You can say that it's not induced, but that would be inaccurate- as if there wasn't some random variances, due to a physics model that doesn't work consistently to a random-walk algorithm for in-flight behavior, you would get 100% of the shots 100% of the time if they're properly lined up. I've observed a bit of this myself in the game. "High latency on your wan connection" would also count as a cause of Jitter. And I don't seem to recall some of the other online deathmatch type games having quite so much issues with latency- moreover, I've noticed the issue in question from time to time and I don't HAVE a really high-latency connection and haven't had one for quite some time.
Uh... I'd not heard the term before and I've been at doing game dev for a bit now.PS: "Hit-scan" is an accepted domain term of players, modders, and many developers and could not be called "incorrect" in the slightest.
