Heres my initial thoughts posted on another forum:
Well just played 3 games.
HOLY_SHIT
Really fucking nice so far.
Sounds (guns / environment etc): Really atmospheric, hearing gun snaps etc around you. Really good.
Animations: Awesome, you kinda launch yourself over things rather than being like a jumping horse and just leaping clean over it with all your gear on.
You can see glints and sun reflections off snipers scopes in the distance which is so fucking cool.
Movement feels awesome and so do guns. Grenades arent throwable for fucking miles which is good.
Runs pretty decent, on my PC (amd phenom X2 550 @ 3.7ghz, 4 GB DDR3, HD 5750 overclocked a bit) im running with AA on and most settings max (had 2 on medium which where shadows and i think environment details or something. And was playable, some slow downs but could be due to my PC running like dick lately. Needs a good reformat as even WoW etc runs bad in places.
Really cannot complain yet seems so nice to play. Any other questions lemme know and ill find out.
Sorry for all the swearing i was pumped.
