Ahh I jumped on this with Badboy briefly over the weekend.
first impressions.... I like it 
 
so much smoother than arma2 

 also the zombies are more zombie like? imo 

 just their movement, managed to kill my first zombie by throwing a book at its crotch...RESULT!  haha
still runs a bit meh given that arma3 is still a little clunky, and trying to get decent fps is hard, well... getting around 40-60 I think but changing settings doesn't seem to change it very much at all 
 
though BB did say they had fixed zombies so they couldn't go through walls... 2 mins later I watch a zombie hobble towards a wall and pass straight through it... not as fixed as he thought 
 
believe my guy was a ranger on the EU16 new haven server? are characters persistent on the server, i.e. will he still be ontop of the tower with the lewts I gathered if I jump on tonight? 
 
edit: have 
[email protected] and 2x680, any tips for getting the most fps and it not looking like poop? need to force sli maybe? (not even sure if it was running sli or single card... haha )
