My framerate was incredibly low with 1.6.0, maybe around 5 fps. The 1.6.0.1 hotfix improved it, but it's still unplayable. I was getting about 20 fps at first, then plummeted to about 5 again once zombies started chasing (which got me killed, and I'm still a little pissed about it!). This was sunny weather, indoors, in Gvosdno, on one of the Virginia servers. In the past the hotfix would clear this issue right up, game would run very smoothly at 30+fps in all weather conditions with lots of zombies, but that doesn't seem to be the case this time.
