Yes, I realize it's a terribly high bitrate, but that's the only way I could make the screen look decent... I'm no expert in this, so I'm asking you if there is any way to make the stream watchable with such a motion-full game.. :/

Thanks in advance,

Re: Strange laggs on stream

Wow, there is a lot wrong with your streaming setup. Let's take it one step at a time.

First, don't stream at more than 3500kbps on Twitch. Not only do they not want streamers to do that, but you have to remember that in order to watch a high-bitrate stream, the viewer has to have enough download speed to download at the rate you are uploading. Most people won't be able to watch at 6500kbps stream smoothly, if at all. Not only that, but you are dropping frames, which is usually caused by not a good enough network connection to the streaming server to transmit data at the speed you specified. So 3500kbps should be your max.

So you'll probably notice that your quality will decrease a lot as a result. This is largely because you're using the ultrafast preset. You'll want to change that back to veryfast. The x264 preset defines a set of settings for the encoder to use that affects quality. The "ultrafast" preset skips a lot of extra things that help the stream look good, but the result is that it's easier on your CPU to encode it. There should have been a warning when you changed that setting, telling you not to change it if you don't know what you're doing. This is why.

So if you change your preset to veryfast, you may notice that your CPU usage does way up. So how do you lower it? Well, don't stream at 60fps at 1050p. That is a high resolution and a high frame rate to encode at, which is probably too high for your CPU to handle and the quality you're trying to achieve. Furthermore, Flash is really bad at displaying high-framerate-high-resolution video such as 1050p60, so your viewers will suffer as well. You're going to want to lower your frame rate to 30fps, and maybe even consider downscaling by 1.25x or 1.5x.

Finally, for Twitch, you're going to want to enable both CBR (in Encoding settings) and CFR (in Advanced settings) to follow Twitch's broadcaster requirements. CBR is a requirement, and CFR is useful to make sure that the keyframe interval of 2 is kept strictly, like Twitch wants.

So try all those things and see how it goes.

Re: Strange laggs on stream

Thank you very much for the detailed reply !

Changed everything as you said, here are the results on 1050p: http://www.twitch.tv/supermoler/b/497014627
and on 840 (1.25x) : http://www.twitch.tv/supermoler/b/497016644

My in-game FPS drops from ~60 to ~30 though, so that's an inconvenience. Might just have to hold on until I'll buy new PC or let the viewers "enjoy" 1.25x-1.5x :/

Thanks again for your time and reply

Re: Strange laggs on stream

For what it's worth, the 1.25x stream really didn't look bad. You may need to adjust your expectations of kind of quality is possible when streaming.
