I've got instancing working in my desktop but when i try it with my laptop it doesn't work. As far as i know i should have graphics card which supports shader version 3 and my graphics card supports it. Also instancing example in directx sdk works. And another strange thing is when i debug with pix in my desktop instancing doesn't work. Both in my laptop and pix on desktop doesn't give any error just doesn't draw objects that are using instancing. So is there any other reason than shader version for instancing to be not working. Thanks.
