Is there a way to stream the gameplay I play on my pc via an external laptop on Twitch via Streamlabs (without Capture Card)?

I use to stream on Twitch Streamlabs Obs everything works great… Only the problem is that the stream takes a lot of power and the frames unfortunately heavily influenced… Now I have a laptop but unfortunately no capture card or other and both (laptop and PC ) So the question above… Does this work without a capture card and if so how?

Without a capture card, this is only possible via network streaming. That means you have to stream the video through the network as uncompressed as possible via OBS, OBS on the second laptop then accesses this stream, does all the rest and then transcodes it for Twitch.

And how does it work?
