Question / Help Starting streamer OBS

Hello,

Lets start by a small introduction.
Recently I have discovered the art of streaming. It first started with watching other "pro" players stream the game League of Legends. I decided to take a look at the world of streaming myself. Firstly I googled free streaming software which gave me the link to FFsplit. Most people already know this software, its a great program but not very CPU sufficient. I started watching more streams and then I came across a streamer which HIGHLY recommended OBS.

The program is great on itself and is very CPU efficient.
Despite all this I do have some minor issues regarding the stream I'm posting on twitch.tv.
Sometimes when there is alot of action I notice a fluctuation on my stream, which gives a small to large "freeze" spike.
The entire stream stops responding and continues after 3-5 secconds.

I have played around with the program for nearly a week and I'm still not able to figure out what it is.
Currently I'm using the setup below, this setup gives "almost" no freezes. The question is, do you see something which is off or should be changed to enhance the speed of the stream? The moments the stream "freeze" is when the green square at the bottom of the OBS program turns yellow. Is it my connection, because I am on a 100mbit line and this should not be the issue.

Well, hmm. Everything seems to be in order. I do have one recommendation to increase performance though; If you're using window capture for the main LoL game window, I would actually recommend having aero on (and using the window aero theme). It actually causes the capture to use hardware acceleration which can increase performance quite a bit, though I don't know if that's your problem specifically. Also, you appear to have two window captures active. That might also be contributing to the problem. From your preprocessing time, it seems that these two things are the biggest factors, though I couldn't say for sure.

Other than that everything else checks out.

Jim,

I have been going through some older logs from my OBS client. It seems when i turn the X264 CPU feature to "Faster" the frame drops are like 0.04% all of a sudden, I guess the CPU is giving out on me?
Currently I'm trying the game capture aswel. To see if this will help. I will keep you posted.

Off the record, going to try Version 0.473b to see if everything works smoothly with that 1 ;).
Thanks for the help. Ill keep you posted.

Okay Jim,

Hereby an update.
Currently using the following setup, this is causing almost no frame drops nor does it create freeze on the stream.
