As no profile exists for the game yet, Nvidia's Optimus starts the game in low performance Intel graphics mode. I can manually override this but for those people without the know how the game developers can also instruct the drivers to switch to high performance mode.
All you have to do is add the following lines to your code:
extern "C" {
_declspec(dllexport) DWORD NvOptimusEnablement = 0x00000001;
}
With the newer drivers your game should now automatically run in high performance mode.
