basically i want to have my pc im using now to game and use a capture card to send video to my laptop but the audio doesnt go through el gato apparently. I need mic and game audio going to my laptop so i can run the stream on that instead of my pc where i would get performance drops if i stream and game on the same one
If you are gaming on the pc it will still need to be handling transmission of data (capture card) to the laptop which in turn could be tasked with streaming.
That extra "layer" of overhead may actually reduce performance on the pc. And that all may be for naught if your network (router, modem, ISP service) are not up to the overall task. All depends on the slowest link.
Suggest that you post your hardware (pc, laptop, network) specs. Details matter.
