Question / Help Visual Lag/Input Lag while streaming DotA 2

Hey guys,

I'm trying to stream DotA 2 via Twitch.TV with my computer but I experience visual lag/input delay. The game itself is running smooth but my input seems to be slightly of the edge. Due to high APM I'm very sensitive to this and this almost does not allow me to properly play the game at the level I'm used to play... it's far from unplayable but it is affecting me considerably.


Here is information from testmy.net regarding my internet connection:
arrow-down-doubleM.png
Download :: 6.6 Mbps 828 kB/s
arrow-up-doubleM.png
Upload :: 2.2 Mbps 281 kB/s

I've noticed that in net_graph stats the value next to FPS is cycling from below 1ms up to over 8ms... have a look at this screenshot:

Not sure though what this number is telling me...


And here is a dump from my recent streaming-session:

This sounds like something that happens in multiplayer games when there's higher-than-normal ping. Try turning on "minimize network impact" in broadcast settings, and/or turning down bitrate a slight bit to make sure there's enough room for the game, whichever works. Just my suspicion though.
