I just discovered using your 'Monitor Fading' function to make my secondary display black was giving me random hitches/stutter in 'A Plague Tale Requiem'.

'Monitor Fading' disabled = perfectly smooth, no stutter:

'Monitor Fading' enabled = stutter

Most noticeable at times: 0:11, 0:22, 0:37 and 0:42

This has been driven me crazy for days, but I bet it is also the culprit for the stutter in other games and in video playback I've been suffering for a long time...

WTF guys, how is this possible?? this is totally unacceptable.

How can your software be so untrustworthy and make such a mess for the whole system for such a simple function??

Some people are not sensitive to this kind of microstutter. It is subtle but it's clearly there. Those videos where recorded one immediately after the other, just enabling 'Monitor Fading' with a hotkey.

Ok. I hope it's soon, because DisplayFusion's unability to set a screensaver for only 1 display was what lead me to use 'Monitor fading' in the first place. Now there is no viable option.

So I guess this issue still haven't been touched in the new Beta 18?

I see you fixed it in Beta 21. I just discovered now another problem. When I'm playing a video file in D3D11 fullscreen windowed mode (using PotPlayer and madVR video renderer) enabling 'Monitor Fading' makes the video play switch from 10 bit to 8 bit...


As soon as I disable 'Monitor Fading' it goes back to 10 bit...

I honestly can't fathom why such a simple feature can be so problematic. I resorted to just load a fullscreen black png in an image viewer in the secondary display, and I have none of the problems your 'Monitor Fading' bring up.

Attached are my PotPlayer config (import .reg) and my madVR config (put the file in the madVR folder).
I'm also using LAVfilters ( https://github.com/Nevcairiel/LAVFilters/releases ).
They key is you have to use D3D11 Fullscreen in madVR for 10bit output.

And LAVfilter Video needs to be set to use D3D11 instead of DXVA:

My main display is in a 12bpc Output color depth setting:

and my secondary display in a 8bpc setting:

Right now I'm using a script to load a black.png in ACDsee in the secondary display, which is a cumbersome solution... but it works and doesn't change the video to 8 bit. 🤔

Just gave another try since a really long time without using this feature and... this is *still* happening in 11.0.6 Beta 6.

Stuttering is clearly noticeable in UE5 titles. You can check with this free demo just panning the camera: https://store.steampowered.com/app/2680010/The_First_Berserker_Khazan/

Wow... this explains why i was experiencing so random performance in Delta Force.
I never connected the two.

I'm experiencing the same thing. Stuttering and inconsitent performance in UE5 game when i run DF Monitor fading.

Ryzen 5950X.

Slowly and linearly panning the camera view in an open area should show stutters.

Yes, without quitting the game, as soon as I closed Monitor Fading and went back to the game the panning went back to being smooth.

That made me went back to my old classic solution: loading a full black image in ACDsee fullscreen in the secondary display.
