Hi, I just built a new PC:
AMD II Phenom 3.4 quad core, 8 gb DDR3 gam, and Radeon 7850 HD for specs.

This is my internet, sometimes it fluctuates but this is the peak.

This is an example of my stream: http://www.twitch.tv/naerok_dt/b/340264862
I know it's long, so skip around, such as around 21:06-22it jumps a bit and freezes, or basically where there are multiple "engagements" of units.

My quality is set as "7", max bitrate/buffer is at: 20,000, broadcast server @ Chicago, IL, vbvmaxbitrate=20000, and my resolution is 1440x900, trying to have a smooth stream @ 30 FPS, I know it's possible and it's merely messing with settings, but any help is appreciated.

I am also using dxtory.

ah, you're dropping a ton of frames, that's why you're getting stream abnormalities. your bitrate is.. 10000\10000? that's pretty high. you don't want to set it more than 5k usually because viewers often have bandwidth limitations.

oh, by the way, try out my game capture as a faster alternative for dxtory - viewtopic.php?f=7&t=283

nope -- just make sure to watch for dropped frames. if you continue to get dropped frames, try turning down your bitrate a little bit more until you stay completely green.
