Question / Help FPS Drop In-game

[TJmoon]

I play League of Legends and streamed using xSplit. I am trying to switch to OBS but I have one tiny problem and I can't seem to fix it no matter what I change in the settings. I drop and lose FPS when I am using OBS while streaming. I consistently have 60 FPS in game with or without streaming when I use xSplit. However, When I stream with OBS I drop half of my FPS and my frames drop down to 30.

If I had to guess, you're using Monitor Capture with Aero enabled. Make sure it's disabled if you're using monitor capture, otherwise it'll be quite laggy.

 

[TJmoon]

But I have Aero disabled.

 

[Warchamp7]

The log you posted doesn't really show any problems, are you sure it's from a stream that was lagging for you?

 

[TJmoon]

I turn on my stream and its fine for like 5 seconds but as soon as the stream comes online on Own.3D.tv, I just get a huge lag spike

 

[TJmoon]

Actually I think I figured out the problem. Its whenever I stream and I have my Stream up at the same time I start having lags.

 

[Krazy]

Ah, yeah. It is not recommended to watch your stream while streaming. You can thank Flash for being awesome *eyeroll*

 

[TJmoon]

LOL Well Thank you for your help.
