Question / Help FPS drop when Streaming?

[SwiiftYz]

This is my first attempt at streaming with a capable connection and I've hit a problem pretty much instantly. I'm trying to stream Smite or Planetside 2 and have tested both at 720p & 1080p. I'm using an AVERMedia Live Gamer HD C985 which is supposed to take all the stress from my GPU when capturing the video however I seem to be losing between 40-60 frames whenever I attempt to stream. I usually hit 120 on Smite easily, with OBS open and streaming, I struggle to hit 60.

My setup is:
i7 4770k @ 4.4Ghz
2GB GTX 670
16GB DDR3 Corsair Vengeance

I have two 1080p monitors running, one sat on desktop controlling OBS and on my Twitch page, the other playing the game. I'm struggling to play as I normally would because of the huge fps loss I have, is it because of my second monitor idling on the desktop or OBS itself?

Not a cure all fix, but from my experience, my GPU doesn't like having moving objects across multiple monitors while running high FPS games. Try minimizing your twitch and disabling the OBS preview and see if you get better framerate. Also be sure not to stress you CPU too much with the video encoding or you will run into issues as Well.

get rid of the avermedia and just use game capture and stream on your machine.

also make sure that you post a log next time as noted on the stickies if you need help

@qhgf - It was something to do with what window I had opened first, when a game was minimized and relaunched It caused some kind of stuttering.

@alpinlol - Why would I remove the thing taking away all the stress of my GPU? That makes no sense at all.

because in most cases capture cards cause more problems in a single pc setup than anything else.


also theres like 1% gpu usage when streaming so who cares?


also post a log... else noone will really help you

Already posted what the issue was, nothing to do with my capture card considering that's helping me stream.

May I see a log file? https://obsproject.com/forum/threads/problem-make-sure-to-post-a-log-and-or-crash-dump-howto.97/

Game capture will actually perform better than capture cards on more recent video cards. It uses no CPU, and probably uses less GPU depending on the GPU you're using. However, that being said a capture card is still fine. Capture cards are really nice to have sometimes, especially when you don't want to mess with stuff and just capture your screen as-is with no fuss, so there's nothing bad about it either usually. Still has great performance usually, though I'd have to see a log file to know what the problem is in this case.
