I just updated to DF 10.0 and my PC is now almost unusable. Any graphically-intensive program is refreshing significantly more slowly. As soon as I disable DF, performance is restored.

Same issue, DF is causing an odd stutter in gaming regardless of the intensity of the game. Log file attached, thanks.

I have this same issue as well.

Not with games, but with everyday apps such as Microsoft Office, Chrome, etc.

Ever since I upgraded to v10 my Display Fusion task eats about 6-15% CPU usuage at all times. It does not sound like a lot, but my system has been stuttering really bad since the update.

I closed Display Fusion, and my Windows 11 22H2 system is now acting normal/speedy again.

I have the trouble shooting file attached and a screenshot of the CPU usage.

Overwatch 2 with major stutters every 10ish seconds, and Far cry 3 in triple wide down to 50ish fps. Both run a smooth 60 without DF being open.

I have the same problem on almost all the games I play.

Disabling Titlebar Buttons had no effect on Far Cry 3, still frequent stuttering

[QUOTE]@fraXis Could you send me over a debug log? Here are the steps:

• 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

Done. File attached. I also installed Beta 3. Same issue.

I have not been running DisplayFusion for the past couple of days, and my system is operating at normal speed. I started DisplayFusion beta 3 a few moments ago to generate your debug log, and my system slowed down again. The problem is definitely with the latest v10.x version of DisplayFusion. Never had this issue with v9.x or any previous versions.

Installing beta 4. I didn't see any mention in the change notes of this issue being fixed but I will try it out and report back if it's fixed or not.

Well, did the beta 4 resolve your issues? I think DF is impacting my performance and would love to know if this beta resolved?

I have also been having this problem since the 10.0 drop.

A lot screen tearing and FPS drops in all my games even after trying the latest beta (10.1 beta 6) and the titlebar fix.

I've been able to recreate and disable the lag with my League of Legends game client by closing and opening DisplayFusion with a game active so I am confident it is DF causing this problem.

The lag is still happening after attempting this and goes away when closing DF with the game still open.

You said you are getting performance drops in all your games, care to name them?
I'm wondering about DF in this regard too, and looks like the devs have been able to reproduce, but wondered how many game titles you had this issue with?

The most notable ones that I had lag with were:

Battlebit Remastered (even on the "Potato" settings)
Black Desert Online (on the lowest optimal mode)
Insurgency: Sandstorm (also on lowest on all settings)
Leafblower revolution

I thought there might be some more lag relating to mouse pointers being around window edges (like moving the screen in MOBAs and my pointer around in Leafblower), but it seems to affect most, if not all games, noticeably.
