7800GT and BF2 FPS issues

Computer specs 64 3000+ OC'ed to 2ghz, 1 gig Corsair pc3200. I recently upgraded from a 6800GT to a 7800GT in hopes to play BF2 online with high graphic settings. My NVidia settings are all set to Application-controlled. I can play BF2 online with graphic setting of Medium @ 1024x768@75Hz with no AA with an average of 35 fps. 35fps barely makes it playable and sometimes things come to a standstill when there is alot of action going on. I am using 81.98 drivers and conducted a format and clean install of XP upon installing the 7800GT. I fully feel I should be able to play with high setting and possibly with 2x AA. My 3DMark05 score is average 7200, which is 2300 points higher than my previous 6800GT score.
My question is, what is killing my graphic performance, my cpu possibly? My PSU only pushes 18A on its +12v rail. I am soon to upgrade to a PSU that pushes 30A on its +12v rail, but I do not feel as though this lack of Amp is the major issue

i get the same thing except i have an amd 3700 at stock speed and a gig of patriotmem. i bet that i need 2 gigs to run on high

specs
amd 3700
XFX 7800gt
Asus A8N-E
seagat 7200rpm 160gig
1 gi pc3200 Patriot mem at 2-3-2-5

ok first of all a 7800gt requires no less than 26A on the 12+ rail 8O second your cpu is cause a tad of a bottleneck. In SLI a 7800gt needs 33A look to buy a new psu that has dual 12v+ rail with at least 34A total. and 450watt min.... :twisted:

Certainly wouldn't hurt to bump up your RAM to 2Gigs for one and the other thing is get a quality PSU. Antec PS2 series are always good. Right now your bottlenecked because of those limitations I believe ...

What The Hell R U Talking About ???...
I Have an AMD 64 3000+ 939 ( OC @ 2.2) + MSI 7800GT and ACBel 400watt inteligent Power series , I EASILY play Battle Field 2 at 1280x1024 MAXIMUM graphic + 4XAA in about 60FPS and More !!!!... Even with my Previews 6800 128mb AGP i Played Battle Field 2 az 1024x768 Max+4XAA with 60FPS , I Dont Think your CPU is bottleneck !!
(even with stock 1800MHZ) , and 1GB ram is enough , I Dont know much about PSU , but my ACBel 400Watt isnt Blow yet !! So I Recommanded Install a fresh windows XP Service pack 2 with all of your lastets driver (mobo chip (nforce ,etc ) and another think is disable EAX if you have onboard sound card , and try with out overclocking your CPU )
February 6, 2006 10:46:14 AM

my specs are:
intel 2.4c ghz
1 GB pc3200 ram
radeon 9600 pro (256 mb) (o'clocked by 10%)
etc,etc.....

is it me or am i the only one who can play BF2 in 1024x768 in high graphics with 2x AA with 40-45 FPS with my specs????????

For better BF2 gaming I suggest you get 2 Gb of memory. I have experience this before, upgraded to 2 Gb memory and fixed the problem.
Games that are coming out right now are becoming more graphics hungry and great games like BF2 and FEAR would require more than 1 Gb of memory to run smoothly. So take out your buddy's memory and add it to your mobo, it should fix it.

yep, you certainly are an exception my old p4 2.66 and 9800xt could only do medium.

Well BF2 has some well documented issues with high end cards, have a look Here.

It also widely acknowledged that high and maxed out setting require 2gb of ram to be smooth, but that probably is not your current problem.
Low ram will cause long load times and start of map stutter.

A lot of fps problems are caused by sound cards in bf2

My PSU is an Enermax noisetaker 420W. It does not have a 6-pin connector so I am having to use a 6-pin to a dual 4-pin connector. Since
I am using this type of connector, I have two seperate 12v rails feeding the video card. Each 12v rail has 18A, this should give me a total of 36A for the video card, yes?

Memory is 2x512 Corsair XMS 3200C2PT with timmings set at 2-3-3-6-T1.
Sound card is Sound Blaster Audigy 2 ZS.

Bingo I would prob say that was the issue. A lot of people using the audigy complain of serious fps issues.

Read this thread,plenty of disscusion and some solutions Here

Thanks for the link. Guess I could switch to the onboard sound and see if that resolves my issue.

Anything is worth a try, yours should easily be able to have maxed settings with a 7800.

The prob with BF2 is its a complete pig on some systems and any number of things can be at fault.

I would recommend more ram for it as though.
February 6, 2006 1:59:02 PM

My next purchase is memory upgrade from 1g to 4g. Will just have to remain playing on low settings till then.
February 6, 2006 3:30:41 PM

You will take a performance hit with 4gb as running all four slots is slower than just running 2. 2 gig is IMHO the sweet spot at the moment 2x1gb in dual channel 1t

I was running a eVGA 6800GT PCI-e for a few months, playing BF2 on all highs with a few lag spurts during explosions/arty strikes. So I dropped my settings down to medium. Worked fine.

System:
ASUS A8N-SLI Deluxe
AMD 3800+ (venice)
eVGA 6800GT 256mb
1gig OCZ DDR400

Then I had bought a 2nd gig of RAM...helped even more. But then around christmas time I had recieved an eVGA 7800GT to replace the 6800. Now...I ran everything on high, 1024...and it was almost lagging MORE than my 6800GT. Pissed me off...but then I noticed while I was tweeking some things. My timings were off on my RAM. I thought since my RAM settings were default-AUTO'd...that my ram was set right. WRONG. CPU-Z...was displaying 100MHz bus.



Then I took extra close notice to my BIOS...was saying my ram was only DDR200...that ain't right. After running 3dMark05 and only scoring 6800, which was compareable to what my 6800GT was getting earlier. I tweeked my BIOS a lil bit...updated it to the newest. Went in and manually set it up...now CPU-Z was displaying something a little better...



3dMark05 scored 7600...and BF2 runs in 4x AA, all high 1280...fine. So definately check out your ram timings...1 gig shouldn't hit the FPS that hard. But your proc/ram may very well be your bottleneck...as other have said. Hope that helps.

ATF_DeeJay,

Thanks for the input. Unfortunatley I am currently out to sea, so I will not be able to check the bus speed till this weekend.
February 8, 2006 3:32:18 AM

just to give you a point of reference.
i have

prescott 2.8 o/c to 3096
1 gig ram
evga 6800 GS no o/c brand new card
300 watt zalmon high power 18A 12V
Audigy 2

i play Batt2 at 1152X864X85
i have AA set at 4X
some hi effects and some low. i judged based on tweak guide.
i get avg of 60fps .
in heavy action with alot of players it dips to 28-29 fps. but not for long.
i am still testing this card to see what the sweet spot is. i would like to mainain 50-60 fps in heavy action.

any opinions or help from someone would be appreciated. I upgraded from a 9800 Pro 128mb which I have to say was a great card. it would definitely play batt2 but not at the settings i have now.

Try the 2 Gb solution, no doubt you need 2 Gb to play BF2 smoothly. And if it is the sound card decreasing the FPS, then go to Device Manager and disable it and play the game to see there is a difference in frame rates.
February 10, 2006 7:24:18 PM

I had issues with BF2 as well...

Running 64 3000+ oc'd to 2.1 (233fsb)
nf4-sli board
1 gb 3 3 3 8 1T 466
2x6800gts
sba2

With 1gb i ran fine...high fps, until it would suddenly stop, and lag (running off the hd...), then it would go back to normal, then lag, lag lag...

I got 2gb 2 3 2 8 ocz, running at 466 3 3 3 8 1T...

Now, even though i've taken out one of the 6800gts, it runs flawlessly...

I run 1152x864 with everything on high. I run all my games at that level except eq2 which runs at 1600x1200...

2gb completely changed my game. I never stutter or lag now. I did the same for a buddies machine...got him 2gb for his 3500+ 9800pro, sbl machine. He said he was about to quit playing, until he got the increase in ram...now everything runs great.

CPU-Z shows my Frequency to be at 111.5Mhz...FSB:D RAM CPU/18
My BIOS shows it to be 225. So whats the deal here?
February 12, 2006 12:08:17 AM

Figured out how to change the bus to 200Mhz. That made a major difference in the Sandra Memory bandwidth bench test.
February 13, 2006 6:04:44 PM

BF2 at 1024x768 at 85MHz with my set up on high settings at 90 FPS BOO YA!!!
February 19, 2006 6:45:11 PM

yeah i have an xfx 7800gt at 450mhz, amd 3700 and a gig of ram and i cant play on all high without frame rate drops.

I have had issues with BF2... 2 gigs needed... if you alt tab to desktop
use task manager and check it out BF2 will eat up gig easy then PB does a scan look out
