Mumble – talk with your fellow gamers without the lag
Don't you just hate it when you are yelling to your teammates when you are playing via virtual LAN setups - only to find out that your voices and your game sessions are not properly synchronized? Think of lag times killing you so badly that you wish it's easier to just type. Fret no more. Here's Mumble to the rescue.
Mumble is an open-source software for chatting while you are gaming. It promises low-latency, but still delivers high-quality voice transmission. Give it a try - you might just escape that next chain lightning from the enemies.
