I am trying to stream to twitch and my viewers keep on getting buffering issues when they watch..

Have tried to lower the bitrate and changing servers but seems like its not helping. I am not getting dropped frames and when I try to analyze the log it just says

Possible slow server

The server you are streaming to (rtmp://live-arn.twitch.tv/app) took 936 ms to connect. This may mean your connection or the server is slow, or the server is far away from you. If you are using twitch.tv, you may want to try using JTVPing to find an optimal server.

1 issues found (0 major, 1 minor).

I am guessing that´s not the issue so here comes the log as well..

11:00:54: No Intel graphics adapter visible in QSVHelper.exe, Optimus problem?

Have tried bitrate from 2000 up to 3500 but seems to make no difference.

Hmm, seems like most of it comes from the cpu, I changed so CS only uses 3 of the 4 cores I got and it got a bit better.

Can´t run a higher then 2000 bitrate though sadly..

I seem to be able to have a higher quality stream when streaming to hitbox.tv, is there an issue with twitch or do they have some sort of limitations on non partnered streamers?
