Hello,

I just started streaming some CS:GO a few days ago. My viewer telled me, that my stream quality is very bad compared with other streams which have the same settings like me.

My Speedtest: http://www.speedtest.net/result/2929634773.png

My OBS Settings: http://www.pic-upload.de/gal-465127/cn8g3v/1.html

My stream (watch past broadcast): http://de.twitch.tv/cptblackevil/profile/pastBroadcasts

I tested everything... I changed capture sources, stream resolution, bitrate and much more, but nothing...
My quality is still bad and I dont know why. Other streams with this high bitrate got a very great quality, but not me... Why?
I hope you can help me to get my stream quality better.
Thank you very much.

Now I´m watching my own stream on my notebook..and the quality is bad for such a high bitrate... for example it is very hard to read texts or words on stream. Just look on my desktop shortcuts and try to read their title, I think it is just too hard to read them which such a bitrate and my upload speed.
If I watch other streams, which got 3500 bitrate, their quality is pretty good, not like mine...
You can see my problem in everyone of my past broadcasts. I captures one a few minutes ago and I also streamed my desktop, so just take a look.

Well, typically, fonts being hard to read has very little to do with bitrate or anything. Consider the following: you are downscaling by quite a bit (from 1080p to 720p), some quality loss particularly in fonts is unavoidable. You could consider going with a bit less downscale (1.25 -- 864p). Your system should not have an issue doing 864p at 60 FPS.

If I change capture resolution to 1080p, so its 1:1, the quality is just awesome, like I want it to be. I tried a lot of settings with 720p, 1080p and 864p... The Quality is great with 1080p, but the others are bad...
I think my problem is the downscale process which makes my quality terrible.

It really is not terrible. Anyhow, if you do decide to go with 1080p, I would highly advise against doing that in 60 FPS. 1080p@60 FPS is very hard on the PC, the connection and on the PCs of the viewers. Limit it to 30 FPS if you do decide to go with 1080p.

Don't be so focused on text quality in an FPS game...

When you downscale, text always suffers the worst. Other than text, that image quality is about as good as you can reasonably expect for livestreaming. Going up to 1080p for an FPS game is going to seriously raise your bitrate requirements, 4000 at a minimum for decent picture quality.
