Lag during switching from Rhino to Revit window

What could be the reason for the lag that occurs when switching from Rhino to Revit? Have you had a similar problem? For some tasks, these few seconds of lag can be irritating, because it translates into hundreds of such lags per day. I experience this in different versions of Revit, on different occasions, but I have not yet been able to diagnose exactly when and why.

Hi Jakub,

We need to look at both Revit and Rhino plugins for a conflict. Lets start Rhino on its own and disable these Plugins that do not ship with Rhino. Close Rhino then open up RiR.

The other side of this can be handled with Revit 2025’s addin manager.
