My livestreams always have artifacts?

I have had the problem for a long time that my live streams on YouTube and Twitch always have artifacts and I don't know how to solve the problem.

I had a Ryzen 5 1600 before and now I have an i7 10700F.

It can't be because of the bit rate, because a friend has exactly the same settings and everything looks fine with him.

It is still due to the bit rate. To be more precise on your internet. You can set the bit rate as high as you want, if your upload is not good enough, there are artifacts. Go to https://www.speedtest.net/...est.net/de and do a speed test. You may be able to set the stream to 720p to counter the artifacts.

My upload of 10mbit should be enough
