Ever since the recent 1.01 update came out I've noticed performance has dropped slightly... quite noticeably
I usually run DayZ around 40-50 FPS depending on how many models are around with slight drops to 1 FPS for usually 4 seconds (which has ended many LADA lives *tears*) but now I usually run DayZ at 25-37 FPS with longer FPS drops of 1 FPS for about 10 seconds, and its even more stutter (that's what I call it) instead of only happening every 4 or so minutes when moving quickly it happens almost constantly!

ANIMATION ISSUE
whenever you have a rifle/shotgun of any kind and either fall so you land on your hands/feet or prone, swivel to your back and stand up your arms freak out, now it's not that bad but it would definitely bug some people, the arms seem to be stuck to a guns grip no matter what, and lets not forget the SKS, Mosin and CZ527 anim's aswell as all heavy weapon anims!
