Hi, I have very bad upload on my internet connection, about 675kbps. So I set my bitrate to 625, same as I have in xsplit. Quality at 6 same as xsplit too. But when I stream I see the bitrate go up to 850 causing massive frame drops, I tried putting the bitrate lower and/or putting the quality lower but I still have this problem. I really like this program but I need to keep using xsplit for now since I don't want dropped frames. Maybe I'm missing something, if so I'm sorry.
Bug Report Bitrate settings not respected

Try to choose the nearest twitch.tv (or whereever are you streaming) server/lowest ping and lower the bitrate to something about 550 - 600. It is set to flusucate about given bitrate, because when you're streaming for example a black screen, it doesn't need that much bitrate. The problem may be your computer not keeping up x264 encoding (it's quite demanding). Have you tried streaming 854x480 @ 30 just to test? What is your processor use when streaming and playing a game? What are your specifications?
I already chose the best twitch server, I stream at 30 fps and a resolution of 768x432, I'll check my CPU use after that but my computer doesn't feel like the problem, I'm only streaming with an emulator. Should I change the buffer size thing, for now I set it to the same as my bitrate. I understand that it fluctuates but the setting is called max bitrate.
Edit: My cpu goes up to 50% when streaming.
Here's my specs:

EDIT
You can also play with Network Send Buffer and see if there's any difference. Could you post a log from streaming?

Thanks for the help btw,

It behaves the same Xsplit does, Xsplit just doesn't show you that live information.
A bitrate and buffer of 600 means you will average 600kbps every second, but depending when the buffer is emptied, you have the potential for a quick spike of up to 1200 for a moment (But again, will average out to 600 across the span of a second) if your network can do it
If you change the send buffer size in advanced, choose one of the choices there. The ones micechal suggested are from a previous version

If you don't want the bitrate to spike, then set the buffer size much lower. This might cause pixelation in high motion scene though.
The max bitrate here is actually the vbv-maxrate of x264, which is the maximum rate to fill the buffer before the frame gets decoded.
