Hmm. It should be smooth (on M1) unless there is a mismatch in refresh rate between the dummy and the display (should be 60Hz). What is your config? Thanks! |

Wow, that's a nice setup. :) However I have no idea why the scrolling is laggy. :( By laggy you mean choppy or is it slow to respond? Does this happen if you mirror a dummy to the internal screen as well? |

Thanks !! :D It is choppy, just looking if other things are also a little choppy and it is. Is there a refresh rate setting from the Dummy Display? Just want to make a ScreenRecord: |

Hi @Zorast - no refresh rate setting, dummy displays are 60Hz. these should match prefectly with the 32" Pro Display XDR. But: to me the scrolling in the video seems to be smooth as silk. Maybe I am not seeing what you see (for example if for some reason the display is set to 30Hz you'll see the video at 30Hz as well even though the dummy is running at 60Hz) |

Hey waydabber, u have to watch the YouTube Video in Full Screen then u will see a a slightly laggy choppy scrolling witch is not there wehen better dummy is closed. So hurl does confirm that on a MacStudio, so that nothing todo with the internal Display i think. |

I saw that you updated the screen recording to a better quality but still could not exactly see the problem on the video. Sorry about that. I'll convert this one into a discussion to see if others have a similar experience! |

I am a brand new new BetterDummy user, am experiencing the same issue with the interface being slightly laggy. It is as if the redraw can not quite keep when I scroll, or drag elements. My setup is a Mac Studio (M1 Max) driving two 32" Pro Display XDRs. I have been driving these same displays using a 2018 Mac mini (!) and two Blackmagic eGPU units, using SwitchResX to achieve 3360 x 1890 @ 60Hz (≈ 120 dpi on the XDR). |

Do u know why the laggy scrolling is not noticeable as far in live when uploaded to YouTube? Can u make a screen record too ? |

Hello Zorast. The lag I am seeing is slight and applies to all UI elements. I think it would be hard to perceive on a YouTube video, even with a high frame rate. In any event, I've not uploaded to YouTube, and don't want to start now. waydabber, I am overall pleased with BetterDummy. If you can perceive the slight lag I'm talking about, maybe you can improve it in future releases. |

Did not see any "more" GPU load when BD is enabled, did also make some test with gaming and did not see any fps differences there. There's only some not smooth visuals. But this problem is new. The first versions of BD does not have this issue for me. |

Hmm. The problem being new is interesting. BD actually does not do much when the virtual screen and mirroring is set up, it is all done by existing functionalities inside macOS and some hardware capabilities of Apple Silicon. It would be educational to try again with some early BD builds and see if the issue is there - as Apple did tweak a lot of things lately in Monterey (including GPU stuff). |

Probably they limit the performance with higher resolutions for better system stability |

Maybe. I just think optimizing for 8K desktop mirroring was not high on the priority list. :) |

Hi there!
I did recognize a laggy not smooth scrolling in all browsers i testet > Safari, Firefox, Chrome.
It is noticeable when u scroll slowly with a TrackPad.
