Question / Help Stream Buffering

I've been streaming recently and trying to get everything setup right. I thought everything was good but then I had some friends telling me that the stream was buffering quite often. I checked it out myself and sure enough it's buffering a lot.

So, I tested my internet speed to the closest Twitch server which is in Dallas. I've got 115 Mbps // 10 Mbps from Austin to Dallas which is good. Using the estimator on the website I should be able to set my bitrate at 3500 // buffer 3500.

Ok, so Now for my computer specs:
  • Win 7 Ultimate 64-bit
  • Intel Core i7 4770k OC 4.2Ghz
  • Asrock Z87 Extreme6
  • EVGA GeForce GTX760 SuperClocked
  • 16 gb G.Skill Sniper Series DDR3 2133
  • 3x ASUS VS24AH-P 24 in 1920 x 1200
  • 128 gb Samsung SSD 840 Pro
  • Razer Anansi MMO Keyboard
  • Logitech G600 Mouse
So, with this I figure I should be able to stream well enough. Here are my OBS settings.

[Video]
UnlockFPS=0
Gamma=0
Filter=0
BaseHeight=1200
BaseWidth=1920
DisableAero=0
Downscale=1.500000
FPS=60
Monitor=0

[Video Encoding]
QSVPreset=1
QSVUseVideoEncoderSettings=0
CustomQSVSettings=
CustomSettings=
UseCustomSettings=0
UseCFR=1
KeyframeInterval=0
NVENCPreset=Default
X264Profile=high
UseBufferSize=0
PadCBR=1
UseCBR=1
Encoder=x264
Quality=8
Preset=faster
MaxBitrate=2000
BufferSize=2000
​
I'm not recording while streaming and as you can see I've got my bitrate actually set to below the estimated settings that were given. Any help would be appreciated and if there is more info needed I'd be happy to supply it.

Well, the estimator is for streaming in general and to give you starting values to work with. Twitch in special has sometimes problems with higher bitrate streams, especially if you are not partnered and get no transcodes. They officially recommend to stream at around 2000kbit for 720p and to lower the resolution/fps if you have problems of want to increase the quality.

Now, you could do the following, test again with 3500 and make sure twitch saves your broadcast (has to be activated on the twitch page under settings, video) and download the recorded video afterwards. See if it has any hickups, missing frames, etc. Then if everything was fine, test stream with 2000 bitrate and let your viewers comment on the buffering again. If they still buffer, either lower your bitrate even further and see if that helps, or do a test stream to hitbox.tv for example, and let them check the stream there.

In the recent weeks it was mostly a problem with twitch. And unless you drop frames, it very certainly is a twitch problem again. But you can test the mentioned things and show us a log file and we will see.
