That was the cause of my original problem. It turned out that when I read in Settings--Performance--Graphic Adapter, it showed "In Use: Intel(R) UHD Graphics" which was the wrong card. But I was lost here.
Then, thanks to the instructions on your link, the right card appeared: "NVIDIA GeForce RTX 3050".
Still, after a restart, it was pretty jerky. I updated the graphics card driver, restarted the laptop, then it worked flawlessly. What a difference!
I also tried running my copy of the preset from the old computer. I started Recording, used Instant Replay and also a livestream test, all at the same time. CPU peaked at 35-40%. The "Stream" button was steady red, no yellow flashing, just steady red. Finally!
The only strange problem now was that the Camera Input showed a stuttering image for a few seconds which then froze.
The weird thing was that it only did it when I panned the camera, when there was movement in the camera image. When it was still, all worked.
I have the camera connected to a Magwell HDMI to USB3 (Gen 2).
I resetted the input on vmix, but same thing again. I restarted the computer. Same problem.
I tried in another usb port. Same problem. I tried in the third usb port (the laptop has three usb 3 ports). Then it worked without problems. I tried the first port again. No problem. I tried all three usb ports. No problem.
What happened in the beginning? Will it happen again? It feels unstable to dare to have in a live broadcast. It feels like I first have to test it for a longer period of time to be absolutely on the safe side.
The new computer is an ASUS TUF GAMING F15 FX506HE-HN001W
Do I need to update the drivers for the usb ports? What if they already are up to date?
EDIT: I've using the computer and my preset now for many occasions and hours. No problem, very low cpu and gpu percent, it works flawlessly.
Conclusion: Changing card from "Intel(R) UHD Graphics" to the correct "Nvidia GeForce RTX 3050" was the solution.
