At the moment no sa servers are online, only international 300+ ping servers.
The game has some bugs to iron out, but thats expected for a new release. You can set your FOV, MAXFPS and all those things.
Sounds are a bit arb, ppl will be firing their guns rather closeby and sometimes you can't even hear a team mate firing an Ak right next to you, sounds like a silent weapon. The sounds are a bit muffled, with a very "mono" type sound allround. And sometimes the directional positioning of the sounds don't work. Also explosions sound a bit meh. Nothing here patches can't sort out though.
Other than that the game feels good. Pacing is good, hitreg (even with lag) is very good, and the game itself runs just about as good as MW2 dit, but looks better. it doesn't have that full on consoley feeling that mw2 had.
