I think that you misunderstood my comment.

The video shows how SLI makes the frame pacing more inconsistent, which is a known issue when multiple GPUs work together to solve the same problem.

What I am talking about is more like Nvidia Optimus. This is a common technology on laptops, where the display is connected to the low power iGPU, while games can use the dedicated Nvidia chipset.

I don’t know about potential frame pacing issues on these technologies, and it seems like it was not addressed in the video either. However, I know that newer laptops have a switching chip that connects the display to the dedicated GPU, which, I think, aims on lowering the latency.
