Currently I don't really have any workflows where I could naturally get the CPU closer to becoming a bottleneck to try to catch any impact systemwide, so I can only see it as #1 resource user with a decent margin in taskmanager any time I interact with it.

I've attached what little I can catch with procmon, resmon and perfmon.

Maybe globe spy37266 has more input as he is currently having the issue ]]> https://www.displayfusion.com/Discussions/View/windows-11-alt-tab-issue/?ID=c7ea8745-d8c9-4fcb-8c33-674617d5c234#15 Wed, 12 Jul 2023 17:32:14 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/windows-11-alt-tab-issue/?ID=c7ea8745-d8c9-4fcb-8c33-674617d5c234#15 DisplayFusion Thanks for testing it out! Are you grabbing those numbers from the Task Manager > Details tab?

Do you notice any performance degradation? ]]> https://www.displayfusion.com/Discussions/View/windows-11-alt-tab-issue/?ID=c7ea8745-d8c9-4fcb-8c33-674617d5c234#14 Wed, 12 Jul 2023 16:36:27 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/windows-11-alt-tab-issue/?ID=c7ea8745-d8c9-4fcb-8c33-674617d5c234#14 DisplayFusion Haven't been able to use this for a while but updated to the latest beta to test just for you guys

Alt tab in general seems a bit better, but if you mouse-over the alt tab preview window CPU utilization spikes from 0,3% to 11% (for comparison i'm playing Factorio multiplayer right now, and its only hitting 3-4% utilization)

moving mouse or right clicking over multi monitor taskbars also hits CPU with 6-8% extra cpu load ]]> https://www.displayfusion.com/Discussions/View/windows-11-alt-tab-issue/?ID=c7ea8745-d8c9-4fcb-8c33-674617d5c234#13 Wed, 12 Jul 2023 14:54:23 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/windows-11-alt-tab-issue/?ID=c7ea8745-d8c9-4fcb-8c33-674617d5c234#13 DisplayFusion Can you update to our latest beta and let me know if the issue persists?

Using the steps provided it resolves the slow Alt-Tabbing.
Thought this might have been resolved since this is an old thread. ]]> https://www.displayfusion.com/Discussions/View/windows-11-alt-tab-issue/?ID=c7ea8745-d8c9-4fcb-8c33-674617d5c234#11 Tue, 23 Nov 2021 17:09:09 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/windows-11-alt-tab-issue/?ID=c7ea8745-d8c9-4fcb-8c33-674617d5c234#11 DisplayFusion Hello,

stable 0,1% cpu load, so seems like culprit is clear ]]> https://www.displayfusion.com/Discussions/View/windows-11-alt-tab-issue/?ID=c7ea8745-d8c9-4fcb-8c33-674617d5c234#7 Thu, 11 Nov 2021 09:50:12 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/windows-11-alt-tab-issue/?ID=c7ea8745-d8c9-4fcb-8c33-674617d5c234#7 DisplayFusion Fresh launch all hooks re-enabled: DF cpu 0,4% & 71,4 MB ram

Jumping between active windows by clicking on multi monitor taskbars: DF cpu spikes to 5% temporarily, but drops back to 0,4%
t+90min DF cpu 1,3% 95,1 MB ram
t+2h DF cpu jumping between 1,4-2,2%,
t+4h DF cpu 4,7-5,2% 261 MB ram, same programs open. Average utilization seemed to increase gradually over time

starting settings changes
screen saver, already off
triggers, already off
key combinations, disabled no change
Multi-monitor taskbar, disabled -> drop down to 2% cpu
maximized window dragging between monitors, disabled -> spike up to 4,9-6,1% and stay there
maximized window dragging between monitors, re-enable -> marginally lower 4,5-5,5% (coincidental?)

edit:9 hours later now closing to 10% cpu load while i was out and computer idle, so definitely increasing over time ]]> https://www.displayfusion.com/Discussions/View/windows-11-alt-tab-issue/?ID=c7ea8745-d8c9-4fcb-8c33-674617d5c234#6 Wed, 10 Nov 2021 18:49:02 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/windows-11-alt-tab-issue/?ID=c7ea8745-d8c9-4fcb-8c33-674617d5c234#6 DisplayFusion Hello,

Interesting, if you re-enable those hooks, can you open the DisplayFusion Settings window and disable some of the settings listed (Triggers, Multi-Monitor Taskbars, Screen Saver, etc.) the next time the issue happens, and see if anything in particular fixes it up?

Thanks! ]]> https://www.displayfusion.com/Discussions/View/windows-11-alt-tab-issue/?ID=c7ea8745-d8c9-4fcb-8c33-674617d5c234#5 Tue, 09 Nov 2021 18:46:43 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/windows-11-alt-tab-issue/?ID=c7ea8745-d8c9-4fcb-8c33-674617d5c234#5 DisplayFusion usually firefox (twitch/youtube) with 10-20% and second is Displayfusion with 3-10%, but its hard to pinpoint what is triggering the jump in cpu load, as i might just be on the desktop doing nothing.

Disabling Application hooks helps somewhat, but still can go up to high utilization (i7-8700k), running as low priority process changes nothing ]]> https://www.displayfusion.com/Discussions/View/windows-11-alt-tab-issue/?ID=c7ea8745-d8c9-4fcb-8c33-674617d5c234#4 Tue, 09 Nov 2021 18:20:50 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/windows-11-alt-tab-issue/?ID=c7ea8745-d8c9-4fcb-8c33-674617d5c234#4 DisplayFusion Hello,

We'll definitely want to fix up that performance issue, which should fix up your alt tab issues as well when you re-enable application hooks. When your system slows down, if you open Task Manager > Processes, is anything high in usage?

Thanks! ]]> https://www.displayfusion.com/Discussions/View/windows-11-alt-tab-issue/?ID=c7ea8745-d8c9-4fcb-8c33-674617d5c234#3 Mon, 08 Nov 2021 19:38:44 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/windows-11-alt-tab-issue/?ID=c7ea8745-d8c9-4fcb-8c33-674617d5c234#3 DisplayFusion That did the trick, thanks a lot!

Though unfortunate side effect is that now main monitor is showing every monitors tray icons as duplicates, but at least its workable ]]> https://www.displayfusion.com/Discussions/View/windows-11-alt-tab-issue/?ID=c7ea8745-d8c9-4fcb-8c33-674617d5c234#2 Mon, 08 Nov 2021 19:20:23 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/windows-11-alt-tab-issue/?ID=c7ea8745-d8c9-4fcb-8c33-674617d5c234#2 DisplayFusion Hello,

After disabling Alt+Tab in the DisplayFusion Settings, can you set the Taskbar Mode to "Windows taskbar shows all windows, DisplayFusion shows relevant windows", and see if the issue persists?

Thanks! ]]> https://www.displayfusion.com/Discussions/View/windows-11-alt-tab-issue/?ID=c7ea8745-d8c9-4fcb-8c33-674617d5c234 Mon, 08 Nov 2021 15:14:41 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/windows-11-alt-tab-issue/?ID=c7ea8745-d8c9-4fcb-8c33-674617d5c234 DisplayFusion Hi,

I'm having some generic slow performance on DF, which i unceremoniously worked around by disabling global application hooks as problem feels too unspecified to easily troubleshoot. (slow taskbar window peek, DF itself opening/navigating slow, general feeling of sluggish system)

But the side effect is that alt+tab is only showing main monitor windows when DF alt+tab functionality is enabled OR disabled (looks as if DF is handling it even in disabled state in settings.)

Only shutting down DF seems to return windows own alt+tab handler with full functionality. So any way to keep DF from touching alt tab? ]]>
