hello dear community

installed bf3 tonight and went over a quick gameplay. 20-30 FPS, sometimes even up to 50. (single player)
my 1st question : will i have the same FPS when i'm playing online? I mean, the giant maps and stuff.

I currently have my settings on the lowest option.

here's my setup:

- 2x 2,6 ghz cpu
- 4 gb ram (64 bit w7)
- radeon hd 6770 (1gb ddr5)

i know this is kinda crappy but i cannot afford any more atm.

2nd question : is there any chance i can archieve higher frames per second? I wouldnt mind if i lose some details or graphics.. you know what i mean

3rd question : i've heard about an "fxaa injector" - graphics mod which should get my performance alot better.

have you experienced anything like this? Am i getting banned when playing online?

that's all for now i appreciate answers

As far as I know FXAA doesn't improve performance by default, you get more frames with it than with in game AA on.
There's probably some config file settings that improve performance, apart from in game settings.
