We're pretty limited with this in Windows 11, but if you disable your tray icons on every DisplayFusion taskbar that should stop the stuttering as it won't continue to poll for them.

@Slegnor Can you send me a video of the issue? ]]> RE: Severe FPS Drops & Alt+Tab Issues Caused by DisplayFusion https://www.displayfusion.com/Discussions/View/severe-fps-drops-alttab-issues-caused-by-displayfusion/?ID=01999ff5-cc0a-70b5-a53d-7c6773d6ba48#45 Sun, 15 Feb 2026 14:19:01 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/severe-fps-drops-alttab-issues-caused-by-displayfusion/?ID=01999ff5-cc0a-70b5-a53d-7c6773d6ba48#45 DisplayFusion I have also been seeing this issue in Rust, and disabling the Hook solved the issue BUT I still have the other issue mentioned, the tiny Alt-Tab thumbnails, has this been addressed? ]]> RE: Severe FPS Drops & Alt+Tab Issues Caused by DisplayFusion https://www.displayfusion.com/Discussions/View/severe-fps-drops-alttab-issues-caused-by-displayfusion/?ID=01999ff5-cc0a-70b5-a53d-7c6773d6ba48#44 Fri, 13 Feb 2026 21:11:21 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/severe-fps-drops-alttab-issues-caused-by-displayfusion/?ID=01999ff5-cc0a-70b5-a53d-7c6773d6ba48#44 DisplayFusion

We've released a new beta with some added logging. In the DisplayFusion Advanced Settings, could you set the "Log Level for Hooks" to "1" and reboot, then grab a fresh log? Here are the steps again for reference:

  • On the DisplayFusion Settings > Troubleshooting tab, change the Logging drop-down to "L1: Log Minimal" and then click "Clear Log"
  • Reproduce the issue and note the time so we'll know where to check in the log file
  • Click the "Export Info to File" button on the Settings > Troubleshooting tab
  • Reply with the file attached
  • Disable debug logging after sending the log


I've gone through the steps:
- Updated to the latest DF beta
- Set "Log Level for Hooks" to "1" in Advanced Settings
- Under the Troubleshooting tab I set the log level to "L1: Log Minimal"
- Pressed the "Clear Log" button
- Started playing Arc Raiders
- Noted the timing of the frame hiccups during my game session

I noted the first time around 21:35:27, and after that I noticed it happened around every minute after, shifting ever so slightly later over time.

I was curious about the log itself so looking at the Debug.log text file I noted that this sequence of logs relating to 'tray icon reloading' seemed to line up exactly with the timing I experienced. The duration of the freeze also seems to line up with all the "TrayIcons:NIM_ADD" lines. (see attached debug.png)

EDIT:
I also did a run with applications hooks disabled after that, and it seems this skips these icon reloads (log message reads "[TrayIcons] skipping full enum, taskbar hooks not loaded" in those cases), which also meant I didn't experience the stutter every minute. ]]> RE: Severe FPS Drops & Alt+Tab Issues Caused by DisplayFusion https://www.displayfusion.com/Discussions/View/severe-fps-drops-alttab-issues-caused-by-displayfusion/?ID=01999ff5-cc0a-70b5-a53d-7c6773d6ba48#43 Thu, 12 Feb 2026 00:38:38 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/severe-fps-drops-alttab-issues-caused-by-displayfusion/?ID=01999ff5-cc0a-70b5-a53d-7c6773d6ba48#43 DisplayFusion I've been lurking on this topic for a little while since I was having the same issue when I played 7 Days to Die. I just wanted to mention that the latest beta version fixed this issue for me. Hopefully it doean't occur again.

Before the fix, I would stutter like CRAZY at 1000 Hz polling rate and I'd have to lower it to the minimum possible to be somewhat playable, but even then it was still there. Now I'm testing on 8000 Hz and haven't had the issue at all.

Didn't add any compatibility hooks or change any settings, just updated. ]]> RE: Severe FPS Drops & Alt+Tab Issues Caused by DisplayFusion https://www.displayfusion.com/Discussions/View/severe-fps-drops-alttab-issues-caused-by-displayfusion/?ID=01999ff5-cc0a-70b5-a53d-7c6773d6ba48#40 Tue, 10 Feb 2026 19:39:29 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/severe-fps-drops-alttab-issues-caused-by-displayfusion/?ID=01999ff5-cc0a-70b5-a53d-7c6773d6ba48#40 DisplayFusion We've released a new beta with some added logging.

Every few minutes there's a big frame hiccup. Only way I've found to resolve this is to disable application hooks globally.

If you add a compatibility rule to disable hooking the application and reboot, does the issue persist?


Apparently the error disappeared when I added Disable Application Hooks in compatibility mode, but I still need to watch, it seems that sometimes there is still a drop in fps, but it quickly returns to normal. At one launch, it was as if this parameter had not been picked up and the fps was still falling. should this setting be done for all games where such a problem appears?

As for the second problem, when it is not possible to switch using alt+tab during the game, I do not know how to reproduce this bug, but now it is not there, sometimes it may appear. ]]> RE: Severe FPS Drops & Alt+Tab Issues Caused by DisplayFusion https://www.displayfusion.com/Discussions/View/severe-fps-drops-alttab-issues-caused-by-displayfusion/?ID=01999ff5-cc0a-70b5-a53d-7c6773d6ba48#34 Thu, 05 Feb 2026 20:44:42 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/severe-fps-drops-alttab-issues-caused-by-displayfusion/?ID=01999ff5-cc0a-70b5-a53d-7c6773d6ba48#34 DisplayFusion If you add a compatibility rule to disable hooking the application and reboot, does the issue persist? ]]> RE: Severe FPS Drops & Alt+Tab Issues Caused by DisplayFusion https://www.displayfusion.com/Discussions/View/severe-fps-drops-alttab-issues-caused-by-displayfusion/?ID=01999ff5-cc0a-70b5-a53d-7c6773d6ba48#33 Thu, 05 Feb 2026 20:15:43 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/severe-fps-drops-alttab-issues-caused-by-displayfusion/?ID=01999ff5-cc0a-70b5-a53d-7c6773d6ba48#33 DisplayFusion

We've released a new beta that should fix this up, please let me know if you still run into issues after updating.

Nothing has changed. I’ve recorded a video demonstrating two bugs I previously mentioned.

The first issue is the FPS drop when Alt+Tabbing frequently. it’s still there, and the frame rate continues to tank.

The second is a very annoying bug where I can’t Alt+Tab out of the game. The windows just flicker for a split second, but the switch doesn't happen. If I hold Alt+Tab and then minimize the game using the Windows key to select another window, the Alt+Tab keys get "stuck" and keep rapidly cycling through all open windows.

I’ve included a key overlay at the bottom center of the screen so you can see exactly when I’m pressing the keys. ]]> RE: Severe FPS Drops & Alt+Tab Issues Caused by DisplayFusion https://www.displayfusion.com/Discussions/View/severe-fps-drops-alttab-issues-caused-by-displayfusion/?ID=01999ff5-cc0a-70b5-a53d-7c6773d6ba48#32 Thu, 05 Feb 2026 18:12:58 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/severe-fps-drops-alttab-issues-caused-by-displayfusion/?ID=01999ff5-cc0a-70b5-a53d-7c6773d6ba48#32 DisplayFusion We've released a new beta that should fix this up, please let me know if you still run into issues after updating. ]]> RE: Severe FPS Drops & Alt+Tab Issues Caused by DisplayFusion https://www.displayfusion.com/Discussions/View/severe-fps-drops-alttab-issues-caused-by-displayfusion/?ID=01999ff5-cc0a-70b5-a53d-7c6773d6ba48#31 Thu, 05 Feb 2026 06:32:50 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/severe-fps-drops-alttab-issues-caused-by-displayfusion/?ID=01999ff5-cc0a-70b5-a53d-7c6773d6ba48#31 DisplayFusion

Am getting the same issue in Highguard. No alt+tab needed, but it certainly makes it worse
My own testing has deduced it is involving mouse polling rate a possibly it spiking the CPU. Lowering mine from 1000 to 250 makes the stuttering less, and tiny/slow movements only lightly hit the frames. At 1000 its unplayable from first boot, but once DP is closed, flawless
