NVIDIA Optimus problem with 3ds max on m4600

Hello again!

Recently I've installed Autodesk 3D studio max, but I have some problems with the viewports - it's lagging.. This is a video, which describes the problem very good - http://www.youtube.com/watch?v=09EaaIF-raQ ( it's not mine ). The same problem has one friend of mine with the same m4600 with the same video card - NVIDIA Quadro 1000M. I was browsing the internet for information, but I couldn't fine solution.

I guess it's something from the NVIDIA technology. I changed the global presets in the NVIDIA control panel to 3D App - Visual simulation, but the same.. In the 3DS Max I tried the three available drivers - nitrous, opengl, directx, but it's still laggy. 

And .. I'm sure it's from the video card, because when nvidia drivers is not installed I have no problems with the program.

Thanks in advance.
