Question / Help FPS spikes and above avg pings.

[Bodegaz]

I am trying to stream League of Legends.

When I dont have OBS on and I am not streaming, I get FPS around 200. My ping is usually around 40ms.

When I have it on, my fps spikes from 20-80 and its very difficult to play because its always freezing/jerking. My ping also spikes around 80-400ms.

I got my friend to check out my stream and he said that the stream ran pretty smooth in 1080P.

I have tried:
Running LoL and OBS on different cores (LoL on CPU 0, 1, and 2; OBS on CPU 3)
Lowering in game graphics (Resolution and quality)
Not watching my own stream, turning off everything except OBS and the game.

I ran the speed test for 33MB of data and my Upload speed is 2 MBps.

This is my OBS log.

The biggest issue I am seeing is that you're using Monitor Capture. There are other approaches to capturing LoL effectively that do not require monitor capture. Use a scene switcher -- viewtopic.php?f=11&t=1785 -- to set up 2 scenes, one for its menu/main window and one for its game window.

 

[Bodegaz]

I have tried using scene switcher, creating 2 scenes. It is still exactly the same.

try streaming at 720p@60 instead of 1080p@60 will change a lot performance issues with an i5 while streaming

I hadn't even noticed the 60 FPS. :P

Yes, 1080p@60 FPS is quite taxing on an i5. Although it can still be done. I have little issue doing it but it requires some tweaking to OBS and to the game in question. But, it's a bandwidth hog anyhow, 1080p@60 FPS. Running it at 30 FPS (while streaming CBR) will actually improve the overall quality of the stream quite a bit.

I ran the speed test for 33MB of data and my Upload speed is 2 MBps.

19:38:33: Audio Encoding: AAC
19:38:33: bitrate: 128

19:38:33: max bitrate: 2107
19:38:33: buffer size: 2107
19:38:33: quality: 8

(is that MBps or Mbps? testmy.net displays the results in Mbps or Kbps)
You already solved the ping problem by telling this... Why you stream at higher bitrate than your upload? You said you have 2M upload which is 2000Kbps and you try to stream at 2235Kbps + possible spikes caused by VBR....

You need around 150Kbps for the game to keep the ping down. And if you talk with your friends while gaming that takes another 50-100Kbps.

So assuming you talk with your friends you consume at max: 2350Kbps + 150Kbps + 100Kbps = 2600Kbps (stream(including spikes) + Game + VOIP)

2000Kbps - 2600Kbps = -600 You ran out of bandwidth here...
