Question / Help 1080p60fps Twitch Help.

[ShadyShroomz]

I have 2 computers, a gaming and streaming. The streaming PC has an i72600k @ 4.5GHz (running at 70 C full load). I try streaming at 1080p60fps and there is tons of lag. Only 2 or 3 frames a second show up on stream. In the OBS window, I can see it perfectly. I've seen other streamers do 1080p60fps on one computer (sodapoppin, and I'm sure many others do it as well). How do I stream like this. My CPU usage is at 30% when streaming 720p60fps, and 60% when doing 1080p60fps (although it's more like 5fps when watching it back on twitch). Any help would be greatly appreciated. Thanks :)

I cannot use the other OBS, as my setup requires me to have multiple audio inputs, but that isn't the problem either.


edit: Just double checked. I still have the same problem on the "regular obs", and I wanted to add, I'm streaming at 3500 bit rate.

Are you using FFmpeg output and streaming at the same time? I noticed that you have the custom FFmpeg output in use while streaming. If you do you'll be using multiple separate encoders at once, it'll probably eat up all your CPU, especially at 1080p 60fps. If you want to record and stream at the same time I'd really recommend using normal recording rather than FFmpeg, and set the recording output to use the stream encoder. That way they'll both share the same encoder and it won't incur extra CPU usage.

Also, note that you're doing 1080p 60fps on previous gen architecture, with only 4 physical cores. Streamers like sodapoppin/lirik/destiny have the new 8 core PCs to be able to do 1080p 60fps with lower presets.

When using advanced output, always use the stream encoder for recording if you want to reduce CPU usage as well. Spawning extra encoders will multiply the CPU usage.

Thanks for the rely! I will try doing what you said. I know sips (http://twitch.tv/sips_) uses a 6 core 3rd gen CPU for gaming and streaming on the same pc and does 1080p60fps GTA V. So I assumed 4 cores would be enough for a dedicated one. How big of a performance difference is there between the gens?

 

[ShadyShroomz]

Changing that did fix it. Will there be a way to record lossless like there is in legacy obs with multiplatform?

 

[Lain]

You can record lossless with FFmpeg output, and it'll actually use very little additional CPU, but the biggest problem with the FFmpeg lossless codecs is that they'll eat up smaller hard drives instantly. Unless you have a multi-terabyte hard drive as with many terabytes free as possible, I wouldn't recommend doing it for long-duration streams.

If you're *just* recording, you can get very high quality streams by just using x264 with certain settings. But if you're recording while streaming at the same time, then unless you have a hard drive with terabytes free as described above, the most ideal way is to make recording share the stream encoder.

Later on we'll have NVenc and quicksync, which will give you more options for recording at high quality while streaming at lower quality without impact.

 

[ShadyShroomz]

I actually do have a 10TB RAID10 nas setup :P

 

[ShadyShroomz]

Could you tell me which container format/video and audio encoder would make it lossless?

 

[Lain]

Oh well in that case you'd want to use AVI container (with .avi file entered), then the huffyuv video encoder, and probably opus audio encoding with a high bitrate, or FLAC if you must have lossless audio (though not sure about its performance in live encoding).

If you're streaming at the same time, don't set OBS to RGB output, use NV12 in advanced.
