Post a logfile from your most recent streaming session. They're located in %appdata%\OBS\logs and timestamped with your streaming session date/time. That'll give us a lot more information about what's actually going on. Put it between 'code' tags to keep things tidy. :)

Short version: The Monitor Capture you're using is causing lagged frames. Stop it. Your bitrate is also set too high and you're dropping frames. Run the 6MB test at http://testmy.net/upload to find out what you ACTUALLY have available. More explanation down below.

If you're running LoL, you need one scene with a Window Capture for the launcher, and a second one with a Game Capture for the in-game executable (which is separate from the launcher). There's an auto-scene-switcher plugin that will detect the in-game exe starting up and change over, then back when it exits (if you set the Launcher scene as the 'default scene' in the plugin config).


Long version/other stuff:
1) Your bitrate is set MUCH higher than it needs to be, at 4400. Max bitrate should be at 3500kbps; the Twitch servers have issues with accepting more. (I see you fixed that in a later streaming restart, it may still be set too high and need to come down more)
2) You're using Monitor Capture. NEVER use Monitor Capture if you have any other option whatsoever; it's ridiculously super-slow, and causes a crap-ton of lagged frames (which look like stuttering).
3) You do NOT need AAC320; even AAC128 sounds awesome. You're frankly just wasting bitrate there. Drop it to 128. You won't even notice, and you'll have an extra 192kbps to devote to image clarity.


Also, run the 6MB test at http://testmy.net/upload which will give you an idea of the ACTUAL constant throughput you have available; speedtest.net and ISPs rate on 'dead file' transfer rates, which can run far below your rated speed and SPIKE now and then so it averages out over the course of the full file transfer... not useful for livestreaming, or multiplayer game network communication which rely on constant-rate. You'll want to run this a few times at various times of the day, to allow for network fluctuations and congestion.

I went to that website and this is what was found.

Upload :: 8.3 Mbps 1 MB/s


Also, I have been using Game Capture for when I'm in game and switching Monitor capture off/on when I'm entering and exiting game so the viewers could see what I see.

Thanks for the response!
