I have no idea. This differs depending on the laptop. I don’t have a laptop with a switchable GPU so I can’t even hazard a guess. It’s becoming a common feature in high-end laptops to have a weak, but power-efficient GPU and a strong but power-hungry one. If that’s the case with your computer (I’m just guessing it is because I see you have drivers for a more powerful GPU installed), there’s got to be some sort of way to switch between them.
I got it all worked out now, getting a solid 50+ FPS all across the board, thanks so much! great game. :)
