Force directed graph performance hit

Hi there. I'm having an issue with the force directd graph custom visual. I'm not sure when it changed, but since a few days, the visual has gotten a lot slower. We use it to show networks between users, and have many nodes. The more nodes there are, the slower it gets. You see it in the exam[ple files too. The second tab is smooth, but the rest is kind of... low fps....stuttery. If you add more nodes, you'll find that the performance deteriorates.

I didnt change the visual, but the performance is suddenly a lot worse on both the service and powerBI desktop. Did MS change something on their side that could ruin the performance like that?

Thanks a lot!
