That has never worked well. It might give high average framerates on paper, but it introduces jitter that produces a worse overall experience. In fact, Gamers Nexus just came out with a video on a better way to measure this, and it touches on showing the problem with multi-GPU setups:

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.
