My ping ranges from 20 to 40ms on my favorite server and I had really bad fps issues this morning. Updated my vid drivers and reconnected and was fine. Died once while testing the new zombie behaviours ( which I think are completely broken ) and when I respawned fps was so bad I just quit. And when I say broken, they are still attacking through walls, walking through walls.. you can't lose them if you LOS them. They just keep coming like before.
