Battlefield: Bad Company » Battlefield Bad Company 2 : Playability issues.

Hi,

Issues abound.
1) The only way I can use 100% of the viewing area of my screen is to run the LCD at 1920*1080 at 24 refresh rate. I bump it up to 60 and I lose my overscan settings. ALso the image is dim, and there is no anti aliasing.
2)Sound. Every sound work normally, except gun fire. Its alway coming from the right hand speaker.
3) Low ass frame rates. At medium range, watching a bad guy run across the screeen is like watching a poorly drawn stop animation.
4 Constant disconnects from EA.( Has this issue on the PS3 as well, but damn, how hard is it...)

Any help will be apprecited.

I didn't find the right solution from the Internet.
