So I've only found a little bit of information on streaming PC games on a single PC setup, using a capture card as a global source, rather than the OBS screen/game capture. According to the description of this product, it is supposed to take the load off your GPU and CPU with it's built in encoder. Here is a review that does testify to some performance gains using this method vs using screen capture in OBS.

According to this review it does seem to eliminate some of/all that subtle lag when playing & streaming games such as Starcraft (something I frequently stream using OBS screen capture). I also have the 2600K processor (same as the person reviewing the card). So I suppose I should expect to see similar results.

My question is how is this possible? Wouldn't OBS still need to encode the video? From the research I did online it seems you add the capture card as a global source in OBS. From what I gather it doesn't seem to be an encoder option in OBS such as x264 or Nvidia NVENC as seen here:

EDIT: omg... my original thread got cut off half way through after publishing it -.-

I'm going to summarize what I had typed for the sake of my sanity.

How is it possible to see gains when OBS still needs to encode the video using it's x264 encoder when streaming to twitch? Is it because the on board H.246 encoder is making it less cpu intensive by compressing the video before x264 has to encode it?

You can't use AVerMedia's encoder with OBS. But you don't want to...it's pretty bad.

Otherwise, a capture card on a single PC setup will not help you. Game capture and Window capture with Aero enabled are both faster.

Doesn't OBS want Aero disabled to run better or something? What does having it on do?

Nope, keeping Aero enabled makes window capture perform much better. Just don't try to use Monitor capture with Aero enabled...use DWM game capture instead.
