Before the game starts, i have normal ping ( arround 20 ms ) but when we start to fight, ping gets 250ms+ So i would like to know whats my problem and how to play and stream normal w/o lagging ingame. Im streaming with OBS ( since free and i've heard its better then xSplit )

PC Rig :

CPU - Intel Core i7 2600 @ 3.40GHz
GPU - NVIDIA GeForce GTX 760 - 2GB ( ASUS DirectCU )
RAM - 16GB - 1333Mhz DDR3
SSD - 256 GB Samsung
HDD - 1TB WD 7200 RPM
Res - 1920x1080

SpeedTest,PingTest and Testmy.net

If u need anything else, plz just ask.
Thx in advance.

Check if it still happens using 1500 video bitrate. I'm not sure how to use the OBS network settings because i dont see any change in ping while streaming, but if that fixes the issue then you know that you're just close to bitrate limits

But if i put 1500 bitrate, then im not sure that i would be able to stream even 720p with 60 fps if im not mistakin' ?

You can stream pretty much any resolution with any bitrate, it just might not look how you want it to. There's no point using all of your upload bandwidth to the point where the game is starved out and lags during stressful times - the latency settings in OBS might help, but they won't fix the root of the problem if you're setting bitrate too close to your upper limits

Yeah i know its upper limit, but still i have arround 500kb free, so i think that should be enough for Moba game @ 1920x1080/29-30fps with 2000 bitrate ? Just that small problem that i have big ping inside Dota ...

I think the max bitrate you set isn't actually the max bitrate, it''s kind of average and the bitrate can go over that number during high motion scenes, depending on how high you set your buffer. I might be mistaken but the maximum bitrate I can use with my 1m upload rate is around 650 with a skype call and a game, with 400 buffer, and the bitrate displayed on OBS while streaming goes as high as 850~
Try 1500 bitrate and 720/30, you'll know if the problem comes from there or not, and then crank up the bitrate gradually as long as your ping isn't affected.

^He's using constant bitrate so it shouldn't do that

The second test says 2.2MB up, also your connection to twitch server is not necessarily as fast as speedtest server. There's a tool to check ping to list of twitch servers, but not bandwidth AFAIK.

If you use 2000kbit for video, 160 for audio then you're cutting it extremely close to ~2.2-2.4mbit up. You don't have 500kb/s free

I've got CBR checked too though if that's the constant bitrate thing, and it still goes higher than the max set bitrate. Maybe it's a problem on my end.. It's not like I have many reasons to stream anyway

CBR + strict CBR (or cbr padding, whatever) shouldn't do that. With 2000 video bitrate cbr set and 160 audio, i'd expect up to like 2200 from OBS, but other stuff, general internet usage can add up. With 0.7 up, i got some latency issues using 400 video bitrate, 128 audio - because of internet usage on top of that. I've got like 7.3 up now and can just stream at twitch limits and laugh with still 30 ping to outside of UK which is nice.

So im not able to stream 1080p with this upload right ?

I will have to go for 720p ( 30 or 60 fps ) ?

P.S. What about music from Spotify or Soundcloud ? Im also using that...

you can stream whatever resolution and FPS you want, but less bitrate = less quality

it doesn't matter where audio is coming from, you just have like 160kbit/s audio bitrate on top of whatever video bitrate that you have set to consider

And i saw couple of streams where they stream high motion scenes with lots of pixalization, so i would like to have clean stream even @ 720p but when i move my camera fast, to be clean and smooth. What should i do about that ?

The only way you can really do it is by using "too much" bitrate for a given resolution+FPS, because you need enough bitrate for the high motion scenes to look good, even if regular stuff needs 1/3'rd as much. Sadly livestream is not like offline where you can use a much lower average bitrate but use more bitrate where you need it and less where you don't, we don't even have variable bitrate on twitch any more since it was causing stability issues(?) so the only option is to use a ton of bitrate for that resolution+FPS

try 1280x720@30fps and consider trying medium preset for that instead of veryfast at that low of a resolution and FPS, if you're not playing a game that uses a lot of CPU across multiple cores
