For me, a common app like MPC-HC media player which never had this much issue before now also is fine only once I set it to a full "7" compatibility meaning fully exclude. I bet this thread creator just has some apps also like this. ]]> https://www.displayfusion.com/Discussions/View/extremely-high-cpu-usage-from-df/?ID=8ed7980c-0e3e-473d-90fa-ecd480c01ac4#7 Wed, 29 Apr 2015 14:01:57 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/extremely-high-cpu-usage-from-df/?ID=8ed7980c-0e3e-473d-90fa-ecd480c01ac4#7 DisplayFusion Just sent you an email with some more troubleshooting stuff to try and send to us ]]> https://www.displayfusion.com/Discussions/View/extremely-high-cpu-usage-from-df/?ID=8ed7980c-0e3e-473d-90fa-ecd480c01ac4#6 Thu, 23 Apr 2015 19:36:44 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/extremely-high-cpu-usage-from-df/?ID=8ed7980c-0e3e-473d-90fa-ecd480c01ac4#6 DisplayFusion Thanks! For some reason there are a ton of TaskbarManager threads, which is definitely not normal, and most likely what's causing the CPU usage to be high. We'll have a closer look at these logs and see what we can figure out. I'll keep you posted as soon as we have more news! ]]> https://www.displayfusion.com/Discussions/View/extremely-high-cpu-usage-from-df/?ID=8ed7980c-0e3e-473d-90fa-ecd480c01ac4#5 Thu, 23 Apr 2015 15:04:28 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/extremely-high-cpu-usage-from-df/?ID=8ed7980c-0e3e-473d-90fa-ecd480c01ac4#5 DisplayFusion Unfortunately the problem has returned. It was fine for a couple of restarts, now it's back to hovering between 30%-70% CPU usage. I've tried disabling functions one by one until nothing was left, and it still occurs so I'm very confused. I have attached the latest log and troubleshooting info. ]]> https://www.displayfusion.com/Discussions/View/extremely-high-cpu-usage-from-df/?ID=8ed7980c-0e3e-473d-90fa-ecd480c01ac4#4 Tue, 21 Apr 2015 18:52:57 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/extremely-high-cpu-usage-from-df/?ID=8ed7980c-0e3e-473d-90fa-ecd480c01ac4#4 DisplayFusion Sounds great, thanks! ]]> https://www.displayfusion.com/Discussions/View/extremely-high-cpu-usage-from-df/?ID=8ed7980c-0e3e-473d-90fa-ecd480c01ac4#3 Mon, 20 Apr 2015 20:20:36 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/extremely-high-cpu-usage-from-df/?ID=8ed7980c-0e3e-473d-90fa-ecd480c01ac4#3 DisplayFusion The new beta actually does seem to have resolved it. At launch it was as high as before but after a minute or two it calmed right down and is now hovering around 0%-2%. Amazing!

I'll keep an eye on it and let you know if anything changes but I should be good to go for now. Thank you so much. ]]> https://www.displayfusion.com/Discussions/View/extremely-high-cpu-usage-from-df/?ID=8ed7980c-0e3e-473d-90fa-ecd480c01ac4#2 Mon, 20 Apr 2015 19:47:23 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/extremely-high-cpu-usage-from-df/?ID=8ed7980c-0e3e-473d-90fa-ecd480c01ac4#2 DisplayFusion Does it hit 30%+ CPU immediately after starting up DisplayFusion, or only after it's been running for a while?

We've just released DisplayFusion 7.2 Beta 4 as well, could you update to that and see if you still have this issue? If you do, could you let it run for 10-15 minutes or so, and then attach a new copy of the troubleshooting info? We've added some info to collect the CPU usage for each thread in DisplayFusion, to try and track down which thread is running up the CPU.

Thanks! ]]> https://www.displayfusion.com/Discussions/View/extremely-high-cpu-usage-from-df/?ID=8ed7980c-0e3e-473d-90fa-ecd480c01ac4 Mon, 20 Apr 2015 18:01:17 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/extremely-high-cpu-usage-from-df/?ID=8ed7980c-0e3e-473d-90fa-ecd480c01ac4 DisplayFusion I love DisplayFusion but I've had this issue for months and can't find a way to resolve it.

It just thrashes away at my system, hovering at anywhere from 30%-70% CPU usage and making my system unusable. As soon as I kill off the process, everything returns to normal.

I'm using Windows 7 SP2 on a domain with folder redirection, with three monitors from an Intel HD 4600 GPU. All I really use DisplayFusion for is multi-monitor taskbars, and setting wallpaper & login wallpaper. I have attached my DF log and Troubleshooting info, please help, I've tried everything.

I'm using the Beta version in a vain attempt to resolve the issue, but the issue has been present for many of the previous versions, and I was using the stable version up until 20-30 minutes ago with the exact same problems. ]]>
