Question / Help Lag Spikes while Stream is on

Hello, I wanted to ask you guys with more experience about a problem I am facing.

When I stream League of Legends I tend to have lagg spikes, nothing that takes more than a single second or 2 but enough to raise the MS(ping) bar on the top for a sec, for those familiar to the game.

Now I already tried to use 900 bitrate up to 1500 bitrate (I have 2 mb Upload)
And of course it gets a lot better at 900, but there is a tendency of lag spikes never the less.

What I find strange is that even when I stream , lets say, at 1300 Bitrakes CBR activates Costum Bitrate Disabled .
I round the flat 90´s ms/ping but get those lagspikes up to 200/300 that just take 1 second or 2.

my question is on how to fix this , I think there is a little thing i need to do to fix it as I imagine I can stream 720p League of Legends with my internet/computer.

Thank you.

///May I ask if the Latency Tuning Factor should be used and/or modified?

Thank you for the answers,
(My computer handles this easily , so the only issue could be on the internet, yet I imagine 2 MB upload should be enough)
 
Unfortunately, 2Mbit may not be enough. But, we'll see...

... could you:
  • Post a log of a session that had these lag spikes?
  • Run an upload test, making sure to pick a server near the one you've been streaming to. Obviously both should be as near to you as possible.

You see, one particular problem you're facing -- you're playing LoL and LoL has a somewhat poorly optimized way of communicating with the Internet. You'd imagine a game that's been out for as long as it has would be more optimized but sadly it's not. It's a bandwidth hog, quite bad too. So, it doesn't really play well with others. ;)

Which is why we need to know your real world upload speed. To push the stream to its limits whilst also letting LoL have its fair share.

Will in a second. Please reply as soon possible as I really wanted to use the weekend as soon as possible to put the stream on air again (yet, now fixed)

THANK YOU FOR YOUR TIME!

1.1 Mbps is really fairly little room to work with. Try the following:
  • Encoding
    • Enable CBR
    • Enable CBR Padding
    • Disable Custom Buffer Size
    • Max Bitrate: 650
  • Video:
    • Resolution Downscale: 480p
    • FPS: 24
 
Is there really the need to downscale everything so much?
The lag I have is minimal, just some spikes, of course in a "last hit" game makes the difference, I though something like the Latency Factor would do the trick.

Going for 480p makes me kind of sad , as I wished for the minimal quality on the stream, being it 720p.

Would you have some time I could provide you the stream , turn it on for a bit and you could see by yourself whats the case we are talking about.
 
As I said, 1.1Mbps is really very little to work with. It's not OBS that is the issue, it's LoL in combination with your Internet connection. The reason I chose 480p is so you could have some room to actually maintain some quality. 480p with the Lanczos filter could potentially actually look better than 720p. On a low bandwidth, that is.

Just try my suggestion and see what you end up with.

I just want to say, THANK YOU!
My stream was an absolute TRAIN WRECK, then I found this. I, quite oddly, have the EXACT same down and up speed as him, and I've had the same problem. Also, while the stream quality isn't the greatest you could say, it's purely my internet, so thank you for saving me on this one!
OBS ROCKS!
