VW2024 terrible lag on second monitor

[Greg Mitchell]

Just upgraded to 2024.  Everything I do, i.e. zooming in and out with the scroll wheel has a 1-2 second delay.  I didn't have this problem on 2023.  It doesn't happen on my laptop screen.

I'm on a Macbook Pro M2 Max running Sonoma 14.1.2

I have tried connecting through my USB doc and directly to HDMI.

 

Any ideas?

I may have stumbled upon a solid work-around.  The problem seems to occur when I have the window maximized (NOT full-screen, window is resized to fill screen).  However, if I shrink the LEFT side of my Vectorworks window so that it's a small distance away from the left edge of my display, everything displays exactly how it should without any lagging.  I have moved my tool pallets to other places on the screen and it didn't seem to make a difference.  As long as I have that gap between the left edge of the Vectorworks window and the left edge of my screen, all is well!  I have tested this with both 2024 and 2025, and I've tried this with multiple display resolutions.  Attached is a screenshot of the window resizing I did.  If I make the left edge any closer to the monitor, it starts to get laggy again.  Hope this helps a few people at least!

@Collin DonohueSeems to have made the lag a little better, but not cured it for me. Thanks.

 

One thing that does seem to work, but it messes up work workflow, is to put VWX on my second monitor and everything else on my primary.

As a follow-up to my own setup, it's not the left side specifically, it's actually happening wherever I have my two displays meeting.  For my setup, I have my laptop set up on the left side and my external on the right, with VW running on the external monitor.  However, if I go into the macOS display arrangement and flip them so that my external is on the left and my laptop on the right, the issue now occurs when the VW window is all the way to the RIGHT side of my display!

@Collin DonohueInteresting. I'll give that a try today. Thanks for clarifying.

Updating to macOS Sequoia solved the problem for me without any window size trickery required.

 

I realize that's not a viable solution for some people, but it has worked well for me and my multi-monitor setup.

Hello,

If you change this setting to have displays as separate spaces does it help?

I just tried this and it made no difference at all. Windowserver is still running at 100%CPU when I have Vectorworks up and running. I've just noticed the post about updating to Sequoia so doing that now. Coudln't work out how to delete this post so will repost once the update us finished.

Good new. I updated to Sequoia and it is much better! I'm full screen on my external monitor and my windowserver is staying around 40%. 

My sanity has been restored.

Updating to macOS 15.1 and setting displays as separate spaces resolved the lag issue in Vectorworks when using a multi-monitor setup with the window at full size.
