TOF short_throw recording FPS not stable

[schetti46]

I'm working on TOF short_throw recordings on Hololens 1. FPS are perfectly stable when TOF detect hand inside FOV (field-of-view) of the sensor. As soon as the hand leave TOF FOV, recording framerate drops to 1FPS automatically.

Here you can see two plot:

On the left, TOF has the same framerate as VLC because hand is inside its FOV.
On the right, TOF automatically drops a lot of frame because hand is not inside its FOV.

I need highest FPS possible on TOF short_throw for my application. Is there some way to have stable framerate on it even without hand inside the FOV through HoloLensForCV?

Thanks!
