ArcRotateCamera big mesh, mouse click, Performance issues

Thank you for browsing.

I have an example of a 400 Megabyte grid loaded with assetsManager that performs poorly after clicking。

But using the keyboard control will not have a lag, very smooth。

I hope someone can help me out
set isPickable = false for mesh,After the scene is opened, clicking on the large grid will no longer get stuck. After the scene mouse wheel zooms in, clicking on the large grid will become stuck again

Could you provide a repro in the Playground?

It seems that isPickable=false should fix the problem, even if you zoom in…
