Hi, while compiling some DirectX examples, I have noticed that when using my integrated graphics (Intel HD Graphics 4000) I achieve ~3000fps, however, using my graphics card (NVIDIA GeForce GT 630M), I only achieve ~600fps. I have disabled VSync in the graphics settings. I choose what device runs the application via the context menu in windows. Run with graphics processor -> (device).

This is only with things I compile seemingly. I had the same issue with my previous computers when learning OpenGL. However, if I play any other commercial games, the integrated graphics is far slower as expected. This isn't a problem by any means, but I'd be interested to know why.

Not really sure, but it is an intriguing questions. I'd assume that is a PCIe card? I am wondering if it has to do with the PCIe bus being slower than the integrated graphics, given the latter is closer to the CPU? Just a wild guess.

What would happen if you got a (Intel HD Graphics 4000) as a separate video card and installed it in place of the (NVIDIA GeForce GT 630M)

I wonder if you will get the same performance as the integrated card?
