Right now isn't the open beta, it's the beta for those who preordered.
I'm in, but there's a huge fucking shitstorm with shit spattering the walls of nearly every PC player who plays with custom remapped controls.. The mother fuckers (dice, the developers) obviously didn't account for the fact that some players might want to change the fucking default keyboard/mouse bindings.. No one can remap the mouse buttons from their default bindings, as well as for some of the keyboard settings lol..
So I + many others can't play it. The actual game looks amazing though, just can't use it because I've been using my key/mouse setup for ages and can't be bothered to learn a new one.
Technically it is the open beta, at least thats what its called on the bf3 website. Those who pre-ordered through origin get a 48h head start. Tomato, tomatoe.
The keymapping thing is bullshit and hopefully they intend on having an option to remap the keys once the game launches.
It also needs better multi-monitor support. I have 3x 27" monitors and the game looks like absolute crap. I logged in with my roommates origin account and played a few games. At 5760 x 1080 it won't full screen and the ui dissapears. I'm using 2x gtx 580's in sli w/ nvidia surround. I really hope they fix this by the time the game launches because playing bf3 on 3 monitors would be fantastic.
