I have hit detection issues. I believe it is almost entirely related to lag. In fact I think it is a clear sign of lag when other signs of lag (jerky screen, no warning deaths, delay in response) are less evident.

Hit detection, or the lack of, is my first clue that lag is going to be an issue.... amazing how I can fire a single shot at someone and the hit detection shows up about a .5 to 1 second later, where as in a solid connection the hit marker shows up near simeltaneously. I'm truly beginning to hate my top notch internet connection.....thinking that if I go to dial up things might improve.

I get the feeling sometimes that Robert Bowling has his hands on the knob and he turns it WAY up and then WAY down.  The inconisistency is amazing.  One game is great and I am in "God-Mode" and then the next game, in the same lobby, is total crap.  Suddenly my bullets have absolutely no power and people are shooting me the INSTANT they come into view on my screen.

Sigh. 

Always! i completely agree with pneumatic

Had the Stay Puffd" bullets today. Had the MK-14 with RF aimed dead on a guy coming to B from A on Bootleg... nearly the whole clip..nothing didn't even bother him. Turned it off.

I wonder why so many people use SMGs and other full auto weapons, then I watch this video and it's obvious. Why bother with burst or single shot guns when you can spray an entire clip and pray that you get those 2-3 hit markers needed for the kill. Sniping is damn near impossible anymore

Got a hit marker and no kill with throwing knife think it's safe to assume it's not all lag related on hit detection.
