i use Skype alot when i'm playing games, and when i'm not... it's great, however it is hit and miss for some people, some get bad lag from it, others see no difference (like me)
yes, but A. Look at CPU usage B. skype transmits all the time, wasing bandwidth on an engine note or silence, where as you can configure teamspeak and vt to only use bandwidth when you actually want to say something!
i dont really care for driving the oval, i think it is a bit boring. Ok, it is fun when you are nose to tail, in the slipsteams. But when your not, it gets a bit repetative in my opinion...but, specialized team speak servers would be nice.
