I tried to move the camera in every ways (on the viewport, with keyframes, with the camera node parameters...) but nothings change. I also tried to close the viewport scene and move the camera with the parameter, but nothing.
I did a video recording of my screen to show you what happen on my workstation with the IPR in houdini.

As i wrote, I use, in the same workstation, octane for cinema 4d and works fine, so I think is not a problem of hardware, drivers or windows settings.
