Building second PC for streaming ( dedicated streaming) - Page 7

post #61 of 96
Thread Starter 
Yes, ofcourse i didnt use such a slow preset on mine PC like Slow, Slowest, or Medium, my PC cant handle it for sure with x264. I tried to stream by using NVENC, it doesnt have that much options and doesnt affect almost at all in terms of cpu and gpu load, even the best quality preset for NVENC, which as i said near to be equal to x264 - very fast. And cpu load not going higher than 75% and gpu load not going higher than 80% ever. And this is in most cpu and gpu intensive games. This is enough safe room i guess. So current PC performance should be enough for streaming without performance issues. Just want to figure out what is the problem behind this and how to avoid it.
There must be fix for that ...

You're not going to get 100% extra performance with the unlocked i7, but would be paying double the price. Food for thought.

You should be using faster presets. Your hardware isn't good enough for slower presets. I'm assuming most streamers use Fast, Faster, or Fastest. Those are the ones you should be using.

Oups, i forgot to say i looked into i5-8600k. And compared its price to i7-8700k. I just dont like CPU's with locked multyplliers. And it is always hard to sell those after, cause they are not overclockable really. (Using Bclk gives only about 100mhz extra, which is not overclock really, and changing bclk usually gives micro-stuttering. Had lots of experience with that before. Maybe they changed something in new line of cpu-s and mobo-s. But highly doubt about it)

But yea you are right, from comparisons, i5-8400 looks good enough for sure, i will look at it today more smile.gif. I am worried that in all comparisons i saw, between i5-8400 and i7-7700k there were used Ultra/Max and whatever call it - one of the highest graphic presets. Which means that on low preset, which is cpu intensive always, i5-8400 can be a lot worse than i-7700k or i7-8700k , especially against overclocked one.

For now 8400,8600k,8700k are out of stock/ not being sold yet in all shops, except few online-shops. So need to wait a bit to see real prices for them to decide better what will be worth it. Hyper threading enabled compared to disabled lowers cpu usage by around 30% or even more. Which can give some additional time (like a year - 2 yaers) to being able to play in games without cpu loaded close to 100%. Thats why still think about that i7-8700k. But i5-8400 and i5-8600k looks very good too. Really depends on prices of these models, especially two i5's.

Please use the edit button.

What bitrate are you using, and what all have you changed in the advanced tab when you were testing NVENC encoding? Also I'm assuming you are broadcasting to Twitch.

What do you mean by "use the edit button"?

I tried 720p 60fps 6000k bitrate, it is said 5k is enough for that, but still, to find better quality tried 6k. CBR, Default Preset - said to be the best in terms of quality, Profile - high, Level - 4.1, double coding enabled, B-frames 4 (tried lower values, but this seems to fix stuttering a little bit), Key frames - 2, Base resolution 1080p, Downscaled - 720p, 60 fps, lancsoz filter. Yes you are right, trying to broadcast to Twitch.

I don't think Twitch handles that high of a bitrate. Most streamers I watch use a bitrate between 2000 and 3500 kbps.

It is officially handles up to 6k. Though i tried, it even handles 10k without any issues. Problem is not in twitch service, if you thought about screen tearing. It is already on records on my own pc, which i did for testing aswell. There can be solution around using specific parameters in obs, like steam launch parameters, or maybe to change some of standart settings, dont know exactly bulb.gif

The higher the bitrate, the more difficult it will be to view your stream for the average user. You have to remember quite a few people out there don't have gobs of bandwidth and probably share with other users. I highly recommend optimizing your stream for a bitrate between 2000 and 3500 kbps. It is possible to have a high quality image at this bitrate.

I remember all of this, thanks smile.gif. And i will use x264 and lower bitrate, etc. My goal right now is to find how to fix very visible stuttering on the stream, because it will not matter about my bitrate, resolution and so on, if those awful stutters will be on stream. I would personally not bother myself to watch such a stream, doesnt matter it is 6k or 2k bitrate, 60 or 30 fps, 1080 or 540. It is just unacceptable in any form.

Got a couple things to respond to here.

1. The edit button is at the bottom left of your post. Use that instead of replying 3 times in a row. The system might accidentally flag your posts as spam and automatically remove them and prevent you from posting without warning.
2. I cannot find some of the options you are pointing out. Are you using OBS? I believe you said you are.
3. Twitch now allows for higher bitrate. As a part of them welcoming more people to broadcast in 1080p60, they removed their 3500kb/s limit, and suggest 6000kb/s for this setting.
4. What internet speed do you have? Have you tried a proper speed test? (Don't use speedtest.net, use something like Battle For The Net)

Yea i use edit button, i thought you mean something else. Somehow i made excess post.
By saying options i mean launch parameters of obs.exe file. if some exist at all.
Problem is not in internet or twitch. I have no packet loss. Stable 100mbit /100mbit - upload / download. No problem with internet speed connection. About bitrate usage i mentioned in previous posts.
Stutters were even in stream records, which were recorded localy, on my own pc.
