On a laptop with NVidia Optimus, there a several methods to get an OpenGL application to default to the discrete GPU, rather than the Intel integrated GPU. The easiest method is to export NvOptimusEnablement from your app (http://developer.download.nvidia.com/devzone/devcenter/gamegraphics/files/OptimusRenderingPolicies.pdf).
Is there any way to do this with an AMD GPU, other than through the Catalyst profile? If not, where can a company request support for their application's profile in the Catalyst driver? (the app is a commercial Solid Modelling/CAD package)
Hi,
you can use:
extern "C"
{
__declspec(dllexport) int AmdPowerXpressRequestHighPerformance = 1;
}
This will select the high performance GPU as long as no profile exists that assigns the application to another GPU.
Please make sure to use a 13.35 or newer driver. Older drivers do not support this.
