Whenever I try to stream with 40 - 60 FPS (I can stream with 25, but I haven't tried with 30, 35 yet) obs just stops responding, or more specifically, it just freezes, it doesn't say "Open Broadcaster is not responding" and such. I've tried looking this up at Google but it seems I'm the only on with this problem. :U halp

1080p at first is not going to happen with this cpu especially not with 60 fps also for what reason did you change the scene buffering? from 700 down to 400?

400 was an older defeault a long time ago, he might have installed it a long time back but never used it.

Also, yea, you'll want to use more downscale for that processor. If you only have 900 bitrate to spare for video, I'd recommend 2.0

No, currently 1080p60 is not going to work well under any circumstances, and certainly not with your bitrate limitations. If your maximum available upstream bandwidth is around 1 Mbps you should be targeting a stream resolution closer to 360p or 480p.

But yeah, an i3 isn't going to likely even be able to handle 720p@30, much less 1080 at all, even less at 60fps (very, VERY few systems can run 1080@60, and it tends to cause Twitch's video player to **** the bed anyway, so isn't recommended even with a dual-box casting setup).

You're asking a mouse to pull an oxcart full of cement. It ain't going to work.

The proper way to see how well you can stream is to find something that does work and then gradually increase the settings until things start to go wrong, then back it off a little.

So to start with, go small. 360p resolution. 30 frames per second. Set your preset to Very Fast instead of Slow. Set your audio bitrate down to 128. Turn Constant Frame Rate to On / Yes. Set all your audio devices to 44100 instead of a mix of 44100 and 48000 (including OBS).

Once that's set, stream for five minutes doing the fastest action possible in whatever game you're playing. Look at the log file. When these percentages:

18:02:11: Total frames encoded: 732, total frames duplicated: 641 (87.57%)
18:02:11: Number of frames skipped due to encoder lag: 637 (87.02%)
18:02:11: Total frames rendered: 99, number of late frames: 1 (1.01%) (it's okay for some frames to be late)
Click to expand...

... Are all at 1% or lower, then your stream is ok. If they're very close to 0%, you can increase some settings and test over again. If any of these percentages are still over 1%, then you need to reduce settings more... if you've done what I said and this is the case, try using SuperFast or UltraFast preset. If none of that works, your computer can't run both the game and the stream at the same time.
