Intel Arc equivalent for NvOptimusEnablement and AmdPowerXpressRequestHighPerformance?

[levicki]

Software developer here, asking how to force an application to run on dedicated Arc GPU instead on integrated CPU graphics?

AMD and NVIDIA solution is simple:

extern "C"
{
  __declspec(dllexport) unsigned long NvOptimusEnablement = 0x00000001;
  __declspec(dllexport) int AmdPowerXpressRequestHighPerformance = 1;
}

You export these symbols from your executable and you are done.

What are we supposed to do with Intel Arc in order to force dGPU over iGPU?

Hello Ramyer,

Sorry for the late response, I had some health issues.

As I said in my post, other video card vendors (AMD, NVIDIA) provide a software mechanism to mark an application executable file so that Windows operating system executes its graphical operations on a dedicated GPU (i.e. the one inserted into a PCI-Express slot) instead of on a built-in GPU (i.e. the one inside an Intel CPU).

My question was if I have an Intel CPU with integrated graphics and an Arc based video card, how can I mark my application executable so that it uses Arc GPU instead of integrated GPU?

It is a question for Intel software engineers working on Arc GPU drivers for Windows, I don't expect regular support to be able to answer it.
