Opensource freelancer I came to Western Q3 since 2005, in 2008 I proposed my first patch to the Smokin' Guns team. Official member since january 2009, now I'm the official Smokin' Guns Linux release maintainer.
It will be soon possible to keep lagometer while playing so you'll be able to debug network troubles in live.
You'll just have to set "cg_lagometer" cvar to "2" in your console.
But this will only be available in v1.1b4 :P
