Question / Help Stream lag when less than 120fps setting?

Hey guys, I got a strange problem: my stream has horrible lags/frame skipping if the streaming fps is under 120. Anyone know what causes this and what could be the potential fix?

Example: 60fps stream: http://www.twitch.tv/fubary0/b/677005924?t=120m
120fps stream:http://www.twitch.tv/fubary0/b/677765597?t=32m

This is strange because I thought it would happen the other way around?! I just want to stream 30/60fps because streaming 120fps lowers my ingame fps a lot. One thing I discovered is that if I limit fps to 60ingame, 60fps setting is fine, but I want to have steady 244 because I have 120Hz display..?
 
Ah, right. I cannot post the full log of the stream I linked with 60fps, noticed there is lots of this message.

Turn on Aero. It speeds up Window capture greatly, and game capture somewhat. Also, set a proper keyframe interval (of 2) in your Advanced settings.

You don't need to downscale if you're running at 2800kbps, with 720@60fps. Still advised to drop to 720p@30, 2000kbps unless you're a partnered caster. This will result in less stuttering/buffering for your viewers.

Can turn off CFR (not CBR) unless you're going to edit the local-recording version with Sony Vegas. Twitch wants CBR, but doesn't care about CFR.

May want to switch from the High to the Main profile if you're streaming to Twitch, as it's what they're expecting on their end.

May also want to turn off your overlay hook (overwolf, msi afterburner, etc) as it could be causing issues with the capture. Don't appear to be duping or skipping too many frames.
