What internet connection do I need to stream on Twitch, how much download and upload should it be?
Depends on the quality and the fps of the stream
Not helpful but thank you!
To do this, you should first define what you want to stream and how, in what quality and resolution.
otherwise you can stream with each line just asks how good the result is.
Where is that not helpful? According to your question, that was the most helpful answer that someone can give you, you did not provide any information about the desired quality or the fps, and no information such as e.g. Whether you stream with facecam or not. You can't expect an exact answer if you don't give us enough information
He has done his best, your information is just insufficient and if you ask you would also be snotty, as if the other person is to blame for you not providing any information, and you don't even have a clue about the subject. Is that how you are otherwise.
I wanted to stream sensibly on Twitch, but by sensible I meant that you can watch the stream as a viewer without jerking, I don't need a quality like that of Gronk or something it should be tolerable as a viewer, I can't say more about that!
An upload rate of 3 to 6 Mbit / s is recommended for transmitting a live stream on Twitch. A download rate of 4-6 Mbit / s is sufficient for viewing streams.
Yes, but you could have said that from the start. But well, your upload should be around 10 to 12 mbits, your download is not really important for streaming, for pleasant gaming it should already be 2mbits (not the line, but what matters) otherwise it is up to the viewer whether the stream stutters or not
