Nvidia Optimus

[Ilohama]

I'm working on a laptop with an Optimus option but when I run Sparky, it still using the intel graphic card and not my Nvidia card....

I found a way to force optimus enabled :

extern "C" {
    _declspec(dllexport) DWORD NvOptimusEnablement = 0x00000001;
}

but i'm not sure it's the best way

You doing this on OpenGL or directx?

It should be the same either way.

DirectX don't print it on consol but yeah, it's the same on both of them xD

That says you can also fix it the following way, but it doesn't mention wich one is the better way.

Static Library Bindings
For any application without an existing application profile, there is a set of libraries
which, when statically linked to a given application executable, will direct the Optimus
driver to render the application using High Performance Graphics. As of Release 302, the
current list of libraries are vcamp110.dll, vcamp110d.dll, nvapi.dll, nvapi64.dll, opencl.dll,
nvcuda.dll, and cudart_._.
