Hi I got this Lag as well. Thought it was a problem that my system update to sonoma was activated, before the release of servicepack 2.
But still got the problem again. I'm Running Vectorworks 2024 on a Macbook pro 14" M1, with Sonoma 14.2.1.
I've got two external monitors connected via HDMI=>USB-C connectors.
I hope you can help in this matter.
kind regards
Marco
