When I first started playing CoD4 online about a month ago everything was fairly fluid.....lately I've sometimes been noticing guys running where they sort of jerk across the screen....a bit laggy......today it got ridiculous w/ the lag....the shooting was late the staggered/choppy running as well. Is that because someone has a crap internet connection? I don't think its at my end my ADSL has been fine in the past... or is my GPU crapping out? My MBP is esentially brand new and has been fine otherwise w/ no graphics issues whatsoever. Also, has anyone noticed on some levels there is artifacts when you turn quickly in a room? It looks like a line across the screen is offset as if the screen couldn't redraw fast enough. I've noticed it in the beige/brown building level....if you're running into a room and turn to navigate.....seems to be some kind of glitch as it doesn't happen on all maps. Just wondering if anyone else has experienced anything similar?
