Update felt weird for me. On more than one occasion I was shot and killed by someone before they existed as far as my screen showed.
In one case I was firing mg4 spam into a doorway, then I die, then this guy appears and starts shooting me.
Another, I'm running up to a corner to peek round, but got shot by someone round the corner (about 10 metres away) before I even got to it as if their game had predicted I was just going to run round the corner.
My average ping on the server was 40, network smoothing 0 and high network update rate.
I might increase the network smoothing a bit, I was using 10 before.
