ive looked into bf2 tweaks and i got some good tweaks which are ok they delete out your team mate sound of thier guns and you can hear the enemies walking around so you can hear them further then you can normally can and you can hear their gunshots from a longer distance as well and also i got some tips on graphics as well what you should put your settings on because the graphics can be shite!!! if you want to ask me any questions give me a shout.
Also their is a programme called hitfixer what i use occasionally so if you want to ask me questions about that im willing to help anyone:)

tweaking is for gays... whichis why i bet all the eaf members do it

most people already know what to put their graphics settings on.

monkeys done his own "hitfixer".

so there.

I think there's some old posts (search for) about the hitfixer

The sound file changes can be detected by server side (ahh my old subject of md5 checks ). I personally wouldn't change this as it's quite blatently not what the game intended.

That being said with the game set to hardware rendering of sound, I found I could hear things halfway across the map. Essentially this meant a cacophony of sound. Having software rendering meant I hear stuff the was closer to me, as in the immediate threat. I just leaft my sound settings on this.

As for graphics I have everything on highest apart from shadows and lighting, which just makes things clearer.

ahh reminds me in the days prior to 1.3 where you could change the graphics to ultra by editing the configs. The ultra graphics causes problems for some people sso they removed it in the 1.3 patch
