Hey everyone. I just recently decided to try my hand at streaming on twitch. I've been reading guides about how to setup my stream and for the most part it works I just need to fine tune.

Currently I can stream well, it loads very fast. Doesn't ever buffer for me on my test end and looks decent enough. A couple issues I am having are:

1) When I start to move around (playing diablo 3) the stream will become pixelated vs crystal clear while not moving.
2) I have a 21x9 3440x1440 monitor and would like to stream in 1920x1080. Right now I have it fit the screen and downscale however it stretches upward to remove the letter box. Is there a way to do this better other than playing in windowed mode or 2560x1440?

My setup is as follows:

Your log isn't showing what bitrate or cpu preset you are using. These are the two main parameters for how your stream will look like. HOWEVER, streaming at 1080p60 is only acceptable if you're streaming to Youtube or are a Twitch partner.

When streaming to Youtube you can send a 9Mbps stream and Youtube will transcode it for you.
When you're a Twitch partner you can send a 3.5Mbps stream and Twitch will transcode it for you.

If not, you're either expecting your viewers to have a CONSISTENT high download connection OR your stream will look like crap once stuff starts moving (which seems to be the case here).

My suggestion: downscale and stream at 720p30 at 2500 Kbps. You image will look great even with a lot going on. You can still play at your preferred resolution (as long as you maintain the aspect ratio).

This helped out. I bumped down to 720p and found out that I was using cpu the wrong way. I had it on ultra fast when I wanted it on slow.

Glad that helped, though Slow is often overkill. I often stream at veryfast. But if you have the CPU for it, more power to you! :)
