Difficult Streaming with High Endish PC

TranspoLord · Aug 30, 2018

So, I recently upgraded my PC and it's more than capable of 1080p streaming, or at least it should be. I've played a few games and streamed them and everything was running fine. Now, the bitrate keeps dropping way lower than it should

CPU: i7 - 8086k 6c/12t
GPU: GTX 1060 6gb
RAM: 16 GB DDR4 2500mhz
MoBo: MSi Z370 Pro

The game and OS runs on SSDs (OS has one to itself)
I am using XSplit Boradcaster which has worked well for me in the past.
The CPU is not thermal throttling, cause even at load it stays around 45C maxing at 51C
My internet speed is 90mbps Down and 8mbps Up. No other applications are using the internet other than the streaming software, the game, and spotify. Not many should matter because everything else is downloading rather than uploading. I was able to max the stream out at 2750 yesterday, tonight it doesnt even wanna go above 1600

EDIT: I even tried to go to 720, but its even dropping frames then. I should have more than enough speed to even upload that

8Mb up is only good for roughly 4000 stream bitrate and not recommended for 1080p. Playing at 1080p shouldn't be a problem, but you should stick to 720p stream res. The max stream bitrate for both YouTube and Twitch is 6000, but you don't have the upload speed to support it. There are lot of streamers with even 20Mb or more upload speed that limit stream res to 720p.

Also, your PC could have been better speced for gaming/streaming. You have a pretty expensive CPU that has barely more turbo speed than the 8700k. Quite honestly I'd have speced a 8600k to afford a better GPU. Even a 8700k would have afforded all but $15 of what's needed to step up to a 1070.

There is still only so much traffic that can fit through your line,downloading severely impacts your upload unless you have some sort of QoS enabled router or mobo that will try it's best to give priority to your upload.

We're using an extremely overkill solution to networking for the internet we have at my house. Besides, I WAS able to go at a constant 2750 the other day with no problem

Frag Maniac :

The 8086k was free, so I took it. The GPU is what I had before I got the cpu.
and the other day I was streaming 1080p at 30 fps perfectly fine. and this still doesnt explain why its suddenly struggling to go above 1600, even though I DO have the upload speed for it

TranspoLord :

If you can get a log from it and upload it here then someone with enough knowledge on networks will be able to tell you more.

you looking for something like this?

TranspoLord :

The definition of "perfectly fine" is always relative to the user's perspective. The fact remains, you have nowhere near the upload speed to maintain anywhere near max streaming bitrate. For that reason alone you should realize compromises have to be made. Stream buffers always fluctuate too. Just because it seems fine sometimes at 1080p doesn't mean it's always going to be. You have to adjust to an overall average.

Frag Maniac :

Fine. I just dont get it though. Ive done it many times before with slower pc hardware and internet. the bitrate just does not wanna go to 2000 now

Maybe try OBS, it has a higher learning curve, but once you get the hang of it, goes pretty well. Plus it works well with ShadowPlay. There are many good YouTube guides on how to set it up for streaming.

I have, and its no different

TranspoLord :

What did you set the stream bitrate to? Also, have you used an ISP speedtest tool to measure your actual upload speed at various times to see if it fluctuates? And do you have a VPN enabled? VPNs will always slow your net speed.

Lastly, this could have something to do with shared bandwidth if you're on a cable modem. ISP speeds can fluctuate at times, and as mentioned above, fluctuations in DL speed can also affect upload speeds.

TranspoLord · Aug 31, 2018

Frag Maniac :

Ive tested bitrates all the way from 2000 to even 4000. mixing res's along the way. and yes, ive done multiple speedtests and no fluctuation. No VPN. Spectrum uses fibre optic cables and changes it to Ethernet through a device in our house. But that hasnt been a problem before. the only thign that has changed since the stream was good, was better hardware and an upgrade in speeds on spectrum's side. (they did this automatically, we did nothing to get hgiehr speeds)

Frag Maniac · Aug 31, 2018

TranspoLord :

What hardware was upgraded, and have you ran more speedtests (both up and down) since your ISP upped your speed?

We just had another person make a thread saying his DL speed stayed at 75Mb when his ISP upped it to 100Mb. He finally got a hold of one of their techs whom made some necessary adjustments, and now it's at 100Mb.

At least you know what bitrate to limit yourself to though, many people over shoot that one. Seems to me if everything checks out you ought to be able to use 4000 if your upload is consistently 8Mb.

Motherboard, RAM, CPU. and i upgraded it like, a week ago. and yes, i have been. Ive been doing it constantly today! It usually stays around 80-90 mbps

Frag Maniac · Aug 31, 2018

TranspoLord :

For streaming you mainly want to look at upload speed and consistency. How's that? Is it 8Mb every test, and do you test at various times of day?

Also, since you just replaced the MB, make sure you are running the latest network driver for it. The last LAN driver for that MB shows as being released 5/16/18 on MSI's page for it.

(dont mind this reply lol)

Frag Maniac :

it stays around 7-8 each time. and yes, Ive updated the driver for it as well to see if that was the issue. and yes i do it various times of the day.
