Question / Help Game lag while streaming

[NewSpleen]

Hi, first i'd like to start with my computer build, it's i5 3570k at 4.3ghz, 16GB of ram, and HD7970 3GB.
When streaming my game performance is horrible, i get stutters and lags
I tried twaking the settings, different resolutions, lowering bitrates but nothing seems to help.
The only way I was able to stream was on 720p, with 1k bitrate and 25fps and even then my game lagged and I could have felt some input lag and stutters. and the result on twitch tv looked horrible (bad quality)
My upload speed is 5mb/s which should be enough, so I guess it's hardware related.
What should I do in order to stream without in-game lag in 720p or 1080p?

Please post a log file so we can see in detail what is going on, here is how -- viewtopic.php?f=5&t=97

Please run an upload test at http://testmy.net/upload -- pick a server near you and do the same in OBS, obviously. To get a more realistic estimate of your upload bandwidth.

12:02:54:

there are a few more btw, but this is the latest one
thanks.

 

[Kharay]

Buffer size: 0? Please reset your OBS and try again.

Start -> Run -> %AppData%\OBS

Empty that folder, without OBS running obviously.

Then start OBS again, it will have reset completely. Set it up again and leave buffer size alone! Just go with a CBR bitrate of, say, 1500 - 2000 at 30 FPS.

 

[NewSpleen]

It's better now, thanks!
but still a bit of impact on game performance, do you think it is my hardware?
1080p, 1500cbr, 30fps.

 

[Kharay]

Could you post a log of your most recent attempt? And what are you streaming?

 

[NewSpleen]

I'm streming battlefield 3, even though the fps is over 100 when streaming i still get some drops and noticable input lag

Note the bold text -- You were lagging 3 frames in that particular session. Given the fact you were recording at 30 FPS at the time, that's 0.1 of a second. I'd hardly call that lag. ;)

I don't really know what else to say -- if BF3 has options to enable or disable hardware input you may want to switch between the 2 and see if that solves the issue. Other than that as far as OBS is concerned the stream is just fine.

Im having 2-3 seconds delay INGAME while the live stream is on... anyone can help me with that !

This is a really old thread, and the issue you're having is unrelated to its subject.

If you're getting high ping, that means your stream and the game are competing too much for your internet connection. First try enabling "Minimize Network Impact" in Broadcast Settings, and if that still doesn't help, try lowering the bit rate that you are streaming at.
