Semi-off-topic: I hear a lot about certain add-ons being resource hogs, but how does this specifically effect game performance?
I haven't heard much about system lag, just memory hogging. Sounds like if we have multiple cores and plenty of ram it shouldn't be an issue.
I am running my trusty old dual G5 Power Mac with a 6800 card and the only problem I have, before and after Carbonite, seems to be some video lag when there are a ton of players nearby. I have not notice any difference after installing Carbonite.
