your up is faster than your down? you need to get in touch with your isp as they have it backwards... on adsl your download is normally 20%up 80%down. a faster down speed is essential for gaming as your downloading more from the server than your sending to it. streamed games are supposed to negate the need for high end hardware but you still have to have a minimum. whats your specs and what does the game require as a minimum?

Look into where the closest twitch.tv server is that you're connecting to when streaming.

A lot of people seem to fail to understand that testing your connection to a location near you (<50 mi) yields poor representation of your speed if the applicable server you're trying to stream to is well over 2000mi away from you.
