Question / Help Jumpy/Laggy Stream, Smooth Gameplay

For some reason my stream is really jumpy...like every 5 sec. or so it lags for a few frames. I'm not dropping hardly any frames according to OBS and my gameplay is still smooth (60+ FPS). It's not just the live stream either, as the recording of the stream also has the jumpy video. I had my bitrate and buffer set at 4000, and I read that for twitch anything over 3-3.5k is too much, so I set them both to 2000 for a test stream. Game graphics are on low, my FPS was a solid 60-80 FPS throughout the stream, although it doesn't show on the stream. Here's the video where you can see some of this lag, especially toward the end of the video: http://www.twitch.tv/dthpwn/b/444496136

Here's the OBS log for that stream:

log looks fine just a little bit of an high frame processing time and at some point you lagged a lot of frames

your vod also has no sound ... at least for me and the weird thing is the actual gaming content was okay just those splitscenes in the game were laggy as fuck

Ok well the scenes at the start are supposed to be 'bad' and have little/no motion in them. The part I noticed it most was at the end when I was running. You can watch some of my other recent streams for more examples (L4D2). Any suggestions?

EDIT: if it matters, I'm running an AMD Phenom II 965 oc'd to 4GHz and a Radeon HD 7770 oc'd to 1100 MHz core/1175 MHz memory. Should I change my 'very fast' to 'super fast'?

I'm not quite sure why your processing time is so high, your hardware is superior to mine but your frame processing time is far, far higher than mine.

In particular those 2 steps take an awful amount of time. Could you try something? Read my guide and consider following it, step by step. And if you do follow it, step by step, try setting OBS back up at a bare level. What I mean is, just use 1 source, just the game. Using Game Capture if at all possible (just run the game in a Borderless Window/Fullscreen Window). I want to see if we can get that processing time down for you.
