Hello,

Im gonna write down my specs first.

Internet: 15mb download/ 1.5mb upload
Modem: Cisco 2100 cable modem, plugged directly into PC
CPU: AMD Athlon II X4 641 quad-core 2.80 GHz
Motherboard: Gigabyte GA-A55M-S2HP
Memory: Kingstone 8GB
Storage: WD 250GB
Video Card: AMD Radeon HD 6670
Monitor: Samsung 27" LED Monitor S27A550H
Webcam: Logitech 9000 Carl Zeiss Tessar 2.0/3.7 2MP

Now I want to start streaming League of Legends, but my ping is too unstable, goes from 40 to 200! I spent two days just trying out OBS and nothing works, only if I really lower down my bitrate to like 650 and CPU preset to slow, but that gives a really bad quality, unwatchable. Everything else higher then that makes my ping rise and I can't play.

My friend has the same internet speed and he can stream just fine, we basically copy/pasted settings in OBS but mine is still lagging with unstable ping. Does anybody knows what can be a problem? Is my PC too bad? Is modem? Or Internet? Please tell what causes this and is there any way I can fix it?

1.5Mb upload isn't sufficient if you want a good-looking stream. You might get away with a drastic downscale but it's never going to look good. The reason you're lagging is because your stream is hogging your upload bandwidth when LoL and other programs need to send their own bits.

Try using the estimator and give the settings it suggests a try: https://obsproject.com/estimator

"Possible slow server

The server you are streaming to (rtmp://live-fra.justin.tv/app) took 930 ms to connect. This may mean your connection or the server is slow, or the server is far away from you. If you are using twitch.tv, you may want to try using JTVPing to find an optimal server. (Already did this)

Slow sources detected

Some of your sources are taking a very long time to start or stop when changing scenes. If you use video devices such as a webcam, capture card, etc, add them as global sources to prevent this.

Bad resolution / FPS / bitrate combination

The combination of settings you are using will likely lead to a low quality stream with artifacting and other problems. Consider either raising your bitrate or lowering your resolution / FPS (qval: 0.033)

3 issues found (2 major, 1 minor).

What resolution are you trying to stream at? If your friend has the same upload speed as you he's either downscaling the resolution or his upload speed is faster than he thinks.

Well I tried many settings but this one kinda of looked the least crappy (until 15 mins in game started lagging and ping went high):
Quality balance: 7
Max Bitrate: 900
Resolution Downscale: 1280x720
Process Priority Class: Normal
Scene Buffering time: 400
x264 CPU Preset: Very Fast
Encoding Profile: Main

My friend is from the same country we use the same IPS and same package I've seen it myself on his speedtest and it's the same. He was helping me with the stream these two days and we tried putting setting exactly as it is for him, but it didn't work. Then we experimented and in the end we solved nothing. The only difference is that he has new modem and way better CPU.

If you're getting high ping, that means your stream and the game are competing too much for your internet connection. First try enabling "Minimize Network Impact" in Broadcast Settings, and if that still doesn't help, try lowering the bit rate that you are streaming at.

I enabled "minimize network impact" but it was still high ping. Finally, I lowered resolution in game (League of Legends) to 1280x720 keeping 1000 max bitrate and buffer size, and it showed some progress. Ping is stable and stream quality is a bit better, although my game is really small on screen and I'm not sure if I can play like that since my original monitor resolution is 1920x1080. If I put my original resolution in game ping gets high and quality low. Is there any way I can and does anybody know what is causing all that ping and low quality? Upload speed is not the problem I am sure of that, it's something else.

Are you streaming over WIFI? How did you get your and your mate upload speed? You can't believe in that shitty speed tests.

I tested it on couple websites and we got it from ISP from our country, it's 1.5 mb upload they didn't fooled me or anything,

This is how my latest test stream looks like: http://www.twitch.tv/fedporo/b/542571583 with ingame resolution 1280x720, and it can't get better then that.

Max Bitrate: 1000
Resolution Downscale: 1280x720
Process Priority Class: Normal
Scene Buffering time: 400
x264 CPU Preset: Very Fast
Encoding Profile: Main

And this is my friend's stream: http://www.twitch.tv/flukkzz/b/541907743 with ingame resolution 1920x1080 and same upload speed and same OBS settings, only that he runs it on 1200 bitrate.

As you can see he has stable ping and I dont. :(

Resolution has nothing to do with ping. If "Minimize network impact" didn't help, then the only solution is to reduce the bit rate until it stops.

And even when ping is okay, if I put 1920x1080 ingame resolution, game will lag and cut. It only runs somewhat smoothly on 1270x720 ingame resolution.
