Okay this is likely related to the taskbar polling then, it's really odd that we can't reproduce it here though. I'll pass this to our developers and keep you posted when we have anything further.

Thanks!

I've experienced this as well but haven't narrowed it down to DisplayFusion specifically. Is a fix in the works?

No unfortunately it's the same, getting rid of the taskbars entirely or closing displayfusion seems to be the only fixes so far.

Interesting, if you disable tray icons (right click an empty spot on the taskbar and head to Multi-Monitor Taskbar > System Tray Icons > Disabled) on all your DisplayFusion taskbars, does that fix it up?

Yes the problem appears to be fixed with the taskbars disabled even with displayfusion open.

It reappears immediately after enabling the taskbars again.

This issue does not appear limited to Slay the Spire 2, after disabling the taskbars I've noticed notably more consistent performance in every game I have installed, especially when moving around a cursor which in some games is very very typical like path of exile.

Weird, what if you disable your taskbars entirely?

I've disabled all 3 hooks in the advanced settings and the problem still occurs.

If I exit display fusion completely the issue goes away.

We tested it here but can't seem to reproduce it. If you disable all 3 hooks globally in the Advanced Settings, does that fix it up?

We'll do some testing here and keep you posted on what we find.

Thanks!

I can confirm it persists.

When I'm not moving my cursor around I easily reach my capped FPS but as soon as I move the cursor it beings to stutter and goes down to half with lots of fluctuation.

Can you try out our latest beta and let me know if the issue persists?

Here you go, hopefully you guys can figure it out!

The game I've been having the issue with as of late is Slay the Spire 2 but it definitely happens in many games I play to the point that sometimes I just close display fusion while playing stuff.

I've disabled hooks for every single game on my desktop with

Code

Select All

C:\Program Files (x86)\Steam\*

and display fusion still seems to cause horrible lag in many of them.

Yeah some games don't like when we hook into them. Did you disable the hooks for just that game via the compatibility tab, or globally through the advanced settings?

I had the same issue with Division 2. Disabling Application Hooks in Compatability as you suggested DID work.

I had the same findings as OP. it took me months to realize the problem was displayfusion. I used the compat settings to disable everything since I don't use DF for any of that. Maybe there should be some warning or something, considering it is on sold on Steam

Agreed. It took me ages to realize it was DF as well. To the point of doing a boot drive format, installing software then testing a game before creating a restore point and installing another piece of software, one by one.

Hey guys, been working on this issue for a long time now and just figured out that display fusion was the issue. When moving my mouse in games I will get extreme stutters/fps drops caused by display fusion eating up the CPU. The higher the polling rate on the mouse, the worse this stuttering becomes. At 500hz, the issue is almost fixed, anything above 1000hz it becomes unplayable. I've heard that disabling application hooks fixes the issue, but that disables the main reason I use display fusion.
