Question / Help I can't get the good settings for my dota 2 stream

Hi, sorry about my bad english, it seems i can't get the right settings in OBS.

First thing, this is my bandwith, and my upload rate is pretty bad.



Now my spec :
-Core i7 3770k ivy bridge
-Nvidia Geforce G1 Gigabytes gtx970
- 8 gb ram
- SSD 500 go

So what are you guys are suggesting about the bitrate i should set ? I want to use twitch to stream mainly dota 2,
(i'd like some fps like evolve too, but i guess that s impossible with my upload)
I have trouble finding the right resolution ( both in games, and in OBS) and the right amount of bitrate.

Yesterday i tried a lot of differents settings, with a friend telling me each time if it was a little better, but i can't find
the optimal ones, the video is actually not bad, but if the camera moves even just a little, you can't even read the nicknames on people it s just too bad.

First do you thing do you think it's impossible since my upload rate is that bad, or does it seem achievable actually ?
What settings should i have ?

I'm sorry if this have been posted a million times, i really want to know if i should give up or not.
 
Yeah your upload is really bad. You can try something with 500 bitrate and 500 buffer size. Make sure to check "minimize network impact" in settings, with that i7 you can try faster/fast preset for Dota 2 to compensate low bitrate and throw more cpu usage.

Thats best what you can get. If you dont get ping spikes with 500 or dropped frames you can try increasing by 50bitrate.

Resolution..well try 854×480 (downscaled from 1920x1080) and we will see how it goes. 30fps ofc.
 
Yeah I would definitely not go over 854x480 30fps, and with that upload I would not go over 500kbps bitrate. You should definitely consider upgrading to a better internet package if you want to stream properly
 
Thank you both for your help, i tried with those settings, and when the camera moves, it's really disgusting to watch.

I've contacted my ISP i should have 5-8 mbits upload, with this it should be fine.

Thanks again for taking the time to answer to me, have a nice one.
 
5-8 mbps should be all you need. I would recommend using quicksync encoding, 1280x720 60fps and don't go any higher than 3500kbps bitrate.
 



Here's my new conn. I'm very happy with the upload now, but i still have trouble making it work.

I really don't understand because the problem happens sometimes after 10 min of streaming, or after couple hours.

I tried to use the settings you guys recommended. First, using quicksync, i enabled the integrated HD 4000 card i have,
updated the drivers like asked, and it worked good, at first.
I streamed like 4hours of dota 2 with 0 problem, then some viewers told me the video was buffering, like a lot. I watched my twitch too and i saw it too. So i lowered the bitrate (to 2000), the problem was still the same. Then came the :
QSVHelper.exe stops working

Sometimes QSVHELPER dies after 10 minutes, sometimes i get to stream 1 hour with or without lots of buffering. I looked in this forum and saw it was a problem of intel HD drivers with win7, which is my OS.

Then i tried NVIDIA NVENC, which takes a lot of ressources, even with games like dota, i can't play like usually, cause
i got big fps drops... and the twitch is buffering even worse.

So i tried x264 too, i have a red message on OBS window saying the CPU has too much work.

Since my windows is a legitimate copy, i really want to change it to win8 in last resort. Do you guys have any idea ?

I'm gonna try to bump this and add new things :

I still have the same problem, i found the MP version on this forum (i guess, which seems to work almost flawlessly)

What i don't understand is that it uses x264 if i'm not wrong, and it's not impossible to use quicksync or nvidia.

I'm not having any problem with CPU usage, but with the OBS 0.64b, i m getting the red message, and it usually closes the game.

I'm also very unhappy with the twitch buffering A LOT sometimes, or not, depending mostly of stars aligned to earth or something. I tried hitbox TV and it worked very good.

But i really want to use the quick sync, since it allows me to play games without any stuttering or such.

Can you guys find the problem in the log ? Or should i just upgrade to win8 right away ?
 
if nothing seems to fix the issue, personally I would do a format and fresh install of Windows. And yes, I would definitely consider upgrading to Windows 8.1. OBS will perform much better.
