Question / Help Issues when League of Legends and OBS - streaming

[Wisgurd]

Hello,

I am streaming with OBS to my twitch account. Everything works fine with several games.

The only trouble I have is with League of Legends. Let me explain the issue:

1) I have ping issues within LOL. The ingame ping display shows me a sequence like this
100ms, 95ms, 88ms, 78ms, 70ms, 65ms
101ms, 94ms, 87ms, 77ms, 72ms, 67ms
102ms, .... etc.

It's like having a maximum ping and then reducing to a minimum ping by some steps and then go to the maximum in one step.

BTW: The usual LOL ping (without OBS) is stable at around 30ms. In the past I had a stable ping with OBS running like 45ms.

2) OBS switches every second the bitrate from something like: 2200kbit, 3900kbit, 2221kbit, 3898kbit ....

My installation:
WAN: 100mbit Download, 6mbit upload
PC: CPU 4670K, 16GB RAM, Nvidia GTX770

OBS Settings: (I tried several settings, but none works appropriate)
Video constant CBR, 3000kbit, CBR padding, buffersize 30000
Audio AAC 160
Resolution 1680*1050 (no downscale), FPS 30
Use Multithread, prio normal, x264 veryfast, keyframeint 2, use CFR, x264 keyint=60

Does anyone experience the same problems? Is this bad LOL-code?

If i reduce bitrate to 2500kbit then OBS switches between 1800kbit and 3200kbit. I tried several configuration settings, but always the same issue.

Sorry, I just let OBS run 1 and a half minute with LOL:

Custom Buffer Size: 30,000 ?...

What... in the name... of... something awful were you thinking? How about disabling Custom Buffer Size.

1 -- LoL does not really need a custom buffer size and most decidedly not a 30,000 one.
2 -- (Very) large custom buffers will in fact destabilize the bitrate. Which you are experiencing. ;)

 

[Wisgurd]

Okay, 30000 was one setup I tried. I tried it also with normal buffer.

I tried it again and got the same result. I don't think that OBS is "guilty" but maybe there is a hint one can give.

 

[Kharay]

See, with a default buffer it already was a great deal better. Now, let's find out if you can really maintain that 3000 Kbps to that server.

http://testmy.net/upload -- Make sure to test to a server near the stream server you would prefer to use. To get an idea of what you can maintain to that location.

As i said: with other games i dont have problems

Attachm 1) Speedtest
Attachm 2) OBS log with other game

 

[Kharay]

I did not suggest using SpeedTest.net, I suggested using Testmy.net. Please do that.

You see, the thing is -- LoL is quite a bandwidth hog, its netcode is far from optimal and consequently, you may in fact be trying to maintain a bitrate that is near to your maximum to that particular location. Leaving little to no bandwidth for LoL, causing a high ping.

So, please... no more SpeedTest.net nonsense. Its method of testing is not accurate for streaming purposes.

 

[Wisgurd]

Okay, here is the test. I live in Germany and the nearest server is in netherlands .... not very near.

Your most recent log has a perfect score, essentially. If LoL is still lagging then there isn't whole lot you can do as far as OBS is concerned. No late frames, no duplicate frames, no dropped frames... that's really as good as it gets.

If LoL is still lagging with that score, all you could consider is dropping the bitrate in steps of 50 Kbps until it stops lagging.

 

[Wisgurd]

Thank you very much for your time and knowledge.

This last statement was very clear and supported my understanding that LOL is the beast to beat and not my environment.

Okay, maybe someone reads this thread and calms down it he/she has the same issues.
