Re: Logitech c910 and 920
You don't have to have a direct link though some say it's better during shows and such but I have no issues using wifi while I'm streaming.
Here is a photo of me taken with my settings. It looks very crisp and clear and the custys all say it looks good on their end too. Sorry for the random face, I had a long shift and still had my whore make up on and look like I have the thousand yard stare lol.

This is what my settings look like from my c920 and they are pretty clear. I had to play with it as well when I first got it.
