Intermittent bad performances, lag and stutter since upgrading to 9.6.1

Hello,

I had zero issues with the previous version and since upgrading I'll have random lag spikes. Also snapping windows in my split monitor setup is very laggy every time.

Is is possible to download the previous version of displayfusion somewhere?

Sorry to hear that! Before downgrading, could you send us a debug log?

  • On the DisplayFusion Settings > Troubleshooting tab, change the Logging drop-down to "L1: Log Minimal" and click Apply
  • 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

After grabbing the log, feel free to try one of these out:

DisplayFusion 9.6.0
DisplayFusion 9.5.0

Hello,
I have to agree with the oroginal poster.
I've used Display Fusion Pro since V. 7.x without issue (~2014.)
Since the latest version was updated to 9.6.1, both on Win 7Pro and Win 10Pro, I've noticed a drastic change. Switching from a single monitor to multiple monitors now takes as much as 30-40 seconds to complete the process.
I'm hoping that a resolution to this lag will arrive soon in an upcoming patch.
Thanks,
JPC

Here it is, it happened constantly throughtout the log file.

When I snapped a window to a monitor, when I changed the settings for the log file, etc.

So I downgraded to 9.6.0 and I had the same issue. Downgrading to 9.5 however appears to have fixed the issue.

Thanks! Not seeing anything out of the ordinary in the log unfortunately

How has it been since rolling back to 9.5?

It works perfectly with 9.5 but I'm still seeing the same behavior on 9.6.4 and I'm running completly different hardware now.

Could you try the latest 9.7 Beta that we just released today?

Latest beta still unusable on multiple WIN7x64 systems. Every system DF now pegs one core at 100% no matter how many app exclusions. Even on an old CORE2DUO DF will sit and use 50% of the box at idle. Have no way to debug why but only noticed this in this round of betas.

@Colin: We've found the CPU issue in Windows 7, it's different than the Win 10 issue in this thread, but we'll have it fixed up for 9.7 Beta 15

All of a sudden it takes forever for the program to work? Now my screen just went black.

I have also been monitoring performance metrics as of late. Having the latest 9.7.1 version installed, DisplayFusion is constantly stealing 20-30% (!!!) of my Core i9 resources. That is insane and way out of line.
I especially noticed this since my upgrade to 9.7.0 (and later 9.7.1) and finally started looking into stuttering and locks happening here and there. - My DisplayFusion Taskbar is regularly lagging and this is where I see DisplayFusion stealing even 50% of my CPU.

I know finally know why sometimes my Visual Studio, Teams and Outlook run so extremely slow!

Also, I regularly get weird black areas in some apps, incl. Outlook. - I am now 99% sure that this is DisplayFusion messing something up.

I am hoping that these issues may be fixed, but I now realize that I have been suffering under it for quite some time. - This is crucial to improve, as I otherwise may accept lacking a few premium features in favor of alternative better-performing apps, as the perforamnce overhead is affecting not only my productivity but also my electricity bill

Some practical info:
I am running multi-monitor setup with virtual monitors on a Philips 49" 32:9 1440p monitor (2.1, 2.2, 2.3) + laptop monitor (1.1) + an older 1920x1200 24" monitor (3.1).
I am constantly running X Chrome windows distributed across my monitors.
I am constantly having Microsoft Teams open (mainly monitor 2.3).
I am constantly working with Visual Studio 2019 Enterprise (mainly monitor 2.2 with test runner window on monitor 3.1).
I am constantly having Microsoft Outlook open (mainly monitor 1.1).
Spotify normally running (mainly monitor 1.1).
Various other apps on-demand of course

Also, I tried shutting down DisplayFusion, which is definitely noticeable!

Hi Bo,

Could you try out this build and see if there's any difference in CPU usage? https://www.binaryfortress.com/Files/DisplayFusion/DisplayFusionSetup-9.7.1-TEST2b.exe

Thanks!
