From what I can tell the biggest hitches seem to occur whenever Focus changes in Windows. There will be a brief period of time, perhaps less than a second or up to several seconds where performance is absolutely awful in the newly selected program and then things will return to normal.

There also does seem to be consitently poor performance in Explorer windows regardless of Focus change events, it's possible these are two separate issues.

EDIT: I'm wondering if by downloading old versions I might be able to track down the release that introduced these bugs, as I'm fairly sure they weren't present when I first started using DF...

EDIT 2: It seems that by changing the Aero Color Settings to Don't change has fixed both of the issues for me. Does anyone else get that result? ]]> https://www.displayfusion.com/Discussions/View/explorer-less-responsive-with-displayfusion-open/?ID=eec06589-b0ca-460f-9bce-f48e5e73df3c#29 Fri, 27 Sep 2019 15:08:33 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/explorer-less-responsive-with-displayfusion-open/?ID=eec06589-b0ca-460f-9bce-f48e5e73df3c#29 DisplayFusion @pfig: Thanks for the debug log! I will forward it over to our devs so that they can check it out. ]]> https://www.displayfusion.com/Discussions/View/explorer-less-responsive-with-displayfusion-open/?ID=eec06589-b0ca-460f-9bce-f48e5e73df3c#28 Fri, 27 Sep 2019 11:56:17 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/explorer-less-responsive-with-displayfusion-open/?ID=eec06589-b0ca-460f-9bce-f48e5e73df3c#28 DisplayFusion Hi Keith, I believe I'm having the same performance issue here. I've been seeing this for months, just didn't have the time to figure out the cause until now. If I close DF, everything is fine. As soon as DF is running, I will have sporadic performance issues when it comes to explorer. The easiest way for me to duplicate this is simply to hover over the taskbar and observe the previews. The main taskbar always works fine. But about half the time, the DF extended taskbar items will show a very delayed preview, if at all. Clicks, etc, are also very delayed on the extended monitors when this is happening.

Also, I tried disabling application hooks, but still observed performance issues.

I've attached a debug log. ]]> https://www.displayfusion.com/Discussions/View/explorer-less-responsive-with-displayfusion-open/?ID=eec06589-b0ca-460f-9bce-f48e5e73df3c#27 Fri, 05 Apr 2019 18:59:01 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/explorer-less-responsive-with-displayfusion-open/?ID=eec06589-b0ca-460f-9bce-f48e5e73df3c#27 DisplayFusion It shouldn't, I've got 2 4K monitors + a 1080p monitor here without issues. If you disable application hooks (Settings > Advanced Settings > Disable Application Hooks) and restart DisplayFusion, does that make any difference? ]]> https://www.displayfusion.com/Discussions/View/explorer-less-responsive-with-displayfusion-open/?ID=eec06589-b0ca-460f-9bce-f48e5e73df3c#26 Fri, 05 Apr 2019 18:23:21 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/explorer-less-responsive-with-displayfusion-open/?ID=eec06589-b0ca-460f-9bce-f48e5e73df3c#26 DisplayFusion FWIW I have two ultrawide monitors. I wonder if performance degrades as a factor of screen real estate? ]]> https://www.displayfusion.com/Discussions/View/explorer-less-responsive-with-displayfusion-open/?ID=eec06589-b0ca-460f-9bce-f48e5e73df3c#25 Fri, 05 Apr 2019 17:49:31 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/explorer-less-responsive-with-displayfusion-open/?ID=eec06589-b0ca-460f-9bce-f48e5e73df3c#25 DisplayFusion BTW, I'm using a 49" ultrawide monitor - that's not bad data in the logs ]]> https://www.displayfusion.com/Discussions/View/explorer-less-responsive-with-displayfusion-open/?ID=eec06589-b0ca-460f-9bce-f48e5e73df3c#24 Fri, 05 Apr 2019 17:47:53 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/explorer-less-responsive-with-displayfusion-open/?ID=eec06589-b0ca-460f-9bce-f48e5e73df3c#24 DisplayFusion To be clear, I uninstalled it after I sent those logs.

The DF troubleshooting info is showing that the VDM DLL is still injected in DisplayFusion.exe, so I'm wondering if that might be contributing to the issues you're having. ]]> https://www.displayfusion.com/Discussions/View/explorer-less-responsive-with-displayfusion-open/?ID=eec06589-b0ca-460f-9bce-f48e5e73df3c#22 Fri, 05 Apr 2019 15:49:59 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/explorer-less-responsive-with-displayfusion-open/?ID=eec06589-b0ca-460f-9bce-f48e5e73df3c#22 DisplayFusion I actually just briefly tried it the other day.

Performance eventually degraded until I had to close DF again. ]]> https://www.displayfusion.com/Discussions/View/explorer-less-responsive-with-displayfusion-open/?ID=eec06589-b0ca-460f-9bce-f48e5e73df3c#17 Wed, 03 Apr 2019 16:48:07 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/explorer-less-responsive-with-displayfusion-open/?ID=eec06589-b0ca-460f-9bce-f48e5e73df3c#17 DisplayFusion I have never seen it actually crash. I just had to close it again however. After rebooting yesterday and seeing my system become responsive again, it has once again deteriorated forcing me to close DF - and now everything works smoothly. I have a very powerful system here so it's frustrating to see this happen. It seems to affect performance in every single app. I love DF's features and hope there's a way to resolve this. ]]> https://www.displayfusion.com/Discussions/View/explorer-less-responsive-with-displayfusion-open/?ID=eec06589-b0ca-460f-9bce-f48e5e73df3c#16 Wed, 03 Apr 2019 16:27:17 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/explorer-less-responsive-with-displayfusion-open/?ID=eec06589-b0ca-460f-9bce-f48e5e73df3c#16 DisplayFusion Ok, and if you leave it running long enough, does DisplayFusion eventually crash? ]]> https://www.displayfusion.com/Discussions/View/explorer-less-responsive-with-displayfusion-open/?ID=eec06589-b0ca-460f-9bce-f48e5e73df3c#15 Tue, 02 Apr 2019 16:09:52 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/explorer-less-responsive-with-displayfusion-open/?ID=eec06589-b0ca-460f-9bce-f48e5e73df3c#15 DisplayFusion It happens soon after it loads. ]]> https://www.displayfusion.com/Discussions/View/explorer-less-responsive-with-displayfusion-open/?ID=eec06589-b0ca-460f-9bce-f48e5e73df3c#14 Tue, 02 Apr 2019 14:04:11 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/explorer-less-responsive-with-displayfusion-open/?ID=eec06589-b0ca-460f-9bce-f48e5e73df3c#14 DisplayFusion Thanks Eric!
