DX11 - no quad on notebook!?!

hi guys! strange problem, perhaps Optimus Card related but I’m not sure…
I was playing with DX11 on my desktp computer. After developed some nice stuff, I copied them in my notebook in order to bring it to the club


Quad (DX11.Layer) was not rendering!
I had to substitute all with Quad (DX11.Geometry) -> Constant (DX11.Effect)

weird, isn’t it?
