Internal object motion blur doesn't depend on shutter speed

[Wolf3D]

Hi, I've a problem with internal motion blur (organic deformation). The motion blur seems to not respect the shutter speed (examples at 50 and 200 Hz), but it seems to be calculated between the current and the last frame (25 Hz or fps).
Images show the problem. Is there a solution?

Shutter speed: 50 Hz

Shutter speed: 200 Hz

Hm, I'll check this. Could you create a simplified scene showing this?

Yes. I noticed that also the exposure level does not change in the render with this video mode (the only where motion blur works), when I change the shutter speed parameter.
Also I've checked or unchecked the motion blur parametr in camera parameter window, the results don't change.

Vray used: 2.30 installation for maya 2013 - Vray core 2.00.01 - Vray standalone 2.20.01

I've had a strange phenomena when I setted in this example scene a shutter speed at 300 and at 400. In this last mode the mb disappears, also at 340 But now I cannot be able to replicate this...

It just doesn't work with physical camera.
