Question / Help Stuttering Issues

[ProtoApex]

Over the last few days i have been trying to stream dota 2, and I cannot get rid of this stutter. I know my computer and internet are fast enough, but it still persists. Here is the VOD of it on twitch (skip to around half way in): http://www.twitch.tv/tominater12/b/341684052
During streaming CPU usage never went above 85% and core temp never went above 52c. I am also on a wireless connection.

i5 2500k @ 4.2

You are dropping frames, which indicates your bitrate is too high or your connection to Twitch is poor. Use JTVPing to find the best server. You may also want to lower the send buffer to 1460 to reduce burstiness which may be causing this.

You can remove vbvmaxrate=7500 from your advanced settings, it doesn't do anything.

Now what bitrate does my connection support? From the speedtest that is under half what my actual upload is, and the server I was connecting to during this test was the second best with only a 20ms difference. Also the lowest the send buffer can go for me is 4096.

you can just type your desired send buffer into the box.

Ah just noticed you're on wireless, so most likely your bandwidth is very variable due to interference. Just keep lowering your bitrate until it works, or use a wired connection.

It is just a drop down menu for me.

This is what I thought but a few people told me it did not matter. Thanks for the help.
