Hello dear users,

I installed OBS to stream computer games. I'm with Windows 10. I started streaming CS:GO on Twitch.tv (not an ad) but the quality is bad. Any ideas how to fix? Here is a video who shows the quality - https://www.twitch.tv/milusheff/v/53412871 ( not an ad, skip to 1:40 ; my PC specifications are under the video ; OBS setting for the gaming capture: http://imgur.com/13wPyhB )
Need yourr logfile where you streamed for 5 minutes or more. preferably when you had an issue.

Please define bad quality as well. are you talking burry when moving? intermittent stuttering? buffering? low fps?

https://gist.github.com/74a82806220d00983fa5 here it is. I dont have problem with the FPS. When I move the quality gets bad.
in video tab of OBS:
downscale to 1280x720 (1.75?)
bilinear or bicublc filter (bicubic sharper) or lanzcos for a dithered smoother look)

advanced tab:
x264 preset veryfast and if downscaling gives you a little more room you can try faster but no lower. this will be game dependent but I would advise newer games to stick with veryfast

profile:main

Code:
Interface: Realtek PCIe GBE Family Controller (ethernet, 100 mbps)

you might check drivers for your network card. you should be pulling 1000mbps from your router unless it is slower. this is normally fine but can show use of improper drivers which can affect streaming in some situations.
I would recommend pulling all of the latest drivers from your motherboard manufacturer's website as these are the best to use. Get Chip-set, network and audio drivers from this site.

Encoding tab:
buffer and bitrate: both 2000 or both 2500 (this will depend on maintaining 2mbps upload to your ISP all the way to twitch. even if you have 5Mbps upload this might not be the case. use this tool as a reference to find out where you are at and post a screenshot of the results http://www.teamliquid.net/forum/tech-support/478845-twitchtest-twitch-bandwidth-tester Make sure nothing else is running during this test

audio format: 44100Hz or 48000Hz this will need to match your audio devices in windows recording and playback devices under the advanced tab of each device. all devices must match to maintain proper audio and in some cases performance of stream.


Other thoughts:
your source game: you play CS:GO at 1280x720. this does not match your base resolution but the aspect ratio matches. its just something to keep in mind if you change resolution in game often. Also note that lower resolution can use more CPU due to draw calls and higher fps. so if you are well above 300fps you might consider using 1920x1080 in CS:GO.
