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.


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. ]]> RE: 10.0 is killing PC performance https://www.displayfusion.com/Discussions/View/100-is-killing-pc-performance/?ID=d1ff082c-3066-4cd4-8289-a1219f32795c#20 Sat, 15 Jul 2023 01:27:14 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/100-is-killing-pc-performance/?ID=d1ff082c-3066-4cd4-8289-a1219f32795c#20 DisplayFusion

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?

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. ]]> RE: 10.0 is killing PC performance https://www.displayfusion.com/Discussions/View/100-is-killing-pc-performance/?ID=d1ff082c-3066-4cd4-8289-a1219f32795c#10 Thu, 11 May 2023 13:24:46 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/100-is-killing-pc-performance/?ID=d1ff082c-3066-4cd4-8289-a1219f32795c#10 DisplayFusion If you also add the "Disable DisplayFusion Taskbars" compatibility option, does that make any difference? ]]> RE: 10.0 is killing PC performance https://www.displayfusion.com/Discussions/View/100-is-killing-pc-performance/?ID=d1ff082c-3066-4cd4-8289-a1219f32795c#9 Tue, 09 May 2023 18:50:12 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/100-is-killing-pc-performance/?ID=d1ff082c-3066-4cd4-8289-a1219f32795c#9 DisplayFusion

What game is this happening with?


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. ]]> RE: 10.0 is killing PC performance https://www.displayfusion.com/Discussions/View/100-is-killing-pc-performance/?ID=d1ff082c-3066-4cd4-8289-a1219f32795c#5 Mon, 08 May 2023 19:03:30 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/100-is-killing-pc-performance/?ID=d1ff082c-3066-4cd4-8289-a1219f32795c#5 DisplayFusion 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. ]]> RE: 10.0 is killing PC performance https://www.displayfusion.com/Discussions/View/100-is-killing-pc-performance/?ID=d1ff082c-3066-4cd4-8289-a1219f32795c#4 Mon, 08 May 2023 15:53:08 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/100-is-killing-pc-performance/?ID=d1ff082c-3066-4cd4-8289-a1219f32795c#4 DisplayFusion What game is this happening with? ]]> RE: 10.0 is killing PC performance https://www.displayfusion.com/Discussions/View/100-is-killing-pc-performance/?ID=d1ff082c-3066-4cd4-8289-a1219f32795c#3 Mon, 08 May 2023 07:42:37 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/100-is-killing-pc-performance/?ID=d1ff082c-3066-4cd4-8289-a1219f32795c#3 DisplayFusion Same issue, DF is causing an odd stutter in gaming regardless of the intensity of the game.
