2 hours since gameplay (didn't play for almost a year but started playing it again now) and didn't run into any zombies yet LOLL (2 towns around the east coast). I don't prefer running into any of those zeds as they're quite glitchy and can go through walls, invisible zombies (drop through ground and teleport behind you). It's almost impossible to kill a zombie without bleeding and risk dying if without any rags or bandages.

Same thing, FPS related lags (as in ~15fps) in even small towns such as Solnichniy, haven't tried big cities yet, can't imagine the lag that might occur LOL (maybe 5-10 fps???). Computer Laptop Specs:
Razer Blade Pro 2014, Intel Core i7-4700HQ CPU @2.40GHz, dual slot 16GB DDRL3 RAM, Windows 8.1 64-bit, NVIDIA GeForce GTX 860M, running DayZ on SSD (512GB) and just FYI, I plug in my charger when I play games. I play DayZ on the latest stable build with all settings (e.g. rendering, quality and textures) at either very low or disabled with some at normal (those that don't hinder with performance too much). Overall, this game is still playable and enjoyable but gets a bit frustrating when entering towns or cities (maybe perhaps too many entities to render at once with such a long view distance?).
