I only started using any of the V5 betas in the last few weeks. Running the Dec-1-2023 beta right now, I notice a considerable lag navigating the viewports and the UI in general. The exact same file will feel more sluggisch in V5 compared to V4. I don't know what changed to cause this (perhaps the grouping functionality?). Also, I can hear the fans of my Macbook Pro spin up when working, which it never did on V4.

Any thoughts?
