When I stream e.g. On Twitch (have 10mb / s upload)
What would be the highest how I can set my bit rate?
What streaming software do you use? So OBS or Streamlabs OBS or XSplit etc.
Because Streamlabs OBS has a lossless setting, so I've always done well with it. At 10 MB / s I would recommend a bit rate between 3000 and 3500. You can play around and slowly go up with the value and see whether it gets better or worse.
MfG Ash2Say report any questions ✌🏼
And anything higher will of course give better quality, but you have to pay attention to the people with not so good internet. So it is up to you, as I said, if you want to go higher there's nothing in the way of your speed but better keep it between 3000-3500, such values are recommended.
