Delay between live camera and 3D.glb

[yrostudio]

Thanks a lot for the hard word ! the tool is amazing !

I'm playing with the facetracking virtual try on.
When i move quickly, I've got a (not so) small delay between the live camera and the movement of the 3D object (i'm using a .glb).

Is there an optimization to done ? could we had a small delay to the camera feed without affecting the tracking ?

also if we are two or more people in front of the camera, the tracking change a lot from one face to another.
is there a way to get something more stable ?

Thanks a lot
