As you can see, vods and livestreams contain terrible stuttering. (Edit: I'm assuming that)it's not a computer issue, as I'm running the game at 60fps constantly with no hiccups.

my upload speed is 2.02mbps, so I set my max bitrate to 1400 and the buffer size to 3500.

my send buffer size is 4096, quality is set as low as I can get it (Zero)
and audio bitrate is 128.

res is 1920x1080 downscaled to 1280x720 and fps is 30
aero is disabled.

Is there something I have wrong? I followed this guide pretty much to the T, tried many things. Can anyone help me out with this, please?

You're dropping a ton of frames, which means you are streaming at too high a bitrate for your connection, or you have a bad connection to the Twitch server you selected. Grab JTVPing from http://www.teamliquid.net/forum/viewmes ... _id=326034 and find the one with the lowest latency and pick that in OBS. If that doesn't fix it, lower your bitrate until the dropped frames stop.

The number of dropped frames went down to 135 from the 6.000 or so it was previously. Thanks so much for dealing with idiots like me!! :lol:
