I am getting stuck on zombies and the environment so much more since the update and my setup nor internet has changed. I have gigabit internet but I live in New Zealand so my ping has always been around 300, but I have been fine playing in the past with it. I even struggle to block while clearly holding up my hands and walking backwards it doesnt put me in block mode. Zombies seem to have a collision box that seriously messes with me having much of a chance now with the desync.
If you would like to see how bad the ping is affecting me especially in close combat please see this short clip:
