Difficulty sreaming

Hello,

Over the weekend i have tried to stream the server, but when I log into the game OBS drops thosands of frames and the bit rate drops to 100kbs-500kbs.

To delve abit deeper into this, my stream only begins to suffer when i actually have a chareter in game.
When I am sat on the charecter select screen or i have wow closed i get around 5000 bit rates.

It is only when I enter the game world that the dropped frames and the bit rate drop constantly.

Has anyone seen this or knows a fix as it seems the be related to the client?

Is it possible that the WOTLK client is taking all the bandwidth ?
