Impossible to switch from internal GPU to Geforce 650m

[xellos]

Hi guys
I have a question for you.

I'm trying to play Mario Galaxy 2 in a proper way
I know I have to use the LLE, but the audio is skippy and I think that the music is important to live "the experience" of the game

So I was trying to get good settings for my system:
i7 third gen
internal Intel 4000
Geforce 650m

and in the meanwhile I just noticed that in the graphics menu inside the "adapter" menu, ther's only my Intel 4000!
Even if I've run the game choosing the Geforce (right click on the dolphin.exe file).

well, actually the first time I click the "graphics" menu button, it's says that I'm using the Geforce, but if I re-click it there's the Intel 4000! and it's impossibile to switch to Geforce without closing the Dolphin.

Actually, I think the the dolphin is not using my geforce 650m at all, maybe the problem is the optimus system (and yes, I've putted the dolphin under the geforce menu: start this application with Geforce 650m)

any solution?
is there a way to deactivate the internal graphic?
thank you in advance

Is your nVidia driver up-to-date?

Did you use Directx9 backend ? Not Directx 11
I also assume you're already added Dolphin to "high performance" in Nvidia Control Panel
