First of all, thank you very much for your reply.
Your response takes me a step in the right direction: now at least I know where to start.
For some reason, this computer came with two video cards, one Intel(R) HD Graphics 630 for everyday non-demanding use, and an NVIDIA Quadro P5000 for gaming and more demanding tasks.
Usually, when I launch an application or game, windows switches seamlessly between the two as needed, or, I can go to my Display Settings and force select one of the two. I have selected my NVIDIA Quadro P5000 for StarControl_DX11.exe.
Another thing I can usually do is go to my Device Manager and disable the Intel card so I that the NVIDIA one is used for everything.
I have done both of the aforementioned, so the game shouldn't even be detecting the intel card.
Hope this helps. I am grateful for any advice you can give.
Best regards,
