Why does bf2 not run well?

My specs
Sapphire x1900gt
AMD 3800+
2gigs ddr2 800
msi 550
Windows Vista Home Premium

Why when im playing sharqi peninsula in bf2 (all highs and 4x aa) does my game get about 20-30 fps average? Also it drops down to 15 fps every minute. Why isn't my game running 70 fps?

(I also have the latest vista drivers from ATI)

Any other suggestions, cause i do have a xp hdd that i could use....

Overclock your cpu and ram you should get better frame rates.
The game is really cpu sensitive.
Yes also try and get rid of VISTA.

What res are you playing at? If its 1280x1024 and you have everything on high with 4AA, I wouldn't expect an x1900GT to give you 70FPS. While not bad, that card isn't near the top of the line, nor was it ment to be. ATIs GT cards aren't that good. Read this review and look at the toms benchies. You'll notice that this card isn't supposed to spit out 70FPS at high res with max details and 4AA.

Its vista i bet.. try xp... btw u gotta reformat if you changed hardware sense you got vista installed.

Hey thanks buddy , its kinda an emotional moment , to think i just started out oH well 500 here i come

I've not played BF2 on Vista buit I'm guessing there is a performance hit.

Sharqi is quite intensive near the TV station & Construction yard due to heavy use of dynamic shadows (if you have them unabled). Have you tried turning shadows down or off?

I also noticed that if you have HQ AF or Adaptive AA enabled then they take a huge performance hit too, particularly near bushy areas.

Can you copy your video.con file (My Docs\BF2\Profiles I think) it should open in notepad, and post it so I can see your settings?
Also what settings you have forced in Catalyst Control Centre?

I get somewhere around there... 8)

prozac26 IT WAS YOU that told me that,

how do you get them frames. I play at 1280x1024 and i don't have vsynce on......

One of my old 7800GT COs was more than capable of handing Battlefield2 at 1280x1024 with 4xAA, so an X1900GT should be fine.

WTF? BF2 is a ram hog and vista does lack behind XP.

ok- i was attempting to read this thread and provide some help and I have had to stop myself.......It's NOT necessarily VISTA---holy crap OMFG. while it may suffer some reduced frames VISTA can be tuned even with the current beta drivers to get maxxed fps.
First off run the game in single player with max bots. Whatever that fps value is should likley be what you could hope to get on a server with <70 ping. I have to agree with some of the other folks as well that the vid card you are running is not upto running bf2 maxxed out without some OC work. A few other things thaty can slow you down- since it's a fresh install look at the auido settings, generally get better fps with eax off, and tunr auido to hardware enable if you have a sound card as this will free up resources. also make sure the res that you are running in game matches that of your desktop that helped in the past as well.

cheers

Is it because we actually know what we're talking about? Battlefield2 under Windows XP already needs 2GB of RAM, so when your bloated operating system(Vista) uses up 1GB of RAM at idle, you're bound to have a problem.
