Well first off do you have any other program that does anything similar at all to anything DF does?

Any help appreciated the only solution at the moment is to turn off DisplayFusion. :-(

What I have been experiencing is a general slow down/pause of other apps e.g. Media Center. If I monitor the DisplayFusion.exe process it normally spikes to around 40% during the pause. The DisplayFusion activity is happening even when there is no change to the desktop backgrounds (laptop and monitor) and even if I limit the background selections to a handful of pictures.

I use Skype quite a bit and the pauses can cut off the call I'm on. I've used DisplayFusion for a while and can't really recall when I first started noticing this but if there is any other debugging/info I can provide let me know.

I've attached a snapshot of some of the activity spikes I've been experiencing.

Thanks. ]]> RE: 3.1.8 CPU spikes - machine unresponsive https://www.displayfusion.com/Discussions/View/318-cpu-spikes-machine-unresponsive/?ID=34d54b60-1823-453b-be9f-bcae996057b7#8 Fri, 23 Apr 2010 18:24:37 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/318-cpu-spikes-machine-unresponsive/?ID=34d54b60-1823-453b-be9f-bcae996057b7#8 DisplayFusion Sorry for the delay. I did look at the log file, and unfortunately everything looks normal. When the pause happens, does the computer slow down, or do all the application windows actually become unresponsive and freeze? ]]> RE: 3.1.8 CPU spikes - machine unresponsive https://www.displayfusion.com/Discussions/View/318-cpu-spikes-machine-unresponsive/?ID=34d54b60-1823-453b-be9f-bcae996057b7#7 Thu, 15 Apr 2010 08:58:58 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/318-cpu-spikes-machine-unresponsive/?ID=34d54b60-1823-453b-be9f-bcae996057b7#7 DisplayFusion Anyone get a chance to look at my log? :-)
