I have two computers - one for media streaming and one for gaming. My media streaming machine streams using the Asian P2P Media Streaming software Funshion. I've capped my download/upload speed on my media machine to a fraction of the bandwidth my ISP provides me so I have a ton of download/upload bandwidth to spare yet I am still lagging in my online game, such as Battlefield 3 for PC.
I want to note that according to my ping in-game, I am always under 50 ping. I have pinged Google in Command Line and got an average of 24ms. Here is an example of what I see when I lag in Battlefield 3: http://www.youtube.com/watch?v=WpJBwX3GMGg
I've only noticed lag when gaming. When I am streaming Youtube or browsing the Internet off my gaming machine, I do not notice any slow-downs. I've only noticed slow-downs when playing online games.
I also want to add that when my media machine is not streaming, I am lag free in-game.
