Not sure if you'll need to hear this, but the new update does have more FPS (seems slower than usual with the smooth lighting/graphics, though. I have to play on the more tiled lighting now), but huge FPS drops in certain areas where I normally won't get in the previous versions, and some invisible walls. I've walked on the road and next to a house and experienced FPS drops. It seems to stutter when I run and it looks like I go really fast. And also I think that looting has increased a bit. Mainly for bags and all that. I was able to get 3 duffel bags, 1 hiking bag, 1 backpack, and a lot of plastic bags in I think two houses. Zombies also seem tougher and faster too. Not sure if it's affected from the higher density of zombies. Some of these bugs may just be my imagination
