Question / Help Does a capture card help with fps drops/laggy in game feel?

I've been searching this for a while but I can't seem to find many people who use a capture card to stream PC games, only consoles. If my absolute main concern is how the game feels when I'm streaming (and I can't use a 2 PC setup), would a capture card like an Elgato be the best option? Does it offer an improvement over window capture in OBS (CPU is i5 2500k but some games still feel laggy and sluggish in-game).

If anyone uses a capture card to stream PC games, please let me know your experiences.

Thanks

It depends...can you post a log of what is happening right now? Maybe there is something that can be done to reduce the lagging.

Game capture is arguably less resource intensive than a capture card, but they each have their limitations depending on what you are trying to do.

I'm streaming a game called Microvolts and game capture doesn't find it. It's not obs' fault, MV is really terrible program.

Getting a log for you.
