Bug Report Slowed Game Response when Streaming

[Maldarrien]

Hello,

I'm trying to help a friend of mine get set up with OBS. Like me, he's switching from XSplit. Unlike me, he's running into a game performance issue when running OBS that he wasn't getting before in XSplit.

We've tried changing the audio and video settings to mirror what he's been using in XSplit, but that hasn't made any difference.

He's streaming StarCraft 2, and when he streams with OBS, he'll click in-game with his mouse, and it'll take a moment or two for the game to respond. This sounds like typical lag, and his internet speeds are pretty low. He's in Denmark, and apparently cannot get faster internet speeds.

The audio quality in OBS has been really fantastic compared to XSplit. It makes me think that we're sending more audio information with OBS than XSplit, which may be taxing his low internet speed. We've tried using AAC with 64bit down from 128, but that didn't seem to make any difference.

We are using the Game Capture plugin. Any advice or tips for improving the in-game performance when using OBS would be appreciated.

Can you get a log from his stream please?

 

[Maldarrien]

Yes, I'll get a log from him. It'll be just a few minutes.

He's using a really old version of the app. He might want to upgrade to the latest version and try again before reporting a problem

 

[Maldarrien]

I had him download the latest version, install it, and try it, and he's getting the same problems he had before.

 

[Lain]

Ah, okay, just had to check, sorry for the trouble. Okay, there are a few suggestions I know of. I know that game lag is an issue for people with lower internet connection speeds. It really sucks actually, because streaming can be very demanding.

Try lowering the quality balance. Lowering it can cause it to be a little less pushy on the bandwidth, prevent spiking. If that doesn't work, then try CBR in advanced. This changes the way data is sent, but can reduce quality in certain ways. CBR makes the transmission a little more stable and I have heard reports that it helps for lower internet connection speeds.

The only other suggestion would be to just lower the bitrate in general to make more space for the game bandwidth. Wish I had more suggestions to offer
