Hey everyone, so I recently started streaming and have come across a screen tearing issue.I'm new to this whole streaming process so if anybody could help me out it would be greatly appreciated.

Here's a picture of it happening: http://i.imgur.com/5Z5EWuF.jpg

It's only on my stream it tears, not in the actual game itself. The game itself runs completely fine.

Is this what you needed?

Yes. I thought you were using a low bitrate but in fact you are using too much. Anything above 3500 will cause problems, in fact I would go 2000 or lower on non-partner channels for 720p. I see you are on wifi, you may be losing packets causing that effect. Can you try with a wired connection?

I'll try using a bitrate lower than 2000 and see if that helps. Wireless could be a problem but I have a pretty reliable connection because my router/modem is literally sitting next to my PC. Wired is an option indeed but I currently don't have the wiring able to do so. Thanks for the help! If it still happens I'll be sure to report back with any problems.

If you have the router next to you could be a matter of getting one ethernet cable :D
Anyhow, let us know if you have better results with that more reasonable bitrate

I just did a stream test to check if it still had some pixelation...it seems to be fixed. However the video quality is worse than before. Is there a bitrate where I can meet the happy medium between no pixelation and decent video quality?

2000 bitrate for a 720p stream should suffice, maybe you are expecting too much quality out of your stream? Also you can change bitrate without bringing the stream down, so you can try different values yourlself. Just note what I told you before, anything above 2000 will cause problems for your viewers to watch without a partnered stream on twitch
