Ok, so when you first start things either go wrong, or whatever, so here is some quick info if you are just starting out.
1 - the bloom is way over the top. I personally have disabled it for now, until its turned down a wee bit.
to turn it off, open my docs/bfbc2beta/settings.ini and find "bloom=true" and change it to false.
2 - The voip does not work yet.
3 - The server browser is very slow, and sometimes you cannot join an apparent server, showing slots, and sometimes you can join apparent full servers, its all just trial and error, find a server with say 25-28 players..that normally works for me.
4 - The uav goes up using R and using F.
5 - Sometimes when you log in to EA, it will not show your actually rank (may say rank 1) but when you join a game, you will be at your actual current rank.
6 - There is hardcore servers, they have HARDCORE in the server name.
If i think of anything else i will add, if you know anything i have not mentioned please feel free to share
