I have made the required selection, but it is still using integrated graphics over dedicated graphics. See pictures. I have the tick box also checked in Pic4D
Thank you for the screenshot. I see that you selected the 3D App-Game Development as Global presets.
Try this guide to switch it to the dedicated one for a specific software. Can you please have a look? How to manually set a default graphics card: Nvidia or AMD
I hope this helps.
