3D How to force my app to use NVIDIA/AMD GPU

Recommended Posts


We sell presentation app which uses Direct3D 9. It works slow on laptops with dual video cards (Intel + NVIDIA or AMD). We have to ask users to manually choose NVIDIA video card for our app.

Is there any API to automatically select dedicated NVIDIA/AMD video card in our app on Windows 10?
