Yes, I see what you mean. Indeed on startup of the panel, there are many network syncs and since everything runs on the same simulator thread it will be noticeable. It is nothing we can really improve unfortunately. But it is also clear that when the panel isn’t loading, it has minimal impact.
I know it might not help alot in VR, but there is a keyboard combination Ctrl + N which will toggle the panel visibility without completely shutting and loading it from scratch. If you can somehow reach that in VR it would also make it possible to hide and show then panel with minimal VR fluidness impact.
Kind regards,
