Sorry if this has a thread already please pass on the link.
Ive decided to broadcast playing Forza 5, but haveing problems, my internet speed and upload seem ok, according to twitch i can run at 2500
But all the settings make the stream lag? 
Is there something i can do about his?, i use wired connection also…
Do i need to do something on my router? its new virgin super hub.
Thank you.
Put the twitch connection on “High” that’ll bring the quality down a little bit, but it’ll still be great along with smoothing out the stream (hopefully). My connection is not nearly that good, you should be fine bro :).
Thank raceboy for your reply. Somebody cares! 
Managed to stream yesterday. And some people said it lagged at first but then smoothed out. I enabled multi-Cast on my router it said something about streams lol.
Thanks again.
